Improving device performance of p-type organic field-effect transistor using butterfly like triarylamines

Facile and economic strategy to create a controlled self-structured architecture of semiconducting molecules is very crucial in the accomplishment of carbon electronic devices. A series of new unsymmetrically functionalized butterfly type triarylamines with electron donating/withdrawing substituents were synthesized. Simple and efficient solution based method was used as a successful strategy for OFET with improved characteristics. Binary solvent system with chloroform and toluene (7:3) has improved inter/intra molecular communication in the active layer. The morphology of the films was analyzed by SEM reveals the uniform packing. In addition post thermal annealing has enhanced the crystallinity with minimal grain boundaries. HOMO values -5.1 to -5.4 eV obtained from cyclic voltammetry ensure that these molecules can efficiently transport holes. OFET devices were fabricated in bottom gate top contact (BGTC) architecture by spin coating. Molecules exhibited typical p-channel transistor behavior with mobility up to 1 cm2 V?1s?1 with 106 Ion/off current ratio. Density functional theory (DFT) visualized the packing and interaction of molecules and supported the efficient mobility. Our investigation gives insight into the role of solvents to control the film architecture in solution processing OFET device construction.

Temperature effect on the optical properties of two different triphenylamine-based organic dyes

In this paper, we present the absorption and photoluminescence (PL) spectra of conjugated, metal-free organic dyes, triphenylamine derivatives 3-(4-(bis(4-(5-(4-(hexyloxy)phenyl)thiophenyl)phenyl)amino)phenyl)-2-cyanoacrylic acid (OD3) and (E)-3-(5′-(4-(bis(4-(5-(4-hexyloxy)phenyl)thiophen-2-yl)phenyl)amino)phenyl)-2,2′-bithiophen-5-yl)-2-cyanoacrylic acid (OD3DT), with and without a π-conjugated bridge, respectively, in film at a temperature range from 13 to 400?K. We find that the intensities of absorption and PL of OD3 decrease gradually beyond 200?K, as well as the ratios of integral areas of absorption to PL spectra. However, the other compound, OD3DT, shows a very different behavior. An increase is discovered in the ratio of the absorption to PL integral area when the temperature is higher than 200?K. A π-conjugated bridge gives this compound a higher degree of symmetry, and therefore, a better alignment of the molecules in the film, which causes a stacking aggregation such that the temperature effect on this compound is different than OD3.

A novel pyridyl triphenylamine–BODIPY aldoxime: Naked-eye visible and fluorometric chemodosimeter for hypochlorite

An aldoxime containing fluorescent probe based on vinylpydine-appended triphenylamine–BODIPY has been designed and used for hypochlorite detection. OX-PPA-BODIPY was developed by introducing an aldoxime group into the 2-position of BODIPY, which can be used for the detection of hypochlorite with a sharp color change from pink to green. The attachment of 4-vinylpyridine moiety to triphenylamine–BODIPY constructs a fluorogen with desirable conjugated system. The probe, which displays extremely weak fluorescence owing to the C[dbnd]N isomerization mechanism at 2-position of BODIPY, responds to HClO/ClO? through a dramatic enhancement of its fluorescence intensity. This new probe, a naked-eye visible and fluorometric chemodosimeter, exhibits high selectivity and sensitivity toward hypochlorite over other reactive oxygen species (ROS) and anions. The detection is accompanied by a 20-fold increase in fluorescent intensity (ΦF from 0.02 to 0.43). The detection limit of the probe for hypochlorite is 7.37?×?10??7?M. Moreover, OX-PPA-BODIPY can be used to detect hypochlorite in real water samples.

An AIE dye based smartphone and LDA integrated portable, intelligent and rapid detection system as trace water indicator and cyanide detector

Portable, rapid, accurate and on-site detection of analysis target has always been the goal of continuous efforts in the field of analysis. In this work, a novel intelligent and rapid detection system based on an AIE dye (TPA-DCV) was established for portable and on-site detection of trace water in organic solvents and CN? in water by integrating the smartphone and linear discriminant analysis (LDA). The TPA-DCV displayed remarkable solvatochromism effect and showed different fluorescence colors to different water contents of different solvents, with the minimum detection limit of 54 ppm. In addition, TPA-DCV also exhibited specific response to CN?, and showed significant fluorescence changes to different amounts of CN?. With the assist of this detection system, these different fluorescence color signals could be accurately classified in canonical score plot. What's more, the classification and distribution of fluorescence color in canonical score plot showed regular change with the target concentration, which could be used to quantify the trace water and CN?. The rationality and practicability of this detection system were preliminary verified by a large number of real sample analyses. This detection system greatly simplifies the analysis process, which is in the proof of intelligent and rapid detection just using a simple color analysis without any instrument test, which may be a big step forward.

Highly selective flurogenic chemosensor for cyanide ion in aqueous medium and its applications of logic gate and Hela cells

We have successfully synthesized triphenylamine-based fluorophores (MK and HK) with cyanoacrylic acid as a receptor for CN– ion sensing in a 99% aqueous medium. From the emission titration spectra, the detection limit of cyanide ion calculated towards MK and HK, respectively, are 234 nM and 11 nM. The observed binding constants for MK and HK, respectively, are 27 × 10-3 M and 10 X 10-2 M. The plausible sensing mechanism is confirmed by various methods such as Job's plot experiment, proton NMR titration, and density functional theory. Furthermore, the prominent application is the naked-eye detection of cyanide from non-fluorescent to greenish-yellow fluorescent under 365 nm UV light. Based on the observed data from fluorescence spectroscopic studies, a new logic circuit is designed. Moreover, the potential application of HK and MK in the Hela cell line exhibited turn on fluorescence image for cyanide ion through the inhibition of the ICT process. In addition to that, the probe MK and HK is successfully applied in the analysis of the real sample for the rapid detection of cyanide ions.

Acid-induced tunable white light emission based on triphenylamine derivatives

A series of triphenylamine (TPA) derivatives with various substituent groups were prepared and showed different absorption and fluorescence characteristics due to the substituent effect. On account of the existence of pyridine units, these TPA derivatives exhibited acid-induced tunable multicolor fluorescence emission including white light emission. In addition, acid-induced fluorescence regulation of these compounds has been also realized in the solid state, which enable them to be successfully constructed the stimuli-responsive fluorescent films and fluorescent inks for inkjet printing.

Axial-symmetric conjugated group promoting intramolecular charge transfer performances of triphenylamine sensitizers for dye-sensitized solar cells

The intramolecular charge transport (ICT) process directly determines the charge generation, transport, and even injection of the dye-sensitized solar cell (DSSC) sensitizer. Herein, we constructed a new series of D-π-A system by linking 4-methoxyphenyl and triphenylamine donors with an ethynyl group having an axial-symmetric conjugated system. Since the axisymmetric conjugate group overcomes the reduction of the conjugate characteristic caused by the plane distortion, the molecular ICT performance and the electronic recombination inhibition are effectively improved. As a result, the photoelectric conversion efficiency was increased from 3.43% to 6.37% by means of the extension of the π-bridge at same time. It provides a new idea for the design and development of DSSC sensitizers in the future.

New ferrocenyl-containing organic hole-transporting materials for perovskite solar cells in regular (n-i-p) and inverted (p-i-n) architectures

Three triphenylamine derivatives containing ferrocenyl groups (JW6, JW7 and JW8) were synthesized by facile syntheses. Their HOMO levels match the valence band energy of CH3NH3PbI3. The introduction of ferrocenyl was aimed to obtain hole transporting materials with high mobility for perovskite solar cells. JW7 shows higher hole mobility (4.2 × 10?4 cm2 V?1 s?1) than JW6 (1.3 × 10?4 cm2 V?1 s?1) and JW8 (1.5 × 10?4 cm2 V?1 s?1). Their film-forming properties are affected by their molecule structures. The methoxyl and N,N-dimethyl terminal substituents of JW7 and JW8 are beneficial for having better solubility than JW6. The regular mesoporous TiO2-based perovskite solar cells (n-i-p) and the inverted planar heterojunction perovskite solar cells (p-i-n) fabricated using JW7 show the highest power conversion efficiency of 9.36% and 11.43% under 100 mW cm?2 AM1.5G solar illumination. For p-i-n cells, the standard HTM PEDOT-based cell reaches an efficiency of 12.86% under the same conditions.
