, p. 11238 - 11249 (2017)
Fluorene-cored dendrimers containing a triphenylamine chalcone unit at the periphery have been synthesized by divergent methodology using a click chemistry approach, and their photophysical and electrochemical properties have been investigated. All of the dendrimers exhibited quasireversible oxidation reduction signals in cyclic voltammetry. All of the dendrimers were used as additives in dye-sensitized solar cells (DSSCs), and the higher generation dendrimers exhibited better power conversion efficiency than the lower generation dendrimers in solar energy harvesting systems.

A new alternative functional copolymer, PFT, comprising of fluorene and triphenylamine units with a tunable -CHO group in the side chain was synthesized by the polycondensation of 4-[N,N-di(4-bromophenyl)amino]benzaldehyde with 9,9-dihexylfluorene-2,7-bis

Carrier mobility in organic thin films is a key parameter for devices that use molecules as selective contacts such as organic and perovskite solar cells. Herein, we describe the synthesis of a free base porphyrin symmetrically substituted with four meso-4-aminophenyl-N,N-bis(2′,4′-dimethoxy[1,1′-biphenyl]-4-yl) units and its metalloporphyrin. The electrochemical and photophysical properties for both porphyrins have been measured. The results show that the HOMO and LUMO energy levels are appropriate for use as hole transport materials (HTM) in solar cells. Moreover, measurements of the carrier mobility by using the space charge limited current (SCLC) method in organic thin films leads to a hole mobility value of 2.4 ± 0.5 × 10–5 cm2/V s and 8.0 ± 0.5 × 10–6 cm2/V s for the zinc porphyrin and the free base, respectively. Upon addition of chemical dopants, the mobility values increased to 8.8 ± 0.5 × 10–4 cm2/V s, for the zinc porphyrin, and 5.2 ± 0.5 × 10–4 cm2/V s for the free base porphyrin. These values are close to the reference molecule spiro-OMeTAD, which has a mobility value of 2.5 ± 0.5 × 10–4 cm2/V s measured under identical conditions.

White-light emission (WLE) from a single molecule is a highly desirable alternative to a complex mixture of complementary colour emitters, which suffers from poor stability and reproducibility for potential use in organic electronic devices and lighting a

A new triphenylamine based probe (TPA) for detection of the cyanide anion (CN?) was designed and synthesized. In aqueous solution, TPA showed rapid fluorescence response and excellent selectivity for CN? ions, and other anions did not affect the detection process. The probe displays a detection limit of 1.17 μM which is lower than the threshold (1.9 μM) regulated by the World Health Organization (WHO) for CN? ions in aqueous solution. The sensitivity and photophysical properties of TPA were investigated using UV–Vis spectrophotometry, fluorescence spectrofluorometry, and 1H NMR titration techniques. Density functional theory (DFT) calculations were carried out to better understand the relationship between the photophysical properties and the electronic structures of TPA and TPA-CN.
