Photophysical and electrochemical investigation of highly conjugated pyridine based diphenylamine materials

Three simple and small donor-acceptor type conjugated moieties, namely (2Z, 2′Z)-3,3'-((hexylazanediyl)bis (4,1-phenylene))bis (2-(pyridin-2-yl)acrylonitrile) (DPA-PA-1), (2Z, 2′Z)-3,3'-((dodecylazanediyl)bis (4,1-phenylene))bis (2-(pyridin-2-yl)acrylonit

A highly efficient magnetic solid acid nanocatalyst for the synthesis of new bulky heterocyclic compounds

Fe3O4 nanoparticles were prepared and coated with 3-aminopropyltriethoxysilane (APTES). The formed amine-surfaced Fe3O4@APTES NPs were further chemically modified with maleic anhydride (MAH) to generate Fe3O4@APTES·MAH NPs. This catalyst was characterized by FT-IR, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TG), energy dispersive X-ray analyzer (EDAX), vibrating sample magnetometry (VSM) and the dynamic light scattering (DLS) measurement technique. The catalyst showed high thermal stability and good reusability. Some new bulky heterocyclic compounds such as bis(2,4,5-triarylimidazole), bis(1,4-dihydropyridine), bis(1,8-dioxooctahydroxanthene) and bis(1,8-dioxo-decahydroacridine) derivatives were synthesized using 4,4′-(alkylazanediyl)dibenzaldehyde as substrate and Fe3O4@APTES or Fe3O4@APTES·MAH as catalyst. The high purity products were isolated and the catalyst was easily separated with a simple work-up with magnetic field and was recycled several times without noticeable loss of reactivity under the described reaction conditions.

Bi-anchoring organic sensitizers of type D-(π-A)2 comprising thiophene-2-acetonitrile as π-spacer and malonic acid as electron acceptor for dye sensitized solar cell applications

Two new bi-anchoring organic sensitizers of type D-(π-A)2 comprising the identical π-spacer (thiophene-2-acetonitrile) and electron acceptor (malonic acid) but different aryl amine as electron donors (diphenylamine and carbazole) were synthesized, characterized and fabricated metal free dye-sensitized solar cell devices. The intra molecular charge transfer property and electrochemical property of these dyes were investigated by molecular absorption, emission, cyclic voltammetric experiments and in addition, quantum chemical calculation studies were performed to provide sufficient driving force for the electron injection into the conduction band of TiO2 which leads to efficient charge collection. Among the fabricated devices, carbazole based device exhibits high current conversion efficiency (η = 4.7%) with a short circuit current density (JSC) 15.3 mA/cm2, an open circuit photo voltage (VOC) of 0.59 V and a fill factor of 0.44 under AM 1.5 illumination (85 mW/cm2) compared to diphenylamine based device.

Synthesis of bianchored metal free organic dyes for dye sensitized solar cells

Two bianchored metal free organic dyes (Car-th-CN and Dpa-th-CN) were designed and synthesized for DSSC application, in which carbazole or diphenylamine moieties were used as the donor, cyano vinyl thiophene unit as the π-bridge and cyanoacrylic acid group as the electron acceptor. The structures of the synthesized dyes were confirmed by NMR, HR-Mass and elemental analysis. The optical, electrochemical, theoretical and photovoltaic properties of the synthesized dyes were investigated. Fabricated photovoltaic devices based on carbazole unit as a donor (Car-th-CN) showed a maximum current conversion efficiency of 4.04% under AM 1.5 illumination (85 mW cm-2) and monochromatic incident photon to current efficiency (IPCE) of 38.1%. The reason for the higher efficiency of Car-th-CN is due to the planar nature of carbazole moiety and hence increases the capability of adsorbed dye amount and electron lifetime in TiO2 surface.

Synthesis of D-(π-A)2 organic chromophores for dye-sensitized solar cells

New bi-anchoring donor-π-acceptor (D-π-A) metal-free organic dyes based on diphenylamine, carbazole as donor, cyano vinyl biphenyl as a π-linker and cyanoacrylic acid, rhodanine-3-acetic acid as acceptor/anchor are synthesized, characterized and used for the dye-sensitized solar cell (DSSC) applications. Among the fabricated DSSCs, device based on the carbazole as donor, cyano vinyl biphenyl as a π-linker and cyanoacrylic acid as acceptor exhibits a high power conversion efficiency of 2.37% with a short-circuit current density of 5.18 mAcm-2, an open-circuit photo voltage of 0.766 V and a fill factor of 50.8% under AM1.5 illumination (85 mWcm -2) compared to other devices.

Synthesis of novel diphenylamine-based fluorescent styryl colorants and study of their thermal, photophysical, and electrochemical properties

Three novel "Y"-shaped acceptor-π-donor-π-acceptor-type compounds were synthesized from 4,4′-(hexylimino)bis(benzaldehyde) as a donor and 2-methylthiazolo[4,5-b]quinoxaline derivatives as strong electron acceptors condensed by classical Knoevenagel condensation. Their absorption, emission, and thermal properties and electrochemical stability were investigated. It was found that the strong electron acceptor-donor chromophoric system of these compounds showed high Stokes shift, excellent thermal stability, and electrochemical reversibility. The solvatochromic behavior of these colorants was studied by using various solvents such as toluene, chloroform, ethyl acetate, tetrahydrofuran, methanol, and N,N-dimethylformamide in increasing order of polarity. The dyes were characterized by means of elemental analysis, 1H NMR, and mass spectrometry. Springer-Verlag 2010.

1456-1459 synthesis of diphenylamine-based novel fluorescent styryl colorants by knoevenagel condensation using a conventional method, biocatalyst, and deep eutectic solvent

(Figure Presented) Novel Y-shaped acceptor-π-donor-π-acceptor-type compounds, synthesized from 4,4'-hexyliminobisbenzaldehyde as electron donors and different active methylene compounds as electron acceptors, were produced by conventional Knoevenagel condensation alone, with a deep eutectic solvent, or with a lipase blocatalyst to compare the yield and recyclability among the three methods. Yield, reaction time, reaction temperature, and recyclability were compared among the three methods. The photophysical properties and thermal stability of the products were also investigated.
