Novel phosphorous triazatetrabenzocorrole (4) bearing non-peripheral octatrifluorobutoxy groups was successfully synthesized, with an aim to develop potential far-red sensitizer for dye sensitized solar cells. The dye was characterized by ¹H NMR, IR, mass, and UV-vis spectral techniques. It showed excellent solubility in majority of common organic solvents. Aggregation behavior of the dye 4 was investigated in several solvents with increasing dielectric constants. This dye-4 was found to be adsorbed on the nanoporous TiO2 via axial ligation. Further implication of structure of dye due to incorporation of CF3 group on the energy levels was evaluated by theoretical and experimental approaches. The intense far-red absorption of dye 4 including its excellent solubility and proper control of its energy levels makes it a promising candidate for its application as sensitizer in dye sensitized solar cells.

Styrenic dendrons functionalized with ferrocenyl and chloromethylsilyl termini were synthesized and polymerized by the AIBN-initiated radical polymerization procedure yielding a ferrocenyl dendronized polymer and a chloromethylsilyl dendronized polymer, respectively. The latter polymer was functionalized with ferrocenyl groups using “click” chemistry. The ferrocenyl dendronized polymers are soluble in common organic solvents such as tetrahydrofuran, dichloromethane, and chloroform. They show a reversible ferrocenyl wave in cyclic voltammetry (CV) and form derivatized Pt electrodes. Their sizes and shapes were examined by size exclusion chromatography (SEC), atomic force microscopy (AFM), dynamic light scattering (DLS) and DOSY 1H NMR spectroscopy. [ABSTRACT FROM AUTHOR]
