A novel conjugated polymer, TdTB, having an alternating configuration of electron donor and acceptor was synthesized for organic photovoltaic (OPV) application. Intramolecular charge transfer made TdTB exhibit bimodal-shaped absorption in visible region, which secured about 4% power conversion efficiency (PCE) via enhanced absorption efficiency. OPV cells could be further optimized by means of additive-assisted...
A new phthalonitrile derivative (3), bearing 2-(4-methyl-1,3-thiazol-5-yl) ethoxy- and chloro-substituents at peripheral positions, was synthesized in this work. Cyclotetramerization of (3) in 1-hexanol gave the desired metallophthalocyanines (4–6). All of the synthesized compounds have been characterized by using elemental analysis, UV–vis, FT-IR, 1H NMR and MS spectroscopic data. Aggregation behaviors...
