Synthesis and characterization of aniline and thiophene and/or alkylthiophenes polymers

Autor: María Angélica del Valle, F. R. Diaz, María Angélica Pardo

Publikováno v: Polymer Bulletin. 72:2189-2199

Three new polymers, obtained by reacting thiophene or 3-alkylthiophenes as electron donors with aniline as acceptor in a donor–acceptor structure, were synthesized via oxidative polymerization using iron(III) chloride (FeCl3). The final products we

A successful approach to improve organic photovoltaic cell performance is the introduction of a thin layer called the electron-blocking layer (EBL) at the interface organic material/cathode. Here, the effect of the EBL is discussed through the use of
