Synthesis of 2,6-diiodo-4,4-ethylenedioxy-4H-cyclopenta-[2,1-b:3,4-b′]dithiophene and conjugated copolymers on its basis
摘要:
New synthesised conjugated copolymers based on 4H-cyclopenta[2,1-b:3,4-b']dithiophene exhibit the absorption of light in the red spectral region with the maximum at 580-590 nm and optical bandgaps of 1.85-1.88 eV. Organic photovoltaic cells prepared from composites of these copolymers with [6,6]-phenyl-C-61-butyric acid methyl ester (PCBM) showed the efficiency up to 0.5%.
