All-Conjugated Donor-Acceptor Block Copolymers featuring a Penta-fulvenyl-Polyisocyanide-Acceptor

Abstract

We report a fulvenyl-functionalized poly¬iso¬cyanide (PIC2) with a high electron mobility of μe = 10-2 cm2*V-1s-1. PIC2 has been incor¬po¬rated into block-copolymers with either regioregular poly(3-dodecyl¬thio¬phene) (P3DT → P(3DT-b-IC2)) or regioregular polythiazole (PTzTHX → P(TzTHX-b-IC2)). Block copolymer batches with different block-sizes have been isolated and their properties have been studied. Fluorescence quenching in the solid state and transient absorption spectroscopy indicate energy transfer from the donor- to the acceptor block upon photo-excitation. Fabrication of proof-of-principle organic photo¬vol¬taic cells with P(3DT-b-IC2) gave cells with an open circuit voltage (VOC) of ca. 0.89 V. The aggregation behavior of P(3DT-b-IC2) from solution was also studied, which revealed self-assembly into discreet micro¬spheres of 1-8 μm diameter, with a size distribution of 1.72(±0.37) μm under optimized aggregation conditions.
