Oligothiophenes as pendant groups grafted to polymer backbones... 

Similar polyvinyl polymers 2.43 containing pendant oiigothiophenes were prepared via radical polymerization. In this series, the oligothiophene moieties were endowed with an alkyl substituent at the other terminal position (Chart 1.9) [106], Self-assembly-induced white photoluminescence (400-700 nm range) was reported possibly due to intra- and inter-chain interaction of oligothiophenes which form a type of supramolecular arrangement suitable for charge transport in the device. 

An oligothiophene-flillerene pentad 2.116 (Chart 1.23) was recently synthesized, in which four pendant fullerenes are coupled to the two termini of long oligothiophene chains [223]. An efficient intramolecular electron transfer process was observed in the excited state for these pentads. In a sandwich device Al/2.116 (n = 6)/Au, a photocurrent generation of 14 % was reported under monochromatic illumination, which is similar to the value for triad 2.115 (n = 3).
