Optimized charge transport in N-substituted isatin-based acceptor–donor–acceptor small molecules by regulating the side chain length for solution-processable organic thin-film transistors

Abstract

A series of acceptor–donor–acceptor small molecules based on fused-ring as donor and N-substituted isatin with different side-chains (from methyl to n-decyl) as acceptors were synthesized for solution-processable organic thin-film transistors.
