Theoretical and experimental investigations on the photoconductivity and nonlinear optical properties of donor–acceptor π conjugated copolymer, poly(2,5-(3,4-ethylenedioxythiophene)-alt-2,7-(9,9-dioctylfluorene))

Abstract

A new donor–acceptor copolymer, poly(2,5-(3,4-ethylenedioxythiophene)-<italic>alt</italic>-2,7-(9,9-dioctylfluorene) copolymer with high optical limiting efficiency (0.47 GW cm⁻²) and photoconductivity (at 75 V μm⁻¹, the photosensitivity was 289 742).
