Abstract
A charge-transfer salt formed from a material comprising a repeat unit of formula (I) and an n-dopant: wherein BG is a backbone group of the repeat unit; R1 is a ionic substituent comprising at least one cationic or anionic group; n is at least 1; R2 is a non-ionic substituent; and m is 0 or a positive integer; the material further comprising a counterion balancing the charge of the cationic or anionic group.
