Abstract
A conjugated azopolymer and methods for making same. The azopolymer includes a plurality of monomer units containing isoindigo with R1 and R2 substituent groups, wherein R1 can be one or more C1 to 30 hydrocarbons; and R2 can be H or F. The azopolymer can have a number average molecular weight (Mn) of 4 to 20 kDa; a weight average molecular weight (Mw) of 12 to 50 kDa; and a poly dispersity index (PDI) of 2 to 3. The polymer can further have selected maximal wavelengths (λmax) of 481 to 709 nm and electrochemical reduction events of −0.4 to −1.0 V against an Ag/AgCl reference electrode.
