Abstract
A method of fabricating a conjugated polymer may include alkylating a carbazole with an alkyl bromide, in a solvent mixture, to form an alkyl carbazole; brominating the alkyl carbazole to form an N-alkyldibromocarbazole; and reacting the N-alkyldibromocarbazole with a distanyl-biselenophene in the presence of a catalyst to form a conjugated polymer having repeating units of formula (5)
