The functionalized 3,4-alkylenedioxythiophene (ADOT+) monomers can be represented by a chemical formula (CRR)(CRR)(CRR)OCHS, wherein x=0 or 1; wherein each of R, R, R, R, R, and Ris independently selected from hydrogen, a hydrocarbyl moiety, and a heteroatom-containing functional group; and wherein at least one of R, R, R, R, R, and Rcomprises the heteroatom-containing functional group selected from an aldehyde, a maleimide, and their derivatives thereof. Also, disclosed herein are aldehyde derivatives represented by (ADOT-CH—NH)Y and a maleimide derivative represented by (ADOT-(CH)—N)Z where p=1-2 and each of Y and Z is a hydrocarbyl moiety or a biofunctional hydrocarbyl moiety. In an embodiment of the ADOT+ monomers, one of R, R, R, R, R, and Ris replaced by a direct bond to an amide group, an azide group, or an ester group of a biofunctional hydrocarbyl moiety. Also, disclosed herein are polymers and copolymers made therefrom.
