Electronic and photo-active polymers as a class of advanced materials have attracted a lot of interest during last two decades. Typically these materials are synthesized chemically or electrochemically under harsh conditions such as extremely low pH, toxic catalysts and byproducts. New enzymatic approaches have been developed for the synthesis of electro and photo active polymers such as polyanilines, polyazophenols, and polypyrene derivatives. These enzymatically synthesized materials show interesting optical and electronic properties.
