The integration of next-generation electronics into society is rapidly reshaping our daily interactions and lifestyles, revolutionizing communication engagement with the world. Future promise stimuli-responsive features enhanced biocompatibility, such as skin-like health monitors sensors embedded in food packaging, transforming healthcare reducing waste. Imparting degradability may reduce adverse environmental impact lead to opportunities for monitoring. While advancements have been made producing degradable materials encapsulants, substrates, dielectrics, availability conducting semiconducting remains restricted. π-Conjugated polymers are promising candidates development conductors or semiconductors due ability tune their stimuli-responsiveness, mechanical durability. This perspective highlights three design considerations: selection π-conjugated monomers, synthetic coupling strategies, degradation polymers, generating electronics.

The polymers P1 and P2, with structures diketopyrrolopyrrole (DPP)-πbridge-3,4,-ethylenedioxythiophene (EDOT)-πbridge [πbridge = 2,5-thienyl πbridge 2,5-thiazolyl P2] are selected as N2200 (a known naphthalenediimide-dithiophene semiconductor) polymer.
