Thiophene-based trimers is a new class of organic electronic molecular units, which enable the organization and polymerization of conjugated structures within living biological systems and inside operating electronic devices and systems. The trimers can be equipped with side groups that targets and promotes coupling to specific surfaces and (bio-)chemical cues making self-organization and -assembly of organic bioelectronics possible in a novel manner. The chemical and physical fundamentals of the trimers, the route of polymerization, and their performance while operating in neuromorphic and in vivo-manufactured bioelectronics will be reported. Specifically, neuromorphic systems based on organic electrochemical transistors including the trimers will be described along with bioelectronic systems formed inside living plants, cells and animal models. Our findings promise for radically new ways of forming bioelectronic systems in living systems, which mimicks the structures and functions of the signaling of biology.
