The light-driven azabenzannulation of PDIs was adapted to develop the light-frozen dynamic covalent polymerization of BACDs, enabling the dynamic growth of poly-imines that are subsequently converted into kinetically locked conjugated polymers using visible light. This process avoids homocoupling defects, the use of toxic or precious metals, and additives beyond an acid catalyst, generating minimal waste. Considering that any aldehyde-decorated molecule can be polymerized along the BACDs, diverse electron-deficient or electron-rich functional co-monomers of interest have been successfully introduced into the polymer chains to obtain electron-deficient conjugated polymeric materials with tuneable optical band gaps and energy levels, illustrating a potential high-adaptability to various applications. The resulting BACD-based polymers absorb across the visible to NIR spectrum, combining outstanding thermal, electrochemical, and photostability with strong interchain electronic interactions observed even in solution. These properties position them as promising materials for charge and energy transport in organic electronics. Future work focusing on regioisomerically pure 1,6-and 1,7-BACD polymers could enhance intrachain communication and interchain interactions through improved crystallinity. The combination of metal-free synthesis, tunability, and excellent stability makes BACD polymers a highly attractive new class of ntype semiconductors. Their development addresses the organic electronics community's ongoing need for high-performance electron-deficient materials to complement the capabilities of p-type semiconductors.
