Conjugated Inorganic–Organic Hybrid Polymers with p‐Block Elements

Angewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
The influence of various p‐block element motifs on the photophysical properties of conjugated inorganic‐organic hybrid polymers is surveyed regarding applications in organic electronics. Recent advances in the use of heavier elements as well as heavier multiple bonds and the development of diverse (post‐)functionalization strategies suggest ample scope
