Spontaneous amino-yne click polymerization enabled by pyridinium-activated alkynes toward p-π conjugated ionic polymers.

ABSTRACT: The p-π conjugated polymers have garnered considerable interest owing to their distinctive electronic structures, which arise from the interaction between p orbitals and π electrons. Currently, the p-π conjugated polymers with charged side chains have been extensively studied, those featuring charged backbones are rare due to the synthetic difficulties. In this work, we developed a spontaneous amino-yne click polymerization utilizing pyridinium-activated alkyne and aromatic primary amine monomers, enabling the efficient synthesis of p-π conjugated ionic polymers with high weight-average molecular weights (M _w, up to 44 100) and excellent yields (up to 98%). The resultant polymers are emissive, but demonstrate remarkable photothermal properties. Upon irradiation with an 80
