The field of supramolecular polymers is rapidly expanding; however, the exploitation these systems as functional materials still elusive. To become competitive, must display microstructural order and emergence new properties upon copolymerization. tackle this, a greater understanding relationship between monomers' design polymer microstructure required well set monomers that efficiently interact with one another to synergistically generate Here, we present first implementation frustrated Lewis pairs into copolymers. Two copolymers based on π-conjugated O-bridged triphenylborane two different triphenylamines formation B–N within chain. remarkably long lifetime circularly polarized nature resulting photoluminescence emission highlight possibility obtain an intermolecular charge transfer. These results are proposed be consequences enchainment 1D aggregates. Although it challenging precise molecular picture copolymer microstructure, random blocklike could deduced from combination optical spectroscopic techniques theoretical simulation.
