摘要

•Benzofulvene derivatives 6-Pyr-BF3k and 6-PTPC-BF3k bearing uncomplexed and complexed pyridine rings are synthesized.•The solvent removal from a 6-Pyr-BF3k solution leads to the spontaneous formation of the homopolymer poly-6-Pyr-BF3k.•The same procedure applied to the 6-PTPC-BF3k monomer highlights the competition between polymerization and crystallization.•Uncomplexd poly-6-Pyr-BF3k show interesting emission properties, while poly-6-PTPC-BF3k shows low emission quantum yield.
