Abstract

Through-space charge-transfer polybenzonorbornenes, consisting of a carbazole donor and dimesitylboron acceptor in the ortho-positions of phenyl units on the benzonorbornene repeating unit, have been developed, revealing efficient thermally activated delayed fluorescence emission and full-colorpiezochromism.
