A general complexation phenomenon between carbonyl-based polymers and the nitrogen-containing organic base of DBU was discovered, which is demonstrated by photoluminescence. The complexation could not only enhance the intrinsic emission of carbonyl groups but also induce a new long-wavelength clusteroluminescence corresponding to the through-space n‧‧‧π complex.
