Communication: Bismaleimides having electron-donating diphenylmethylamine or triphenylamine moieties (A((=))-D-(*)-A((=))), as well as their saturated model compounds were synthesized. Their fluorescence structural self-quenching effect (SSQE). On the basis of this strong SSQE of A((=))-D-(*)-A((=)) bismaleimides, a new fluorescence approach can be developed to monitor the curing process in bismaleimide resins, which is in agreement with the results from FT-IR and H-1 NMR analyses.
