Bismaleimides having electron‐donating diphenylmethylamine or triphenylamine moieties (A (=) ‐D (*) ‐A (=) ), as well as their saturated model compounds were synthesized. Their fluorescence behavior was found to show a strong 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 1 H NMR analyses.
