A novel emitting amorphous molecular material, 4-[bis(9,9-dimethylfluoren-2-yl)­amino]benzylideneaniline (BFBZA), was designed and synthesized. BFBZA provided moisture-sensitive hybrid film combined with benzoic acid (BA) that exhibited reversible change in emission color in response to moisture like as hybrid films of 4-[bis(4-methylpheyl)­amino]benzylideneaniline with pentafluorobenzoic acid (PFBA) and BA. On the other hand, another hybrid film of BFBZA combined with PFBA did not exhibit such reversible change in emission color. The balance of acidity level of organic acid and basicity level of the emitting amorphous molecular materials was suggested to play a role for exhibiting reversible change in emission color.
