Abstract
Emission color changes of 4-[bis(4-methylphenyl)amino]benzylideneaniline (BMBZA) and 4-[bis(9,9-dimethylfluoren-2-yl)amino]benzylideneaniline (BFBZA) in response to hydrochloric acid (HCl) vapor and solid organic acids, pentafluorobenzoic acid (PFBA) and benzoic acid (BA), have been investigated in their different solid states. Emission color of BMBZA crystals changed from greenish blue to reddish orange by exposure to HCl vapor, whereas the emission color of BFBZA crystals did not. However, powder sample obtained by grinding the BFBZA crystal exhibited emission color change by exposure to HCl vapor. Similar results of emission color changes of BMBZA and BFBZA crystals in response to PFBA were obtained. In the case of BMBZA–BA and BFBZA–BA systems, grinding of the crystalline mixtures allowed their emission color changes without change in their object colors.
