a Optical microscope images showing the cocrystal-to-polycrystal transformation under room light (left) and 365 nm UV irradiation (right). Top: the initial AOTC cocrystals; bottom: the transformed AOTC+NEt3 crystals. b Partial 1H NMR spectra of the initial AOTC cocrystal and the transformed AOTC+NEt3 crystal (DMSO-d6, 500 MHz). c Molecular structures of the single crystals of AOTC, AIC, and ACTC. d FTIR spectra of AIC, ACTC, AOTC+NEt3, and AOTC. e PXRD patterns of AIC, ACTC, AOTC+NEt3, and AOTC. f Solid-state fluorescence spectra of AOTC+NEt3, ACTC, and AIC.
