“…24,25 Moreover, the butterfly shaped PTZ structure enables the molecule to be twisted and display excellent luminescence, good photoconductivity, and reversible oxidation, thus, making it suitable for MFC applications. [26][27][28][29] Boron-containing materials have received considerable attention due to the intriguing electronic and photophysical performances with strong electron-accepting ability; thus, they are utilized for the development of next-generation organic optoelectronics. 30,31 However, a large number of organoboranes are extremely unstable in air and moisture, which has considerably hindered their applications in photoelectric devices; thus, improving their air/moisture stability is a very important research topic in this field.…”

Stimuli‐responsive crystalline materials have received much attention for being potential candidates of smart materials. However, the occurrence of polymorphism‐driven stimuli responses in crystalline materials remains interesting but rare. Herein, three polymorphs of an acylhydrazone derivative, N'‐[(E)‐(1‐benzofuran‐2‐yl) methylidene] pyridine ‐4‐carbohydrazide (BFMP) were prepared. Form‐1 undergoes a photomechanical response via E→Z photoisomerization under UV irradiation, accompanied by a decrease in fluorescence intensity and a change from colorless to yellow. Two types of Z→E thermal isomerization mechanisms with significant differences in conversion rate were observed at different temperatures in form‐1. The solid‐melt‐solid transition has a faster conversion rate compared to the solid‐solid transition due to freedom from lattice confinement. The transition from form‐2 to form‐3 can be achieved under grinding, coupled with a significant decrease in fluorescence intensity. The similar molecular stacking pattern of form‐2 and form‐3 provides a structural basis for the grinding‐induced crystalline transition behavior. In addition, the presence of the pyridine moiety imparts an acid chromic property. The combination of photochromism and acid chromism explores the possible applications of acylhydrazone derivatives in information encryption.
