Comprehensive Summary Stimuli‐responsive organic luminescent materials exhibit significant sensitivity to various external stimuli, among which their excellent photosensitivity is particularly prominent. This unique feature gives them great potential for applications. Herein, five small molecule emitters based on triphenylamine derivatives have been synthesized via Suzuki‐coupling reaction. These molecules fluorescence properties with quantum yields ( Φ ) all reaching over 90%. When irradiated a 365 nm UV lamp, interesting photochromic phenomena occurred in chloroform solutions. phenomenon has studied intensively by UV‐vis absorption and spectroscopy, EPR measurements, density functional theory calculations, finally, the group was used as photoinitiation precursor electron donor, photo‐induced charge transfer complex (PCTC) initiated donor successfully constructed.

Altering the manner in which groups are connected could offer a straightforward approach to achieving different functionality. Herein, heterotetraarylene molecules with varying bond‐linked quinoline moieties synthesized and designed investigate their differential performances. The carbon‐carbon double bonded quinolines exhibits multifunctional properties: 1) all‐visible light‐induced photochromism, 2) acidochromism, 3) acid–base gated photoswitch. Simultaneously, it achieves dual‐mode fluorescence modulation through both photoexcitation acid/base stimuli. However, by carbon single bonds exhibit divergent properties, including emission enhancement solvent‐dependent emission. This bond‐selective functional divergence enables precise customization of stimulus‐responsive simple connectivity control, establishing novel design paradigm for smart molecular systems. Furthermore, heterotetraarylene‐linked many thus allowing construction new dual‐responsive encryption system.

Abstract Cholesteric liquid crystals (CLCs), as photonic materials with unique temperature responsiveness, show great potential in smart optical applications. However, traditional CLC exhibit limitations self‐supporting properties and photoaddressing regulation of thermochromism. Here, dual‐wavelength responsive donor–acceptor Stenhouse adducts (DASAs) are incorporated to construct a sophisticated dual‐mode system for thermochromic polymer dispersed cholesteric (PDCLCs), wherein CLCs droplet form film. This research demonstrates both the reversible photoswitching irreversible Ultraviolet‐induced degradation DASAs can precisely regulate phase PDCLCs while maintaining Bragg reflection throughout visible spectrum. Based on these characteristics, novel temperature‐resolved is designed fabricating anti‐counterfeiting labels, including erasable disposable permanent temperature‐dependent storage indicators. Significantly, synergistic interaction between DASA's absorption PDCLC's achieves distinctive “flickering” effect (dynamic transitions: visible‐invisible‐visible) display. Moreover, enables dual‐photoaddressing encryption secret key within narrow window, creating “read‐and‐destroy” encryption. study presents photoregulation strategy multi‐mode display technology simple preparation convenient readout, paving new ways applications advanced information
