ABSTRACT Luminescent probes attract increasing attentions for the unique superiorities like visually real‐time detecting. However, optical humidity sensing, it is still quite challenging to attain facile dehydration/activation in sensing materials, due high polarity of water molecules, which limits their applications detection and energy‐conserving applications.

Comprehensive Summary The advancement of multifunctional fluorescent probes for monitoring diverse environmental parameters is paramount importance. In this study, we engineered dual‐chromophore probe, DBT , that responds to multiple stimuli by integrating functional groups with unique characteristics. Notably, the probe exhibits pronounced bimodal emission under specific conditions, its fluorescence shifting between red and blue in response alterations solvent composition, humidity levels, temperature variations. Significantly, facilitates differentiation visual identification eight solvents, permits quantitative detection trace water content organic solvents. Additionally, it allows gasoline. These findings herald development single‐molecule materials capable responding stimulus, paving way simultaneous multi‐stimuli discrimination various applications.

Charge transfer (CT) complexes formed by donor–acceptor (D-A) pairs play a critical role in organic optoelectronic devices, where the CT effect is highly correlated with molecular packing and intermolecular interaction. There are still challenges exploring mechanisms of charge noncrystal state. Most studies regulated altering π-conjugated backbone substituents, which would lead to some uncertainties packing-property relationship. Herein, we utilized triazatruxene (TAT) different alkyls as donors 1,3,5-benzenetricarbonitrile (TCNPh) derivatives acceptors. The systems complex were constructed simply grinding mixture study arrangement transfer, an obvious odd–even could be observed. Thus, our further enriched alkyl chain regulation, allowing for more profound understanding relationship among aggregation structures, interactions, characteristics complex.

Abstract Chiral self‐discrimination plays a critical role in supramolecular chemistry and materials science. However, an ideal strategy for achieving chiral remains elusive due to the inevitable nonspecific binding of incorrect enantiomers, insufficient intrinsic optical activity molecules. Herein, novel 1,1′‐binaphthol (BINOL) derivative with imide group fused at peri ‐position one naphthol scaffold is developed, which combines dual functionalities aggregation‐induced emission characteristic BINOLs, high 1,8‐naphthalimides. The multiple molecular recognition between two hydroxyl groups BINOL units carbonyl 1,8‐naphthalimide moieties endows precise behaviors. As expected, homochiral aggregates exhibit reversible phase transitions, switching from non‐emission bright green upon absorption desorption methanol vapor. In contrast, heterochiral conglomerates irreversible yellow changes impact self‐discrimination. Such self‐discrimination‐induced luminescence vapochromism can be further applied high‐level anti‐counterfeiting data encryption. This work provides new perspective on smart organic based

Stimuli-responsive organic luminescent crystals have attracted significant attention in recent years for their potential sensor and memory applications. While turn-on luminescence is superior detection sensitivity compared with turn-off luminescence, the development of that exhibit response to multiple stimuli remains a challenge. Herein, chiral bisimidazolyl 1,1'-bi-2-naphthol (BINOL) dimethyl ether exhibited dual-stimuli-responsive based on two distinct mechanisms. In crystalline state, was substantially quenched by intermolecular hydrogen bonds between imidazole rings.
