“…[42] Building upon the energy level formula, the calculated optical band gaps of compounds T2 and T3 can be obtained as 3.79 eV and 3.76 eV, respectively, which underscore their heightened charge transfer capability in excited states compared to compound T1 (3.65 eV). [43] From a theoretical standpoint, it's important to highlight that compound T3 exhibits a highly distorted molecular packing. This distortion effectively impedes direct molecular stacking and robust intermolecular interactions, promoting a looser arrangement and rendering it conspicuously responsive to mechanical force-induced fluorescence.…”

In this study, we have successfully designed and synthesized two novel dual‐emission emitters featuring phenothiazine‐5‐oxide and phenothiazine‐5,5‐dioxide motifs, characterized by highly lopsided and asymmetric conformational states. Through rigorous spectral examinations and DFT calculations, the compounds exhibit distinctive ICT phenomena, coupled with efficient emission in solid states and AIEE characteristics under high water fractions in DMF/H2O mixtures. These non‐planar luminogens exhibit vibrant green and blue solid‐state luminescence, with fluorescence quantum yields of 24.1% and 15.21%, respectively. Additionally, they both emit green fluorescence in THF solution, with notable emission quantum yields 36.4% and 30.4%. Comprehensive theoretical investigations unveil well‐defined electron cloud density separation between the energies of HOMO/LUMO levels within the two luminogens. Notably, the targeted molecule harboring the phenothiazine‐S,S‐dioxide motif also demonstrates remarkable reversible mechanofluorochromic properties. Moreover, we testify their potential in applications such as solid‐state rewritable information storage and live‐cell imaging in solution states. Through theoretical calculations and comparative studies, we have explored the intrinsic relationship between molecular structure and performance, effectively screening and identifying new fluorescent molecules exhibiting outstanding luminescent attributes. These discoveries establish robust theoretical and technical foundation for the synthesis and application of efficient DSE‐based MFC materials, opening new avenues in the realm of advanced luminescent materials

An A‐π‐D‐π‐A type carbazole‐derived organic ligand was designed and synthesized, and an intriguing one‐dimensional metal‐organic tube possessing infinite tubular superstructure was successfully constructed and characterized. Inspiringly, it displayed fascinating stimuli‐responses including room‐temperature gasochromic luminescent response for volatile organic compounds and effective fluorescent quenching for nitroaromatic explosives. In particular, the capabilities of selectively detecting 2,4,6‐trinitrophenol showed great potential as a promising fluorescent sensor.
