4-(4-Chlorophenyl)-5-(4-nitrophenyl)-3-phenyl-4H-1,2,4-triazole

Acta Crystallographica Section E, 2008
The title compound, C20H13ClN4O2, was synthesized by the condensation of 4-nitrobenzohydrazide and N-(4-chlorophenyl)benzimidoyl chloride in N,N-dimethylacetamide. The asymmetric unit contains two independent molecules. In one molecule, the triazole ring

Hyperspectral Fluorescence Imaging with a New Polarity‐Ultrasensitive Fluorescent Probe

Advanced Science, EarlyView.
Based on the critical role of the π‐spacer in determining wavelength sensitivity to microenvironmental polarity, a new fluorescent probe, Lipi‐PS is rationally developed, which exhibits the highest polarity‐sensitivity so far. Its integration with hyperspectral fluorescence imaging enables multiscale polarity mapping across cells, tissues, and ...

2,3-Bis(4-bromophenyl)quinoxaline

Acta Crystallographica Section E, 2008
The title compound, C20H12Br2N2, was prepared by the reaction of 1-(3-bromophenyl)-2-(4-bromophenyl)ethane-1,2-dione with o-phenylenediamine in refluxing ethanol. In the molecule, all bond lengths and angles are within normal ranges.

Achieving Highly Roust Polymeric Microspheres with Efficient and Full‐Color Organic Afterglow for 3D Printing and Anti‐Counterfeiting

Advanced Science, EarlyView.
Highly robust polymeric microspheres with efficient ultralong organic phosphorescence, dual‐mode organic afterglow, and persistent fluorescence are developed by embedding different organic luminogens into melamine‐formaldehyde polymer matrices. Their organic afterglow quantum yields and lifetimes are up to 18.0% and 1.39 s under ambient conditions ...

Crystal structure of methyl (2Z)-2-{[N-(2-formylphenyl)-4-methylbenzenesulfonamido]methyl}-3-(4-methoxyphenyl)prop-2-enoate

Acta Crystallographica Section E: Crystallographic Communications, 2015
In the title compound, C26H25NO6S, the S atom shows a distorted tetrahedral geometry, with O—S—O [119.46 (9)°] and N—S—C [107.16 (7)°] angles deviating from ideal tetrahedral values, a fact attributed to the Thorpe–Ingold effect.

Excitation‐Dependent Quadruple‐Level Emission from an Isolated Molecule for Dynamic Information Encryption

Advanced Science, EarlyView.
By manipulating the quadruple decoupled radiative transitions of donor and acceptor units, dual‐phase excitation‐dependent afterglow emission is achieved for the first time in a single isolated molecule. The decoupled donor‐acceptor units precisely manipulate the electron transfer pathways in ACRSP, endowing it with intrinsic single‐molecule Ex‐De ...
