A novel tetraphenylethylene derivative: 4-methyl-N-[3-(1,2,2-triphenylethenyl)phenyl]benzenesulfonamide with aggregation-induced emission

Abstract

The novel tetraphenylethylene derivative 4-methyl-N-[3-(1,2,2-triphenylethenyl)phenyl]benzenesulfonamide (abbreviated as MTBF), C 33 H 27 NO 2 S, was synthesized successfully and characterized by single-crystal X-ray diffraction, highresolution mass spectroscopy and 1 H NMR spectroscopy. MTBF crystallizes in the centrosymmetric monoclinic space group P2 1 /c. In the crystal structure, the MTBF molecules are connected into a one-dimensional band and then a twodimensional sheet by hydrogen bonds of the N-HÁ Á ÁO and C-HÁ Á ÁO types. The sheets are further linked to produce a three-dimensional network via C-HÁ Á Á interactions. The molecules aggregate via these intermolecular forces, which restrain the intramolecular motions (RIM) and decrease the energy loss in the aggregation state, so as to open the radiative channels, and thus MTBF exhibits excellent fluorescence by aggregation-induced emission (AIE) enhancement. research papers Acta Cryst.

Comparative Analysis of Proton Conductivity in Two Zn-Based MOFs Featuring Sulfate and Sulfonate Functional Groups

“…To further illustrate and quantify the hydrogen bonding interactions in the crystal structures, Hirshfeld surface analysis of MOF- 1 and MOF- 2 was performed using the CrystalExplorer software. , Hirshfeld surfaces mapped with d norm for structures of MOF- 1 and MOF- 2 are shown in Figure S5. The quantitative contribution of each interaction was obtained by resolving the d norm surface into a fingerprint map. , O···H/H···O mixture represented typical hydrogen bonding, and its relative contributions in MOF- 1 and MOF- 2 were 79.1 and 20.7%, respectively.…”
