AIE-active non-planar phenothiazine-based derivatives with mechanical-induced emission enhancement characteristics

Abstract

Two new mechanofluorochromic-active AIE non-planar phenothiazine-based dyes (E)-N'-((10-ethyl-10H-phenothiazin-3-yl)methylene)-4-methylbenzenesulfonohydrazide (EPMMBS) and (E)-N'-((10-ethyl-10H-phenothiazin-3-yl)methylene) benzenesulfonohydrazide (EPMBS) were designed and successfully fabricated by simple one step aldimine condensation reaction strategy. The synthesized compounds EPMBS...

Multiresponsive luminescent sensing behaviour of a tetraimidazole ligand and its 3D Cd(ii) metal–organic frameworks

“…S7a,† the methanol solution of timpb exhibits one slightly broad absorption band at 230 nm, while the DCM solution of timpb displays one intense sharp absorption band at 238 nm, which shows the electronic charge transfer between the timpb and solvent molecules. 31 timpb in methanol or DCM solutions shows similar emission bands of 316 nm upon excitation at 275 nm. Further, the sensing behaviour of timpb towards different solvent molecules such as ethanol, methanol, DMA, DMF, and acetonitrile was also examined employing fluorescence spectroscopy.…”
