| Abstract: | "The reaction of CF(3)COOAg, 3-bdppmapy (N,N-bis(diphenylphosphanylmethyl)-3-aminopyridine) and HTZ (1,2,4-triazole-3-thiol) in CH(2)Cl(2)/MeOH resulted in a dinuclear Ag/P/S complex [Ag(2)(TZ)(2)(3-bdppmapy)(2)].xSol (1.xSol). Crystals of 1.xSol converted to 1.2MeOH in air at room temperature and further to 1 under vacuum upon heating. The solid-state, room-temperature photoluminescent emission of 1.xSol (510 nm) shifted to 494 nm (1.2MeOH) and 486 nm (1). Grinding solids of 1.2MeOH in air resulted in amorphous 1G characterized by solid-state emission at 468 nm, which converted to 1GR with 513 nm emission upon MeOH treatment. Grinding 1GR in air returned 1G, and this interconversion was reproducible over five cycles. The solid-state photoluminescence of 1G changed in response to vapors containing low-molecular weight alcohols but remained unchanged after exposure to other volatile organic compounds (VOCs) or to water vapor. Test papers impregnated with 1G could detect methanol in vapors from aqueous solutions at concentrations above 50%. Complex 1G is, therefore, an example of a stimuli-responsive molecular sensor for the detection of alcohols" |
