Turn-on exciplex fluorescence induced by complexation of nonfluorescent pentafluorinated dibenzoylmethanatoboron difluoride with benzene and its derivatives

Abstract

A new pentafluorinated derivative of (dibenzoylmethanato)boron difluoride (5F-DBMBF2) was synthesized and studied as an “off–on” fluorescent probe for benzene derivatives with a reversible detection capability.

Recent development of the fluorescence-based detection of volatile organic compounds: a mechanistic overview

“…21b(i)). 83 Commonly, difluoroboron moieties are well-recognized for their electron-accepting nature. In addition, the incorporation of a penta-fluorine substituted phenyl ring in place of a phenyl ring uplifted the deficit nature of the probe, which triggers the formation of a van der Waals interaction-based ground state complex between the probe and benzene derivatives (Fig.…”

Novel DBMBF2-BODIPY dyads connectedviaa flexible linker: synthesis and photophysical properties

“…This allows them to occupy a special place among optical materials, [49][50][51][52] materials with emission caused by aggregation, 53,54 mechanochromic materials, [55][56][57][58][59] components for solar cells, 60 and chemical sensors. 61 One of the most promising applications of DBMBF 2 derivatives is the detection of trace amounts of vapours of benzene, toluene, and xylenes (BTX). [61][62][63][64][65][66][67][68][69][70][71][72] Despite the fact that DBMBF 2 derivatives have been well studied to date, there is almost no data on the use of these chromophores in RET systems, with the exception of a few ref.…”
