Boron-dipyrromethene based specific chemodosimeter for fluoride ion

3,5-Bis(trimethylsilylethynyl)-4,4-difluoro-8-(4-tolyl)-4-bora-3a,4a-diaza-s-indacene [BODIPY(CCTMS)(2)] has been synthesized by coupling of 3,5-dibromo-4,4-difluoro-8-(4-tolyl)-4-bora-3a,4a-diaza-s-indacene with trimethylsilylacetylene under pd(0) coupling conditions. The BODIPY(CCTMS)(2) was used as a selective colourimetric and fluoorescent chemodosimeter for fluoride ion, following the F- ion induced cleavage of trimethylsilyl group, the protecting group of ethyne functionality by monitoring the changes ill UV-vis and fluorescence properties The dosimeter BODIPY(CCTMS)(2) display clear changes ill colour, absorption and emission hands selectively for F- ion over other anions such as Cl-, Br-, I-, ClO4- and HPO42- (C) 2010 Elsevier Ltd All rights reserved
