Abstract
AbstractNovel derivatives of 4,4‐difluoro‐1,3,5,7,8‐pentamethyl‐4‐bora‐3a,4a‐diaza‐s‐indacene (BODIPY) functionalized at the meso‐position with polyamines and polyoxyethylenes were synthesized through single‐step condensation of fluorogenic 8‐CH2Cl‐substituted BODIPY and corresponding amines. The systematic spectroscopic characterization (UV‐Vis, fluorescence) of stable in storage dyes bearing polyoxyethylene substituents was carried out. One compound showed promise for UV‐Vis and “off‐on” fluorescence Cu2+ detection in acetonitrile solutions. The ligand detects Cu2+ ions selectively in the presence of eighteen different alkaline earth metal cations.
