Abstract

Abstract: A novel calixarene-based diimine, 1, 3-bis(pyren-1-yliminomethyl)calix[4]arene (5 ), serves as a turn-on-type fluorescent sensor, which selectively detects Hg 2+ in THF/H2 O (99:1, v/v) in the presence of various other metal ions. Such selectivity is not seen with half salen1 derived from salicylaldehyde and 1-aminopyrene. 1 H NMR analysis reveals that it is a chemodosimetric sensor based on its hydrolysis mediated by Hg 2+ to release 1-aminopyrene molecules as fluorescent chromophores.
