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 Hg²⁺ in THF/H₂O (99:1, v/v) in the presence of various other metal ions. Such selectivity is not seen with half salen 1 derived from salicylaldehyde and 1-aminopyrene. ¹H NMR analysis reveals that it is a chemodosimetric sensor based on its hydrolysis mediated by Hg²⁺ to release 1-aminopyrene molecules as fluorescent chromophores.
