Abstract

A new emissive molecular probe derived from 1,7-bis(2′-formylphenyl)-1,4,7-trioxaheptane and 2-hydroxy-1-naphthaldehyde has been synthesized by a Schiff-base condensation method. Its sensor capability towards cations such as Cu²⁺, Zn²⁺, Cd²⁺ and Hg²⁺, and anions such as halides (F^-, Cl^-, Br^- and I^-) and CN^- was explored in DMSO solution. The geometry was optimized using density functional theory (DFT). The probe showed remarkable selectivity for Cu²⁺ and interaction with the more basic anions CN^- and F^-.
