Abstract

A novel class of molecular clips based on diethoxycarbonyl glycoluril was synthesized via click chemistry. Seven different arylacetylenes were used in this research, and all reaction products gave satisfying ¹H NMR, ¹³C NMR, HRMS, and IR spectra. The structure and conformation of 7a were further confirmed by single-crystal X-ray diffraction. A primary study on the metal-ion binding ability of 7f showed that its fluorescence was obviously quenched by Fe³+, Ag+, and Cu²+ among metal ions examined.
