Abstract
Abstract 4′-(4-{2-[6,7-Bis-dodecyloxy-3-(2- p -substituted phenyl-vinyl)-quinoxalin-2-yl]-vinyl}-phenyl)-[2,2′:6′,2″] terpyridine was prepared by the Horner–Wadsworth–Emmons (HWE) reaction of 4-[2,2′:6′,2″]terpyridin-4′-yl-benzaldehyde and quinoxaline derivatives. The absorption and fluorescence maximum of these compounds were observed at 398–443 nm and 484–586 nm, respectively. The compounds were characterized by 1 H NMR spectroscopy and MALDI-TOF-MS, and their recognition properties for metal ions were evaluated using both absorption and emission spectroscopy.
