- Abstract
- 4'-(4-{2-[6,7-Bis-dodecyloxy-3-(2-substituted-phenyl-vinyl)-quinoxalin-2-yl]-vinyl}-phenyl)-[2,2':6',2 ''] terpyridine was prepared by the Horner-Wadsworth-Emmons reaction of 4-[2,2':6',2 '']terpyridin-4'-yl-benzaldehyde with various quinoxaline derivatives. The absorption and fluorescence maxima of the compounds were observed at 398-443 nm and 484-586 nm, respectively; the compounds offer potential as optical sensors for protons and metal ions.
