Abstract
New unsymmetrically substituted 5,5?-diaryl-2,2?-bypiridine “push-pull “ fluorophores were prepared in good yields via the “1,2,4-triazine method “/Suzuki coupling reaction sequence. The obtained fluorophores contain the “push-pull “ system with donor and acceptor moieties arranged in a D-?-A-?-D fashion, and that provides both the prospective photophysical properties and unique solvatocromic effects for the most representative compounds.
