Abstract
2,2′-3,3″-Terthiophene derivatives undergo photochemically reversible cyclization and cycloreversion reactions. The absorption peak wavelength changed systematically with substitution of the phenyl rings at 5-, 5′- and 5″-positions of the thiophene rings, which indicates re-routing of the π-conjugation system.Keywords
