Abstract
N-(9-Anthryl) aza-18-crown-6 (3) was synthesised via the palladium-cat alysed cross-coupling of 9-bromoanthracene (1) and aza-18-crown-6 (2). Its photophysical properties include an intramolecular charge-transfe r absorption band (lambda(max)approximate to 425 nm) in polar and nonp olar solvents, which disappears upon protonation or binding of K+ (log K-ass = 3.7 in acetonitrile).
