Title	Synthesis and Photophysical Properties of Bispsoralen Derivatives Linked by a Bisamide-polymethylene Chain
Author	Dong Jin Yoo
Keywords	8-Methoxypsoralen, Bispsoralen derivatives, UV absorption, Fluorescence emission spectra, Ring-ring stacking interaction
Abstract	New bispsoralen derivatives 5-10, 8-MOP-NHCO(CH₂)_nCONH-8-MOP (BPSBA-Cn, n = 0, 1, 2, 3, 4 and 5) in which 5 position of an 8-methoxypsoralen (8-MOP) is linked by various lengths of bisamide polymethylene chain to 5 position of the other 8-MOP, have been synthesized by the amidation of 5-amino-8-methoxypsoralen (12) with α,ω-alkanoyl dichloride. Photophysical properties of their derivatives including π?π stacking interaction between the two aromatic moieties were investigated by UV absorption and fluorescence emission spectra. Efficient ring-ring stacking interactions have been observed in BPSBA-C4 (9) from the percent hypochromism (%H) of the models.
