摘要：

A new fluorogenic ionophore has been prepared by conjugating calix[4]-crown-5 ether with boron-dipyrromethene fluorophore. The ionophore exhibited a pronounced selective ON-OFF type response toward Ca2+ ions over other physiologically important metal ions of Na+, K+, and Mg2+. The interaction with Ca2+ ions resulted in very efficient quenching of fluorescence at 507 nm excited by relatively long wavelength irradiation at 480 rim. The selectivity ratios toward Ca2+ ions over other tested physiologically important metal ions were larger than 180 in aqueous 95% MeOH solution. (C) 2003 Elsevier Ltd. All rights reserved.
