Abstract
Calix[4]crown-based chemosensors 1, 2, and reference 3 have been synthesized. The weak fluorescence intensity of 1,5-naphthalene of 1 suggests that the benzene rings of the calix[4]arene as well as the oxygen atoms of the crown-5 ring take part in PET. The complexation of two K+ ions by both crown-5 and 1,5-naphthalene-crown-6 loops of 1 caused fluorescence enhancement of the naphthalene unit by CHEF. Pb2+ acted as a quenching metal ion.
