Abstract
The synthesis and characterization of some bis-7-oxabenzo-alpha-pyrone ended polyoxyethylenes is reported and their electronic spectra evalu ated. Their fluorescence spectra showed cation specific spectral inten sity changes in the presence of Na+, K+ and Pb2+ in acetonitrile due t o the cation complexing. Copyright (C) 1996 Elsevier Science Ltd
