摘要：

Systematic studies towards the formation of thia-anthracene receptors were performed. Anthracene podand 3 consisting of two anthryl groups connected by the SCH2CH2CH2S spacer group was prepared in 99% yield. The complexation properties of this compound were investigated using UV-VIS and fluorescence titration techniques. Addition of silver salts into a solution of the fluorophore strongly modifies the absorption and fluorescence spectra and the association constants were found to be K-1 = 2 x 10(5) and K-2 = 8 x 10(4) M-1 for the 1:1 and 1:2 complexes, respectively. Addition of metal ions, as Cu2+, Zn2+, Cd2+, Hg2+, Ni2+, and Co2+, did not lead to any change in the photophysical properties of compound 3. (C) 1999 Published by Elsevier Science Ltd.
