摘　　要：The calix[4]arene-based podands which incorporates two terpyridinyl functional groups derived from the alkylatiorl reactions of 4-（co-chloroalkoxyphenyl）-2,2＇：6＇,2＂-terpyridine in 1,3-alternate position at lower rim have been prepared in moderate yields. The structures of four pyridyl compounds were determined by X-ray single crystal diffraction method. The complexing properties of bis-terpyridinyl-calix[4]arenes for transition metal ions were inves- tigated by fluorescence spectra. Bis-terpyridinyl-calix[4]arenes gave a more efficient fluorescent sensing ability to Zn2＋.The calix[4]arene-based podands which incorporates two terpyridinyl functional groups derived from the alkylatiorl reactions of 4-（co-chloroalkoxyphenyl）-2,2＇：6＇,2＂-terpyridine in 1,3-alternate position at lower rim have been prepared in moderate yields.
