Synthesis of novel calix[4]crown telomers and selective extraction of cesium ions
《Chinese Chemical Letters》2007年第3期263-265,共3页Hai Bing Li Yuan Yin Chen De Jun Xiong Jun Yan Zhan Cui Ping Han 
Financial supports from the National Natural Science Foundation of China(No.20602015)are gratefully acknowledged.
p-tert-Butylcalix[4]diazacrown-4 telomer, which contains hard and soft ion binding sites, was synthesized. It exhibited high selectivity toward cesium ions. The binding sites may complex alkali metal ions selectively.
