摘要：

A novel fluorescent sensor based on a pyrrole-derived pi-conjugated oligosquaraine containing diethylene glycol monomethyl ether side chain has been synthesized. This molecular wire based fluorescent sensor showed enhanced sensitiviy and specificity towards the recognition of Li+ when compared to Na+ and K+. An analogous simple squaraine dye could not sense any of the metal ions. (C) 1998 Elsevier Science Ltd. All rights reserved.
