摘要:
A new and an easy-to-make simple tripodal shaped chemosensor 1 has been designed and synthesised for metal ions. In CH3CN containing 0.04% DMSO, upon excitation at 370nm, chemosensor 1 exhibited structured emission centred at 418nm, which increased to a significant extent upon complexation of Cu (II). The other metal ions except Zn2+ and Hg2+ examined in this study did not exhibit any marked change in emission of 1 under a similar condition. Although Cu2+ ion showed strong interaction with 1, Zn2+ and Hg2+ ions exhibited moderate binding.
