摘要：

A novel calix[4]arene based molecular probe for metal ions has been designed, synthesized and evaluated. Studies on its binding with different metal ions reveal a noticeable naked eye color change, bathochromic shift in absorption spectrum and remarkable enhancement in fluorescence emission in the presence of Cu2+ only. The role of calix[4]arene scaffold for selective recognition of Cu2+ has been demonstrated by repeat evaluation and analysis of an appropriate reference molecule. A rational explanation for fluorescence enhancement in (3) under bar on interaction with copper has been suggested. (C) 2014 Elsevier Ltd. All rights reserved.
