  名称：

  A simple quinoxaline-based highly sensitive colorimetric and ratiometric sensor, selective for nickel and effective in very high dilution

  摘要：

  A new quinoxaline based receptor (HQNM) has been designed and synthesized which shows a remarkable color change from colorless to yellow on specific binding with nickel. The cation recognition property of the receptor is monitored by the UV-vis and H-1 NMR titrations. It is observed that the receptor shows a specific selectivity toward nickel over other interfering cations. Thus, a significant bathochromic shift in UV-vis spectrum with a sharp yellow color in 'naked-eye' makes the receptor suitable for the easy detection of nickel ion. (C) 2013 Elsevier Ltd.
