Azobenzene coupled chromogenic receptors for the selective detection of copper(II) and its application as a chemosensor kit

Lee, Soo Jin,Lee, Shim Sung,Jeong, Il Yun,Lee, Jin Yong,Jung, Jong Hwa

, p. 393 - 396 (2007)

Azobenzene-based receptors 1-4 as colorimetric sensing materials were synthesized and their sensing properties were examined. In solution, the proposed sensing materials give rise to a large cation-induced hypochromic shift for Cu2+ resulting i
