Abstract

In order to reveal the effect of the donor units on the structure-property relationship, three novel directly linked donor-acceptor type systems, 1-3, which are based on thiophene and pyridine conjugates, are designed, synthesized and characterized by spectroscopic methods. It is noteworthy that these D-A systems exhibit distinct electrochemical and optical features depending on the strength of the D-unit or the conjugation length. Furthermore, it is found that two of these novel systems, 2 and 3, can be used in both chromogenic and fluorogenic detection of Cu2+ among other ions. (C) 2013 Elsevier Ltd. All rights reserved.
