The redox behavior of the ene-diyne compounds was examined by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Moreover, a significant color change of the ene-diyne derivatives was observed with visible spectroscopy under electrochemical reduction conditions., Article, EUROPEAN JOURNAL OF ORGANIC CHEMISTRY. 2013(5):957-964 (2013)}, pages = {957--964}, title = {Synthesis, Properties and Redox Behavior of Ene-Diyne Scaffolds Bearing 1- and 2-Azulenyl Groups at the Periphery}, volume = {2013}, year = {2013} }
