The influence of the linker on electrochemical and spectroelectrochemical properties of donor-acceptor-donor triphenylamine-s-tetrazine derivatives

Pluczyk, S; Zassowski, P; Quinton, C; Audebert, P; Alain-Rizzo, V; Lapkowski, M, Electrochimica Acta, 2016, 216, 160-170.

We report on electrochemical and spectroelectrochemical (UV-Vis, EPR) investigations of donor-acceptor-donor triphenylamine-s-tetrazine derivatives with different linkers between donor and acceptor part of molecules. The influence of the chemical nature of the linker on properties of studied compounds was observed and analyzed. Tuning of the conjugation level between donor and acceptor part of molecules results in different activity in the electrochemical polymerization (oligomerization) process. The investigations of the polymerized layers have revealed interesting features. Thin polymeric films exhibit charge trapping phenomena, together with a storage properties. In order to conduct more precise analysis, the DFT/TDDFT calculations were carried out which provided comprehensive characteristics of investigated molecules.
