Synthesis and multicolor, photophysical, thermal, and conductivity properties of poly(imine)s

Abstract

Background: Thiazole-based conjugated have been attracted much attention due to their desirable photophysical properties. Based on this, we aimed to prepare thiazole-based poly(imine)s with tunable multicolor emission behavior in the present paper. Methods: Thiazole-based Schiff bases and poly(imine)s were prepared via condensation, and oxidation reactions, respectively. The tunable multicolor behavior of the poly(imine)s was also clarified using fluorescent measurements. Findings: The conductivity, thermal, photophysical, multicolor, morphological and electrochemical properties of the thiazole-based compounds were also clarified. Multicolor behavior of the poly(imine)s was demonstrated that they were emitted blue, green, and yellow emission colors when excited at 350, 420, and 480 nm, respectively. Thermal properties showed that the (poly(imine)s were exhibited good thermal stability. It was found that the thiazole-based poly(imine)s were exhibited a semiconductor behavior after iodine doped. The results indicated that the prepared poly(imine)s were exhibited tunable multicolor property with good thermal stability, and electrical conductivity.
