Ferrocene-Based Triazine Compounds: Synthesis, Properties, and Applications

Abstract

Both ferrocene derivatives and triazines exhibit significant photoresponsive behavior and can serve as effective photoinitiators or photodegradation catalysts for polymeric materials. Three ferrocene-functionalized triazine derivatives were synthesized via sequential ferrocenylzinc addition and resorcinol nucleophilic aromatic substitution. The compounds were characterized by UV-Vis and TGA. TGA showed good thermal stability for these three compounds. Theoretical calculations further elucidated their molecular orbitals, energy levels, and excited-state transitions. To assess their photodegradation performance, composite PVC films incorporating the three compounds were prepared and subsequently subjected to accelerated aging under UV light. The degradation process within the PVC matrix was monitored and characterized primarily by Fourier transform infrared (FTIR) spectroscopy and Gel permeation chromatography (GPC). Precise control of the photodegradation rate was achieved by modulating the number of ferrocene units and the substituents on the 1,3,5-triazine ring.
