C3 symmetric ferrocenyl triazines: synthesis, structure, and properties

A series of C-3 symmetric ferrocenyl-substituted 1,3,5-triazines has been designed and synthesized by the Sonogashira cross-coupling reaction. The photophysical and electrochemical properties of these triazines show substantial donor-acceptor interaction. The single crystal X-ray structure of triazine 3 is reported, which shows a planar structure. The supramolecular structure of 3 exhibits intermolecular pi-pi interaction, which leads to the formation of 2D layered structures.
