New building block for C(3) symmetry molecules: synthesis of s-triazine-based redox active chromophores.

A new s-triazine-based C(3) building block, endowed with three phosphonate groups, has been prepared in a simple two-step synthesis starting from p-bromomethylbenzonitrile; the new building block easily undergoes further olefination reactions to afford in a straightforward manner tris(tetrathiafulvalene)- and tris(ferrocene)-1,3,5-triazines.
