Synthesis and Electronic Properties of Tetrakis[4-(pyrimidyl)phenyl]methanes − A Novel Class of Electronically Active Nanometer-Sized Scaffolds

Tetrakis[4-(arylpyrimidyl)phenyl]methanes 4 can be readily synthesized by using a highly convergent vinamidinium salt cyclocondensation strategy. The conjugated side-chains of these novel nanostructures display interesting cooperative electronic features such as intramolecular exciplex coupling and ECEC redox processes in the cathodic region.
