Tetraphenylmethane (1) and several functionalized tetraphenylmethanes 4-7, all of them useful building blocks for the construction of tetraarylmethane frameworks, are readily synthesized by improved standard procedures in multigram quantities. The structure of compound 5 has been additionally corroborated by an X-ray structure analysis. The novel class of tetrakis(thiazolylphenyl)methanes 8 showing a significant blue emission upon UV-excitation can be prepared in good yield by Hantzsch synthesis starting from the tetra(α-bromoketone) derivative 4b.

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.
