Selective Solvent-Free Friedländer Synthesis and Supramolecular Chemistry of 13,14-Diphenyl-6,7-dihydrodibenzo[b,j][4,7]phenanthroline

Solvent-free Friedländer condensation of 1,4-cyclohexadione with 2-aminobenzophenoneled to the formation of 13,14-diphenyl-6,7-dihydrodibenzo[b,j][4,7]phenanthroline as singleproduct. The crystal structure of 13,14-diphenyl-6,7-dihydrodibenzo[b,j][4,7]phenanthroline isdetermined using X-ray single crystal technique which reveals that it crystallises by the formation of network lattices that involve only weak assembly interactions.
