Four photoluminescent dye crystals, TPB-n (n = 1-3) and TPCH, have been synthesized in isolation from carbon-carbon coupling of 4,4'-trimethylene-dipyridine (tmdp) in the absence of organic solvent and catalyst via in situ one-pot metal/ligand oxidative-dehydrogenation reactions. Large crystals have been obtained and readily separated from reaction products without the need for purification. Their

1,3-Diiodotetrafluorobenzene and 1,3,5-trifluoro-2,4,6-triiodobenzene form co-crystals with 4,4â²,6,6â²-tetramethyl-2,2â²-bipyrimidine, 1,2,4,5-tetra(3-pyridyl)benzene and 1,2,4,5-tetra(4-pyridyl)benzene in which the structural competition between Ïâ¯Ï interactions and halogen bonds is directly observed. It is found that the strong CâIâ¯N halogen bond competes successfully with the Ïâ¯Ï interaction between two 1,3-diiodotetrafluorobenzene molecules while the Ïâ¯Ï interaction between two 1,3,5-trifluoro-2,4,6-triiodobenzene molecules can successfully compete with the strong CâIâ¯N halogen bond. Quantum chemical calculations explain the structural competition well.
