Halogen bonding has emerged as a powerful tool for self-assembly due to its highly directional and hydrophobic nature. In spite of the number of one dimensional or infinite linear networks assembled by 1,4-DITFB with different acceptors, no example describing C–I π halogen bonding phosphorescence crystal has been reported. In this hot article Wei Jun Jin and colleagues at Beijing Normal University, China, describe a new organic phosphorescent co-crystal material based on 1,4-DITFB and carbazole. The team says that The halogen bonding of 1,4-DITFB with carbazole is selective, and the co-crystal microparticle suspension displays strong phosphorescence. Wei Jun Jin and the team say this is the first report of a phosphorescent co-crystal assembled by weak C–I π interaction. Read the article for free until 30th April.
