The phosphorescent co-crystals of 1,4-diiodotetrafluorobenzene and bent 3-ring-N-heterocyclic hydrocarbons by C–I⋯N and C–I⋯π halogen bonds

Abstract

Co-crystals assembled from 1,4-diiodotetrafluorobenzene and bent 3-ring-N-heterocyclic hydrocarbons <italic>via</italic> C–I⋯N and C–I⋯π halogen bonds emit green, orange-yellow and orange phosphorescence.
