Abstract

Six (pseudo)polymorphs (1α, 1β, 2α, 2β, 3, and 4) of an emissive quinoline derivative, TFMAQ-Ph-OMe, were demonstrated to undergo a two-step transformation caused by conformation- and packing-dominated processes, as indicated by changes of the corresponding emission properties and powder X-ray diffraction patterns. Upon grinding, all crystals produced polymorph 2α as the major product, which, in turn, underwent spontaneous transformation into polymorph 3 after being left for several hours.
