Perylene diimide (PDI) derivatives with cyclodextrins (PDI-CD2s) exhibit specific emission properties, which depend on the type of CDs in an aqueous solution. Herein we create an emission from film kneaded PDI-CD2s derivatives via effective tumbling of the altropyranose unit. We have observed the selective emission of PDIC7-3βCD2 in aqueous solutions and prepared emission films kneaded into polyvinyl alcohol (PVA) films. The emission depends on the cavity size of the altro-CDs formed through altro-CD tumbling.
