Guest-dependent Structural Transformation of Dehydrobenzoannulene Inclusion Crystals Composed of pi-Stacked Parallelogram Columnar Motifs
Octadehydrotribenzo[14]annulene (DBA) derivative 1 gave inclusion crystals with thirteen kinds of aromatic guest molecules. Heat-induced guest release of the inclusion crystals resulted in the formation of guest-free polymorphs, Forms I and III, which depended on the guest species.
