Desolvation mechanism of crystalline host-guest compounds considering pseudopolymorphism: Study of the 1,1 '-binaphthyl-2,2 '-dicarboxylic acid clathrates with DMF

Communication: Inclusion compounds have significant potential as chemical r eceptors for sensors; however, it is necessary to understand the encapsulat ion and release processes for such applications. These authors have utilize d the powerful combination of simultaneous thermogravimetry and differentia l scanning calorimetry and X-ray diffraction to study the decomposition mec hanism of the clathrates between 1,1'-binaphthyl-2,2'-dicarboxylic acid (BN DA) and dimethyl formamide (DMF). Decomposition was found to proceed via th ree intermediate phases whose structures were determined by single crystal X-ray crystallography.
