摘要
The structure of the host compound 1,4-bis(9-hydroxy-9-fluorenyl)benzene as well as the structures of the inclusion complexes with four amides, dimethylformamide (DMF), dimethylacetamide (DMA), tetramethylurea (TMU) and hexamethylphosphoramide (HMPA) have been elucidated. Each structure crystallised in a centrosymmetric space group with Z = 2 and a host to guest ratio of 1:1 or 1:2, as determined by thermogravimetric analysis. Lattice energies have been calculated by atom-atom potential methods and these results were compared to the thermal stabilities observed.
