Complexation with diol host compounds. Part 17. Structures and thermal analysis of 9,9′-dihydroxy-9,9′-bifluorene with ethanol, 1-butanol and pyridine

Abstract Structures of the inclusion compound 9,9′-dihydroxy-9,9′-bifluorene with ethanol, 1-butanol and pyridine have been determined. The structures are stabilised by networks of hydrogen bonds. The thermal analysis indicates a single step decomposition process with concomitant phase transition of the structures. Accurate vapour pressure measurements at various temperatures yield the enthalpy change for the guest release reaction.
