Popis:	The solid host compound 2,2'-bis (9-hydroxy-9-fluorenyl)biphenyl 1 enclathrates organic solvent vapours such as acetone, methanol and 1-butanol to give stoichiometric inclusion complexes. Using differential scanning calorimetry (DSC), desorption enthalpies were estimated to 10-20 k J/tool, indicating weak host-guest interactions. Clathrate formations with acetone and methanol are reversible and reproducible, and show a dependence of the mass increase on the solvent concentration in a gas flow. The application of host compound 1 as receptor layer can be important for the future developmen of mass sensors for the determination of organic solvent vapours. Fresen. J. Anal. Chem.
