Inclusion compounds with mixed guests: controlled stoichiometries and kinetics of enclathration

The host compound trans-9,10-dihydroxy-9,10-bis(p-tert-butylphenyl)-9,10-dihydroanthracene forms inclusion compounds with DMF, DMSO and acetone of the type H.nG(1).(4 - n)G(2), with n varying integrally from 0 to 4. The structures of these compounds have been elucidated. The kinetics of enclathration with acetone vapour displays anti-Arrhenius behaviour and the desorption process has a low activation energy of 48.4 kJ mol(-1).
