Abstract: | The new host compounds 2 and 3 containing a biphenyl or terphenyl moiety attached to the 1-position of a bulky 2,3,4,5-tetraphenylcyclopentadiene-1-ol building unit have been synthesized. Crystal structures of corresponding inclusion complexes with n-hexane (2a), DMSO (2b) and THF (3a) are reported and comparatively discussed involving known inclusion structures of 1, being the parent of this particular class of host molecules. The structural modification from 1 via 2?C3 gives rise to distinct changes of the inclusion property concerning molecular assembly and stoichiometric ratio of the crystal components. |
