Triarylmethanol Host Compounds. Synthesis, Crystalline Complex Formation and X-Ray Crystal Structures of Three Inclusion Species (Journal article)

E. Weber,/ K. Skobridis,/ A. Wierig/ I. Goldberg

A variety of triarylmethanol compounds including benzo condensed and laterally substituted derivatives 1-10 have been prepared and shown to act as crystallinehosts for the inclusion of organic solvents involving protic polar, aprotic dipolar and apolar molecules. The inclusion ability is ratherhigh for aprotic dipolar solvents while protic polarcompounds are only rarely enclathrated. Host 9 is an exception, being also efficient with alcohols and amines. Compound3 displays no inclusion formation under theexperimental conditions. X-ray crystal structures of the inclusion compound 1β‹…acetone (2:1) and of two amineinclusion compounds of host 9 [9β‹… n-propylamine(1:1), 9β‹…di-n-propylamine (1:1)] are reported showing the formation of H-bondedhost-guest associates as the common feature of supramolecular association.
