Two terphenyl-based diol hosts and corresponding solvent inclusions with dimethylformamide and acetonitrile.

Having reference to an elongated structural modification of 2,2'-bis(hydroxydiphenylmethyl)biphenyl, (I), the two 1,1':4',1''-terphenyl-based diol hosts 2,2''-bis(hydroxydiphenylmethyl)-1,1':4',1''-terphenyl, C44H34O2, (II), and 2,2''-bis[hydroxybis(4-methylphenyl)methyl]-1,1':4',1''-terphenyl, C48H42O2, (III), have been synthesized and studied with regard to their crystal structures involving different inclusions, i.e. (II) with dimethylformamide (DMF), C44H34O2·C2H6NO, denoted (IIa), (III) with DMF, C48H42O2·C2H6NO, denoted (IIIa), and (III) with acetonitrile, C48H42O2·CH3CN, denoted (IIIb).
