Hexakis{4-[(4′-hydroxybiphenyl-4-yl)ethynyl]phenyl}benzene

Sterically congested quinone methides in photodehydration reactions of 4-hydroxybiphenyl derivatives and investigation of their antiproliferative activity.

In aqueous media, photochemical excitation (S(1)) of hydroxyadamantyl, diphenylhydroxymethyl, and hydroxypropyl derivatives of 4-phenylphenol 5-9 leads to solvent-assisted deprotonation of the phenol OH, and protonation of the benzyl alcohol coupled with dehydration, that delivers quinone methides (QMs) 14-18. The QMs react with CH(3)OH converting them in high quantum yields to the photosolvoly...
