Molecular recognition of a large bisphenol A derivative, α,α′-bis(4-hydroxyphenyl)-1,4-diisopropylbenzene, using p-benzoquinone derivatives

Abstract

Using p-benzoquinone and its derivatives as electron acceptors, charge-transfer (CT) complexes with a large bisphenol A derivative, i.e., α,α′-bis(4-hydroxyphenyl)-1,4-diisopropylbenzene, were successfully formed. The complexation behavior and color of the CT complexes varied with the crystallization method and p-benzoquinone derivative. This CT system may be applicable for sensitive and visible recovery and indication of large bisphenol A derivatives.
