An Hg2+-Gated Chiral Molecular Switch Created by Using Binaphthalene Molecules with Two Anthracene Units and Two 1,3-Dithiole-2-thione (1,3-Dithiole-2-one) Units
By integrating the features of anthracene, 1,3-dithiole-2-thione, and binaphthalene units, (S)-1 and its analogue (S)-2, which contains two 1,3-dithiole-2-one units instead of 1,3-dithiole-2-thione, were studied for creating a new molecular regulation system and building a gated chiral molecular switch. The results show that the photodimerization is controlled by the remote functional-group transformation

A new binaphthalene (R)-1 with two substituted TTF and trichloroquinone units is reported. Both absorption and ESR spectral studies show that electron transfer occurs between TTF and trichloroquinone units of (R)-1 in the presence of metal ions (Pb2+, Sc3+, Zn2+, and Ca2+). We also propose a possible mechanism for this electron transfer process. But, the CD spectral change of (R)-1 in the presence of metal ions is rather small. (c) 2007 Elsevier Ltd. All rights reserved.
