通过整合蒽、1,3-二硫醇-2-硫酮和联萘单元的特征，研究了(S)-1及其类似物(S)-2（包含两个1,3-二硫醇-2-1单元而不是1,3-二硫醇-2-硫酮），以创建新的分子调控系统并构建门控手性分子开关。结果表明，光二聚化是通过C=S到C=O的远程官能团转变来控制的，从而提供了分子调控的一个很好的例子。两个蒽单元的光二聚作用引起圆二色性（CD）光谱变化。总体而言，CD光谱可以通过(S)-1中的Hg2+远程调制，从而产生Hg2+门控的手性分子开关。
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 of C=S into C=O, thus providing an elegant example of molecular regulation. The photodimerization of two anthracene units induces circular dichroism (CD) spectral variation. Overall, the CD spectrum can be remotely modulated by Hg2+ in (S)-1, which leads to an Hg2+-gated chiral molecular switch.
