Shall we twist? Three‐dimensional arrangement of π‐conjugated chromophores with triple‐stranded helicity was achieved by using the planar chirality of m‐calix[3]amide (see figure). Based on spectroscopic data and theoretical calculations, the dynamic and preferred helical characters of bithiophene units embedded in the tubular molecule were elucidated, and the absolute configuration was determined
我们可以扭转吗?通过使用m- calix [3]酰胺的平面手性,实现了具有三链螺旋的π共轭生色团的三维排列。根据光谱数据和理论计算,阐明了嵌入管状分子中的联噻吩单元的动态和优选螺旋特征,并确定了其绝对构型。
