通过柱层析结合使用手性辅助亚砜配体的非对映体络合物的结晶来制备对映体纯的单环铂化-[8]螺烯和双环铂化-[6]螺烯衍生物。这些新的螺旋复合物的紫外-可见光谱，圆二色性，摩尔旋转，和（圆偏振）发光活性进行了详细研究和分析的帮助下，第一性原理量子化学计算。
Enantiopure mono-cycloplatinated-[8]helicene and bis-cycloplatinated-[6]helicene derivatives were prepared through column chromatography combined with crystallization of diastereomeric complexes using a chiral ancillary sulfoxide ligand. The UV-visible spectra, circular dichroism, molar rotations, and (circularly polarized) luminescence activity of these new helical complexes have been examined in detail and analysed with the help of first-principles quantum-chemical calculations.
