Two novel enantiomerically pure chiral ligands and the corresponding neutral Pt complexes have been synthetized and characterized. The self-assembly properties of the complexes have been investigated using different morphological and photophysical techniques. The two enantiomeric complexes, 4 a and 4 b, show high tendency to self-assemble into chiral supramolecular aggregates with right (P) and left-handed (M) helical configurations, respectively, as proven by SEM and absorption circular dichroism. The formation of such organized structures is driven by the formation of metallophilic and π-π interactions between spatially close Pt complexes with an enhancement of the chiro-optical properties in the solid state.
两种新型对映体纯的手性配体以及相应的中性铂配合物已被合成并表征。使用不同的形态学和光物理技术研究了配合物的自组装性质。两种对映体配合物4 a和4 b分别表现出高自组装倾向，形成具有右手（P）和左手（M）螺旋构型的手性超分子聚集体，扫描电子显微镜（SEM）和吸收圆二色性已证实这一点。这种有序结构的形成是由空间上接近的铂配合物之间形成亲金属相互作用和π-π相互作用驱动的，同时增强了固态下的手性光学性质。
