Our studies of helicenes are summarized in regard to chiral recognition phenomenon in noncovalent bonding interactions. The interactions between helical molecules show a tendency for pairs of the same configuration of the helicenes to form more stable complexes than pairs of enantiomeric helicenes. The observations are made in charge transfer complexation, crystallization, homocoupling reaction, layer structure formation, self-aggregation, and double helix formation. The interactions between a helicene and a right-handed helical polymer, double strand DNA, are also described.
我们关于螺旋烯的研究，是围绕非共价键相互作用中的手性识别现象进行总结的。螺旋分子之间的相互作用显示出一种倾向，即具有相同构型的螺旋烯对形成的配合物，要比旋光对映体螺旋烯对形成的配合物更稳定。这些观察结果是在电荷转移络合、结晶、均偶联反应、层状结构形成、自聚集以及双螺旋形成等过程中得出的。文中还描述了螺旋烯与右手螺旋聚合物、双链DNA之间的相互作用。
