合成了第一个具有较大环基构象柔性的合理化冠醚-双卟啉共轭物1;与手性二胺络合后，在冠醚部分容纳的K（+）的帮助下，非手性转化为手性，并且可以确定羧酸钾盐的手性。
The first rationalized crown ether-bis(porphyrin) conjugate with a large ring-based conformation flexibility 1 has been synthesized; the achiral-to-chiral transformation upon complexation with chiral diamines is assisted by K(+) accommodated in the crowned moiety, and it is possible to determine the chirality of carboxylates as potassium salts.
