| Abstract;As one of our ongoing projects to develop novel molecular systems possessing "dynamic" functions coupled with chirality, we have investigated use of a large-sized dibenzo-30-crown-10 congener as a suitable scaffold toward this end. Currently an X-ray crystallographic study for Kl complex of the derivative with bis(arylthiourea) units (1) has revealed that a novel achiral-to-chiral transformation of the diaza-crown ether unit arises via an ion-pair coordinated self-assembly in the solid state. Based on the insight, we have successfully synthesized bis(Zn(II)porphyrin)-derived system (2) to estimate chirality induction phenomena through host-guest interactions with chiral diamines. The intrigued results will be reported in the presentation. (author abst.) |
