Exciton-chirality induction

Kikuchi, Y., Kobayashi, K., and Aoyama, Y. (1992) Complexation of chiral glycols, steroidal polyols, and sugars with a multibenzenoid, achiral host as studied by induced circular-dichroism spectroscopy exciton chirality induction in resorcinol-aldehyde cyclotetramer and its use as a supramolecular probe for the assignments of stereochemistry of chiral guests, J. Am. Chem. Soc. 114, in press. 

Although not within the scope of this chapter, it should be noted that excitonic coupling between B or Soret bands in achiral metalloporphyrin hosts or bis-metalloporphyrin tweezers are extensively used as an analytical tool for assignment of absolute configuration of chiral guests, by taking advantage of the induction of CD features in the achiral hosts".
