Abstract
Solid polymeric materials for detection, transfer, amplification and memory of chirality of optically active compounds are described. These materials not only are able to absorb also traces of volatile organic compounds (both chiral and achiral) prevailingly as guest of a nanoporous crystalline phase, but for the case of chiral guests are also able to transfer and amplify their chirality, producing intense phenomena of induced circular dichroism (ICD). This induced dichroism remains stable also after chiral guest removal, as well as after temperature increases at least up to 250° C. The solid polymeric materials of the present invention can find applications in sensorics of optically active molecules as well as in systems for storage of data.
