Suarez, Mauricio 2011-05-07T13:51:15Z 2011-05-07T13:51:15Z 10000-01-01 1995 The tendency for miniaturization in electronic devices has created the need for materials capable of high storage densities and high switching rates. There has been ample effort in bringing this miniaturization to the molecular level, i.e. the design of molecular switches. The possibility of using photons to address a switch at an specific site in a volume has motivated research in photoresponsive compounds. An interesting family of photoresponsive compounds are those that are sensitive to the sense of chirality of light. Compounds capable of photoresolution can be switched between a scalemic and a racemic state, this can be the basis for a chiroptical switch. Important parameters to control in the design of a photoresolvable compound are the optical properties that determine the degree of enantiomeric excess that one can attain at the photostationary state, the g value. Two strategies to increase the g value were investigated: exciton coupling and energy transfer. Energy transfer was shown to be an efficient strategy in the design of photoresolvable compounds. Specifically, a compound capable of generating a reversible enantiomeric excess of 0.4% has been design using this strategy. The implications of photoresolvable compounds in the creation of a chiroptical liquid crystalline switch are discussed. Made available in DSpace on 2011-05-07T13:51:15Z (GMT).
