%A Michael Thomas Martucci %T DEVELOPMENT OF PHOTO-SENSITIZED PRECIPITONS AND STUDIES TOWARD THEIR USE AS LIGHT-ACTIVACTED, REVERSIBLE PHASE TAGS %X This dissertation chronicles the discovery and development of an intermolecular photosensitized trans to cis isomerization protocol for bi-phenyl phenyl precipiton phase tags. The optimization of reaction and irradiation conditions, scale-up experiments and isomerization kinetics are presented. This class of precipiton can now be used as a dynamic reversible phase tag ideally suited for multi-step synthesis on multi-gram scale %D 2009 %K organic synthesis; photosensitizer; precipiton; phase tag; separation %I University of Pittsburgh %L pittir8881
