Abstract
Synthesis of the diastomers of 1,4-bis(p-methoxyphenyl)-2,3-dyphenylbutan-1,4-dione (compound 1) revealed that the diastereomeric discrimination in the lifetimes for compound 1-meso and compound 1-rac is a direct result of conformational control. The efficiency of this discrimination in solution makes compound 1 a potential probe for studying the chirality of supramolecular structures. Photochemical probes with a stereocenter that affects their photophysics are desirable to the study of the dynamics and local mobility of supramolecular structures.
