High Pressure Study on Intramolecular Excited Complex and Role of Ground-State Conformation

Abstract

The effects of high pressure on the luminescence properties of bichromorphic compounds, i. e., (9-anthryl)-(CHI),-(9-anthryl) systems and p-(CH, )>NC, H,-CH,-(9-anthryl), were investigated. They were studied in a polymeric environment in order to eliminate intermolecular interactions. Two types of intramolecular interactions, I . e., " through-bond interaction" and " through-space interaction." are distinguished by the different presswe effects, depending on the ground-state molecular conformations.
