Porphyrins Sheathed in Quadrupolar Solvation Spheres of Hexafluorobenzene: Solvation-Induced Fluorescence Enhancement and Conformational Confinement

摘要

Hexafluorobenzene (C6F6) strongly solvated the porphyrin ring via a quadrupolar interaction. The solvation sphere of C6F6 hindered the thermal fluctuations near the porphyrin ring and evoked remarkable photoelectronic properties of the porphyrins such as fluorescence enhancement and spectral sharpening due to confined torsional planarity.
