Abstract

A hexakis(pyrenyloxy) cyclotriphosphazene is synthesized by the reaction of N3P3Cl6 with 2-hydroxypyrene, and its excimer emission through intramolecular interactions in solution and in the solid state has been investigated by fluorescence spectroscopy and X-ray crystallography. Thermal and electrochemical properties were investigated. A DFT benchmark study has been performed to evaluate the intramolecular interactions and molecular orbital levels by comparing with the experimental results.
