Synthesis and Photophysical Properties of N-Arylcarbazolophanes

Abstract

We have so far prepared cyclophanes consisting of various aromatic rings such as phenanthrene and carbazole, and examined their electronic and photophysical properties, especially the excimer formation. Here, we have successfully synthesized triply-bridged N-arylcarbazolophanes via the intramolecular etherification of the precursors containing two N-aryl-3,6-bis(hydroxymethyl)carbazole moieties. Their electronic and photophysical properties were investigated in detail.
