PN-Containing Pyrene Derivatives: Synthesis, Structure, and Photophysical Properties

摘要

A straightforward method for the preparation of non-K region fused phosphorus- and nitrogen-containing (PN)-heterocyclic pyrenes has been accomplished. Their structural, photophysical, and electrochemical properties have been fully investigated. The described compounds exhibit intriguing redox properties and show strong photoluminescence with a wide range of tunable emission colors, with lambda(em) ranging from blue at 459 nm to red at 622 nm in CH2Cl2 solution.
