Synthesis of peri-Diarylated Naphthalimides via Double Decarboxylative Cross-Coupling Reaction

Abstract

A facile method for the synthesis of peri-diarylated naphthalimides was developed by using a palladium-catalyzed double decarboxylative cross-coupling reaction. The present work offers a convenient approach for tuning the optical properties of naphthalimide derivatives.

“…10 Among these, functionalized PADIs, especially naphthalene and perylenemonoimides, are the most investigated PADIs as these peri -functionalized PADIs with electron donating groups can create donor-π-acceptor or push–pull systems. 11 Introduction of the push–pull systems provides desirable low band gaps because of the ground state destabilization of the donors and excited state stabilization of the acceptors. 12 In addition, large Stokes shifts and high fluorescence quantum yields have been reported for the push–pull PADIs.…”
