A binaphthalimide motif as a chiral scaffold for thermally activated delayed fluorescence with circularly polarized luminescence activity

Abstract

A new red-emitting CPL/TADF derivative is reported. A monomeric form is compared to its chiral dimeric counterpart to unravel the impact of dimerization on TADF properties. Circularly polarized fluorescence and phosphorescence are also investigated.

Achievement of efficient thermally activated delayed fluorescence materials based on 1,8-naphthalimide derivatives exhibiting piezochromic and thermochromic luminescence

“…[32][33][34] By nely tuning the molecular structure of these compounds, such as introducing different functional groups, their TADF characteristics can be effectively regulated to optimize their performance. [35][36][37][38] Previously, our research team synthesized red-emitting TADF materials based on 1,8-naphthalimide derivatives. 39 In this study, We altered the electron-donating component to carbazole and successfully synthesized NI-mPCz, which exhibited blue-green TADF properties.…”
