Abstract:Planar chiral organic fluorescent materials that exhibit high chiral stability, high efficiency and circularly polarized luminescence (CPL) concurrently remain an unresolved issue despite their promising applications in optical encryption and...
“…10) by introducing phenoxazine and triazine into [2.2]paracyclophane to produce intrinsic planar chirality. 51 The enantiomers displayed not only excellent TADF and CPL activities, but also a stable chiral configuration without racemization. These properties endowed the enantiomers with the ability to achieve highly efficient vacuum-deposited CP-OLEDs.…”

“…In recent years, circularly polarized luminescent (CPL) materials have attracted great attention and become a new research hotspot in the field of chiral luminescent materials. [1][2][3][4][5] Circularly polarized luminescence refers to the property that chiral luminescence systems can emit left-handed CPL and righthanded CPL with different intensities after excitation. Due to unique optical properties, CPL materials have a widespread application prospect in asymmetric syntheses, 6,7 chemical sensors, 8 chemical probes, 9 3D displays 10 and other fields.…”
In recently years, great progress has been made in the preparation methods and performance regulation of host-guest doped CPL liquid crystal materials. However, there still exist some basic problems to...
“…Introducing chiral units into classical D-A type TADF materials is an effective strategy to construct emitters for CP-OLED applications. [30][31][32][33][34][35][36][37][38][39][40][41][42] Nevertheless, the g lum values of D-A type CPL materials are generally low (in the range of 10 À3 to 10 À5 ). [43][44][45][46][47][48][49][50][51][52][53][54] Besides, the lack of understanding of the impact of structural variations on the g lum of D-A type CPL materials limits the rational improvement of g lum .…”
By employing aza[7]helicene as the chiral donor and triazine as the acceptor, we have developed a new type of circularly polarized luminescence materials. The influence of the dihedral angle between...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
