Abstract
Circularly polarized luminescence (CPL) has emerged as an intrigung photophysical phenomenon with potential applications in optoelectronics, bioimaging, and anti-counterfeiting materials. Among various CPL-active molecules, chiral boron difluoride complexes have attracted considerable attention due to their structural versatility, tunable emission properties and high luminescence efficiencies. This review summarizes recent progress in the design, synthesis, and photophysical properties of chiral boron difluoride complexes exhibiting CPL. We highlight key structural motifs, including boron-dipyrromethenes (BODIPYs), boron β-diketonates and boranils that have been successfully employed to induce efficient CPL activity. Moreover, we discuss the relationships between molecular structure and CPL performance, the mechanisms underlying CPL generation, and emerging strategies to improve emission efficiency and chiroptical properties. Finally, future perspectives are outlined with an emphasis on the challenges and opportunities in developing next-generation CPL-active materials based on boron difluoride frameworks.
期刊介绍:
Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions.
The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
