Color-tuning and boosting circularly polarized luminescence performance of axially chiral tetra-BF₂complexes by post-modifications

Abstract

The design and synthesis of novel circularly polarized luminescence (CPL) molecular emitters exhibiting photophysical modulation and high CPL efficiency have become an attractive research topic in synthetic and material chemistry....

Solid-State Emissive meso-Aryl/Alkyl-Substituted and Heteroatom-Mixed BOPPY Dyes: Syntheses, Structures, Physicochemical, Redox Properties, and Computational Analysis

“…One notable application of the BOPPY fluorophore is in specifically lighting up subcellular organelles, showcasing its potential in biological imaging. A successful example of its application is seen in the development of flag-hinge BOPPY–dimer chromophores derived from diformyl-2,2′-bipyrroles by Ono and co-workers. − These chromophores display relatively strong circularly polarized luminescence with high asymmetry factors and fluorescence quantum yields. This highlights the versatility and potential of BOPPY fluorophores in various fields.…”

Unraveling the Remarkable Influence of Substituents on the Emission Variation and Circularly Polarized Luminescence of Dinuclear Aluminum Triple-Stranded Helicates

“…The introduction of substituents can induce significant changes in the molecular structure and packing mode of dyes, thereby establishing a correlation between structure–property relationships. Indeed, the introduction of substituents in dyes has been shown to alter properties such as optical functions, − magnetic properties, catalytic properties, photoswitching properties, , and chirality. − These changes not only open new possibilities in material science but also deepen our understanding of the relationship between structure–property relationships.…”

Simultaneous discovery of chiral and achiral dyes: elucidating the optical functions of helical and flag-hinged boron tetradentate complexes

“…This has led to variations in stereochemistry and conformation, opening up avenues for exploring new functionalities. [33][34][35][36] From the perspective of boron complexes, our group has focused on BOPAHY and BOPPY and reported the development of materials demonstrating white-light emission in the solid state, 15 near-infrared emission, 37 CPL, 9,38 electrochemiluminescence, 39 and amplified spontaneous emission 39 by dimerizing these chromophore frameworks through covalent bonding. These properties arise from variations in molecular assembly in the solid state, stereochemistry, and electronic states.…”
