Circularly polarized luminescence of syndiotactic polystyrene
Optical Materials, 2017 Abstract Syndiotactic polystyrene (s-PS) films, when crystallized from the amorphous state by temporary sorption of non-racemic guest molecules (like carvone) not only exhibit unusually high optical activity, both in the UV–Visible and Infrared ranges, but also present circularly polarized luminescence (CPL) with high dissymmetry ratios (g = ΔI/I ...

Advanced Science, EarlyView.A single‐molecule cascade supramolecular system comprising L/D‐FPy, CB[8], and SC4AD serves as an efficient light‐harvesting platform. It facilitates cascade energy transfer and chiral transfer to acceptor dyes. Co‐assembly with a PVA matrix produces a multicolor solid film that exhibits enhanced luminescence dissymmetry factors (glum), enabling ...

Scale effect of circularly polarized luminescent signal of matter
National Science Review, 2023 ABSTRACT Circularly polarized luminescence (CPL) is an important part in the research of modern luminescent materials and photoelectric devices. Usually, chiral molecules or chiral structures are the key factors to induce CPL spontaneous emission.

Atroposelective Construction of Axially Chiral Tetraarylethenes Via NHC‐Catalyzed Desymmetrization
Advanced Science, EarlyView.We report the first NHC‐catalyzed atroposelective synthesis of axially chiral TAEs via oxidative desymmetrization of prochiral TAE dialdehydes. This catalytic strategy operates under mild conditions and accommodates a broad range of phenolic and nitrogen nucleophiles, delivering diverse axially chiral TAEs in good yields and up to 99% ee.
