DOI: 10.1002/adom.202401744

Abstract: The self‐assembled cellulose nanocrystal (CNC) film has a left‐handed layered structure, which makes the reflection of right‐handed circularly polarized (CP) light a challenge. Herein, a nematic phase layer is designed and inserted into the chiral… read more here.

DOI: 10.1002/chir.23556

Abstract: The chiral-induced spin selectivity (CISS) effect relates to the spin-selective electron transport through chiral molecules; therefore, the chiral molecules act as spin filters. In past studies, correlation was found between the magnitude of the spin… read more here.

DOI: 10.1021/acsami.1c24264

Abstract: Circularly polarized luminescence (CPL)-active materials with high dissymmetry factor (glum) values show great potential in photonic devices. In this study, electric-field-driven systems with tunable CPL signals are successfully fabricated based on polymer-stabilized cholesteric liquid crystal… read more here.

DOI: 10.1021/acsami.3c04353

Abstract: Developing circularly polarized room-temperature phosphorescent (CPRTP) materials with a high dissymmetry factor (glum) and long afterglow is very attractive but highly challenging. Here, a CPRTP emission featuring ultrahigh glum value and desired visualization characteristic in… read more here.

DOI: 10.1021/jacs.5c13847

Abstract: Unraveling the luminescence-structure relationship in metal-free chiral perovskites remains challenging, particularly for achieving both a strong circularly polarized luminescence (CPL) and high photoluminescence quantum yield (PLQY). Here, we attempt to decode this hidden linkage by… read more here.

DOI: 10.1039/d5sc07321a

Abstract: Cycloparaphenylenes (CPPs) with unique luminescent properties and well-defined dimensions are considered as ideal blocks for achieving excellent circularly polarized luminescence performance. Chiral CPPs face challenges in simultaneously achieving both high photoluminescence quantum yield (PLQY) and… read more here.
