The research in circularly polarized luminescence has attracted wide interest in recent years. Efforts on one side are directed toward the development of chiral materials with both high luminescence efficiency and dissymmetry factors, and on the other side, are focused on the exploitations of these materials in optoelectronic applications. This review summarizes the recent frontiers (mostly within five years) in the research in circularly polarized luminescence, including the development of chiral emissive materials based on organic small molecules, compounds with aggregation-induced emissions, supramolecular assemblies, liquid crystals and liquids, polymers, metal-ligand coordination complexes and assemblies, metal clusters, inorganic nanomaterials, and photon upconversion systems. In addition, recent applications of related materials in organic light-emitting devices, circularly polarized light detectors, and organic lasers and displays are also discussed.

“…Synthesized or self-assembled helical architectures not only provide artificial mimics for naturally occurring exquisite helices, such as double helix DNA and triple helix collagen 1 , but also advance the development of chiral functional materials by helical organization of varied building blocks including small organic molecules 2 – 7 , nanoparticles 8 , 9 , polymers 10 – 13 , ions 14 , and bio-macromolecules 15 . Among these intriguing hierarchically chiral structures, helical self-assembled π-architectures encoded with both chirality and luminescence characteristics might emit inequivalent left-handed or right-handed circularly polarized luminescence (CPL), which has attracted increasing attentions among chemistry and material science communities, because of its promising application prospects in the fields of next-generation displays and cutting-edge photonic technologies 16 – 24 .…”

Double helical π-aggregate nanoarchitectonics for amplified circularly polarized luminescence

et al. 2022

The canonical double helical π-stacked array of base pairs within DNA interior has inspired the interest in supramolecular double helical architectures with advanced electronic, magnetic and optical functions. Here, we report a selective-recognized and chirality-matched co-assembly strategy for the fabrication of fluorescent π-amino acids into double helical π-aggregates, which show exceptional strong circularly polarized luminescence (CPL). The single crystal structure of the optimal combination of co-assemblies shows that the double-stranded helical organization of these π-amino acids is cooperatively assisted by both CH-π and hydrogen-bond arrays with chirality match. The well-defined spatial arrangement of the π-chromophores could effectively suppress the non-radiative decay pathways and facilitate chiral exciton couplings, leading to superior CPL with a strong figure of merit (glum = 0.14 and QY = 0.76). Our findings might open a new door for developing DNA-inspired chiroptical materials with prominent properties by enantioselective co-assembly initiated double helical π-aggregation.

“…Taking the moderate number of SR ligands bridging those of [Ag 44 (SR) 30 ] 4− and [Au 44 (SR) 26 ] 2− into consideration, [Au x Ag 44− x (SR) 27 ] 3− is most probably formed by hetero-dimerization of [Ag 44 (SR) 30 ] 4− and [Au 44 (SR) 26 ] 2− , similar to the recently discovered hetero-dimeric structure of Au 29 (SR) 19 NCs composed of a half structure of Au 30 (SR) 18 and a half structure of Au 28 (SR) 20 . 45 It should be pointed out that the alloying reactions made possible by the apparent metal exchange between NCs with similar or identical structures ( e.g. , Ag 25 SR 18 /Au 25 SR 18 , and Au 38 (SR) 24 /Ag x Au 38− x (SR) 24 ) have been well demonstrated in the literature.…”
