Circularly polarized luminescence (CPL) has attracted tremendous attention because of its significant application prospect across multiple fields three-dimensional display, data storage, and information encryption. Chirality are two necessary prerequisites for the generation CPL. However, controlling these factors simultaneously in a rational manner remains challenge. Herein, we highlight recent advances on regulation CPL through new concept, named matching rules, mainly including fluorescence-selective absorption, circularly fluorescence energy transfer, chiral communication between excited state ground state. An important commonality among strategies is that they need good overlap corresponding spectra luminescent part (fluorescence, phosphorescence, or CPL) (organic, inorganic, organic-inorganic hybrid materials), which can be contactless separate. Different from most previous studies, no covalent noncovalent interactions parts required, makes them more facile convenient. Finally, summarize main advantages current challenges. We expect this concept to offer insightful novel understanding inspiration regulation.

Abstract Circularly polarized luminescence (CPL) plays a pivotal role in cutting‐edge display and information technologies. Currently achieving precise color control dynamic signal regulation CPL still remains challenging due to the elusory relationship between fluorescence chirality. Inspired by natural mechanisms governing formation chiral interaction, we proposed an addition‐subtraction principle theory address this issue. Three fluorene‐based polymers synthesized Suzuki polycondensation with different electron‐deficient monomers exhibit similar structures UV/Vis absorption, but distinct emissions intramolecular charge transfer. Based on this, precise‐color CPL‐active films are obtained through quantitative supramolecular co‐assembly directed addition . Particularly, ideal white‐emitting film (CIE coordinates: (0.33, 0.33)) is facilely fabricated high quantum yield of 80.8 % dissymmetry factor ( g lum ) 1.4×10 −2 Structural analysis reveals that ordered stacking orientation favors higher Furthermore, dynamically regulated challenge, comparable subtraction proposed, involving contactless communication excited ground states.

Abstract Although self‐assembly has emerged as an effective tool for fabricating biomaterials, achieving precise control over the morphologies and functionalities of resultant assemblies remains ongoing challenge. Inspired by copper peptide naturally present in human plasma, this study, we designed a synthetic precursor, FcGH. FcGH can self‐assemble via two distinct pathways: spontaneous Cu 2+ ‐induced. These assembly pathways enabled formation with tunable adjusting amount added . We found that nanoparticles formed ‐induced exhibited significantly higher cellular uptake efficiency than wormlike fibers spontaneously. Moreover, process occurred spontaneously at 1 : molar ratio to FcGH, avoiding excessive use tedious preparation procedure. By co‐assembling 10‐hydroxycamptothecin (HCPT)‐conjugated supramolecular nanodrugs elicited multiple cell death modalities cancer cells elevated immunogenicity, enhancing therapeutic effect compared free HCPT. This study highlights efficient directing synergistic tumor therapy.

Abstract Chirality‐driven self‐sorting plays an essential role in controlling the biofunction of biosystems, such as chiral double‐helix structure DNA from self‐recognition by hydrogen bonding. However, achieving precise control over self‐sorted structures and their functional properties for bioinspired supramolecular systems still remains a challenge, not to mention realizing dynamically reversible regulation. Herein, we report unprecedented saucer[4]arene‐based charge transfer (CT) cocrystal system with synergistically induced triangular macrocycle organic vapors. It displays efficient chain length‐selective vapochromism toward alkyl ketones due modulation optical vapor‐induced diverse structural transformations. Experimental theoretical studies reveal that unique vapochromic behavior is mainly attributed formation homo‐ or heterochiral assemblies different ketone guests, which differ dramatically solid‐state superstructures CT interactions, thus influencing properties.
