Precise organization of organic molecules into homochiral double-helix remains a challenge due to the difficulty in controlling both self-assembly process and chirality transfer across length scales. Here, we report that type bisnaphthalene bisurea molecule could assemble chirality-controlled nanoscale double-helices by supramolecular rosette-intermediated hierarchical mechanism. A solvent-mixing protocol is adopted direct cyclization chiral discrete rosettes through cooperative intramolecular intermolecular hydrogen bonds. Controlled hexagonal packing at higher concentrations gives one-dimensional single-stranded nanofibers, which intertwine well-defined nanostructures with preferred depends on absolute configurations bisurea. The enables effective excitation energy delocalization within double-helix, contributes near-unity from adsorbed acceptor dyes even donor/acceptor ratios over 1000, leading bright circularly polarized luminescence originally achiral acceptor. experimental theoretical simulation results not only provide strategy fabricate but also bring insights understanding high-efficiency light-harvesting photosystem II.

Abstract We demonstrate an electrostatic confinement‐induced charge transfer pathway in a supramolecular photocatalyst comprising of ionic covalent organic framework (COF) and cationic metal complexes. The dynamic interactions not only attract cations around the COF to accept photogenerated electrons, but also allow for retention homogeneous catalytic characters complexes, making subtle balance. Accordingly, confinement effect facilitates forward electron from photoexcited Co complex, realizing remarkable photocatalytic CO 2 reduction performance. Its efficiency is far superior counterparts with Van‐der‐Waals or hydrogen bonding interactions. This work presents insight enhancing systems, provides effective approach construction highly efficient photocatalysts.

Abstract Carbonized polymer dots (CPDs) exhibiting tunable solid‐state emission (SSE) show great promise as rare‐earth‐free functional phosphors. Nevertheless, progress in this field has been hindered by the structural heterogeneity of CPDs and a lack fundamental understanding underlying mechanisms. In work, universal approach is presented for large‐scale, controlled synthesis with tailored SSE properties. This strategy leverages intraparticle Förster resonance energy transfer (FRET) incorporating selected fluorophores into self‐assembled nanostructures. The resulting exhibit exceptional characteristics, such high quantum yields, adjustable band structures, narrow linewidths, excellent photostability both solution solid‐state. Moreover, multifunctional capabilities these are demonstrated, including efficient light harvesting, their potential nanocarriers, application light‐emitting diodes (LEDs). findings establish self‐assembly‐mediated doping robust platform engineering unique properties, underpinned principles FRET.
