Herein, thermally responsive reversible chiral supramolecules are reported, constructed by the chirality transfer from tripeptides to achiral network supramolecular organic frameworks (SOF) based on configurationally stepping confinement, which displayed not only highly selective but also efficient enhanced near-infrared (NIR) luminescence. Taking advantage of macrocyclic CB[8] separately encapsulated two kinds tetracationic bis(phenothiazines) derivatives (G1, G2) at 2:1 stoichiometric form 2D SOFs, efficiently enhancing 12.6 fold NIR luminescence and blueshifted 705 680 nm for G1, redshifted 695 710 G2, respectively. Uncommonly, tripeptide coassembled with noncovalent (G1/CB[8] or G2/CB[8]) different opposite circular dichroism signals binding modes affinity, achieving assemblies further fluorescence up 46.2 times quantum yield (QY) increased 0.71% 10.29% G2/CB[8], showing tunable under thermal stimulus. Therefore, current research has achieved controllable SOFs enhancement fluorescence, is successfully applied in logic gates, information encryption, cell imaging.

Abstract Herein, we reported a biofuel‐driven recyclable chiral supramolecular transfer container based on hexacationic triphenylamine cage and nucleotides. Possessing rotatable paddle rigid backbones, the artificial receptor effectively encapsulated nucleotides with high binding constant up to 5.37×10 5 M −1 in water, displaying guest‐induced efficient fluorescence enhancement quantum yield increased from 6.5 % 16.6 %. Especially, achiral could bind adenosine triphosphate activate chirality substrates single molecular container, giving circularly polarized luminescence at 575 nm positive Cotton effect peaks significant asymmetric factor ( g abs =+6.4×10 −4 ). Meanwhile, adaptive supramolecule not only has reversible thermal responsiveness but also stepwise regulate by catalysis of hexokinase apyrase tandem, showing recovery after refueled, achieving dynamically regulated programmable multistate luminescent supramolecules. Therefore, be successfully applied logic gates multilevel information encryption, providing new insight into intelligent materials.
