Erasable, Rewritable, and Reprogrammable Dual Information Encryption Based on Photoluminescent Supramolecular Host–Guest Recognition and Hydrogel Shape Memory

Advanced Materials, Год журнала: 2023, Номер 35(40)

Опубликована: Июнь 26, 2023

Information encryption technologies are very important for security, health, commodity, and communications, etc. Novel information mechanisms materials desired to achieve multimode reprogrammable encryption. Here, a supramolecular strategy is demonstrated multimodal, erasable, reprogrammable, reusable by reversibly modulating fluorescence. A butyl-naphthalimide with flexible ethylenediamine functionalized β-cyclodextrin (N-CD) utilized as fluorescent responsive ink printing or patterning on polymer brushes dangling adamantane group grafted hydrogels. The photoluminescent naphthalimide moiety bonded β-CD entrapped in the cavity. Its fluorescence highly weakened cavity recovers after being expelled from competing guest molecule emit bright green photoluminescence under UV. Experiments theoretical calculations suggest π-π stacking ICT primary mechanism naphthalimides assembly fluorescence, which can be quenched through insertion of conjugated molecules recover removing insert. Such reversible quenching recovering used repeated writing, erasing, re-writing information. Supramolecular recognition hydrogel shape memory further combined dual-encryption. This study provides novel develop smart improved security broad applications.

Supramolecular assembly activated single-molecule phosphorescence resonance energy transfer for near-infrared targeted cell imaging

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Июнь 5, 2024

Abstract Pure organic phosphorescence resonance energy transfer is a research hotspot. Herein, single-molecule system with large Stokes shift of 367 nm and near-infrared emission constructed by guest molecule alkyl-bridged methoxy-tetraphenylethylene-phenylpyridines derivative, cucurbit[n]uril ( n = 7, 8) β -cyclodextrin modified hyaluronic acid. The high binding affinity cucurbituril to molecules in various stoichiometric ratios not only regulates the topological morphology supramolecular assembly but also induces different emissions. Varying from spherical nanoparticles nanorods for binary assemblies, three-dimensional nanoplate obtained ternary co-assembly cucurbit[7]uril/cucurbit[8]uril, accompanying enhanced at 540 nm. Uncommonly, secondary acid activates single intramolecular process derived phenyl pyridines unit methoxy-tetraphenylethylene function group, enabling delayed fluorescence 700 nm, which ultimately applied mitochondrial targeted imaging cancer cells.

Self‐Assembled Nanocarrier Delivery Systems for Bioactive Compounds

Small, Год журнала: 2024, Номер 20(26)

Опубликована: Янв. 12, 2024

Abstract Although bioactive compounds (BCs) have many important functions, their applications are greatly limited due to own defects. The development of nanocarriers (NCs) technology has gradually overcome the defects BCs. NCs equally as BCs some extent. Self‐assembly (SA) methods build advantages than chemical methods, and SA significant impact on structure function NCs. However, relationship among mechanism, structure, not been given enough attention. Therefore, from perspective bottom‐up building concept SA‐structure‐function is emphasized promote SA‐based First, conditions forces for occurring introduced, then basis molecular mechanism protein, polysaccharide, lipid summarized. Then, varieties structures formed based introduced in detail. Finally, facing how be well solved by also elaborated. This review attempts describe great significance constructing artificial deliver aspects SA‐structure‐function, so wide application
