Supramolecular frameworks obtained via self-assembly of proper elementary building units have received great attention, as they can express advanced functions uneasily expressed by the units. Until now, construction supramolecular has remained a challenging task, not to mention photoresponsive frameworks. Here, we report first framework (NUT-103) hierarchical zirconium metal–organic cages containing trinuclear clusters and azobenzene-functionalized ligands. NUT-103 displays permanent porosity reversible properties. Photoregulating adsorption CO2 was realized for regulation efficiency reach 55%, while that CH4 N2 is only 7% 3%, respectively. Grand Canonical Monte Carlo simulations demonstrate photoregulation property attributed variation capacity in interstitial region adjacent cages. Moreover, be dissolved form discrete recovered simple recrystallization. The similar behavior fresh sample.

Developing an artificial dynamic nanoscale molecular machine that dissipatively self-assembles far from equilibrium is fundamentally important but significantly challenging. Herein, we report self-assembling light-activated convertible pseudorotaxanes (PRs) show tunable fluorescence and enable deformable nano-assemblies. A pyridinium-conjugated sulfonato-merocyanine derivative (EPMEH) cucurbit[8]uril (CB[8]) form the 2EPMEH ⊂ CB[8] [3]PR in a 2:1 stoichiometry, which phototransforms into transient spiropyran containing 1:1 EPSP [2]PR when exposed to light. The thermally relaxes (reversibly) dark accompanied by periodic changes include near-infrared emission. Moreover, octahedral spherical nanoparticles are formed through dissipative self-assembly of two PRs, Golgi apparatus dynamically imaged using fluorescent

Development of robust multi-color photoswitchable fluorescent probes is critical for many optical applications, but it remains a challenge to rationally design these probes. Here, we report new Förster resonance energy transfer-based dual-color nanoparticles (DPF NPs) by taking advantage the distinct properties ligand-protected gold nanoclusters (AuNCs). Detailed photophysical studies revealed that ultrasmall-sized AuNCs not only act as FRET donors due their intrinsic fluorescence properties, also play significant role in regulating photochromic and aggregate spiropyran through ligand-spiropyran interactions. These DPF NPs exhibit high on/off ratio (∼90%) both green red emission, good reversibility during cycled photo-stimulation. Cell imaging experiments showed could specifically accumulate lipid droplets, enable living cells. Moreover, labeling mitochondria with green-emitting marker, demonstrated can distinguish different targets based on dynamic static signals at sub-cellular level two emission channels reliably. This study provides strategy designing modulating dyes nanoclusters, which be generalized development other photoswitch systems towards advanced applications.

The booming demand on data security has aroused great interest for developing smart materials with temporal display feature and dynamic multicolor fluorescence. However, it remains challenging to implement both features most responsive molecules. Herein, we construct a polymer free volume-controlled "molecular clock emitter" via covalently embedding multi-stimuli molecular switch (i.e., spiropyran) into network poly(pentafluorophenyl acrylate)) programmable crosslink density volume. By the aminolysis of pentafluorophenyl ester different amount diamine crosslinkers, pPFPA-co-SP networks controllable densities are generated, which have confinement effects rate constant SP/MC isomerization, thus leading time-dependent photochromism. In addition, PTF1, fluorescent probe that is sensitive rigidity, introduced further endow system phototunable full-color emission. Therefore, relying their synergistical responses rigidity network, successfully developed versatile emitter an "one stone two birds" manner, shows along fluorescence switching, providing potential advanced encryption anticounterfeiting high level.

Most elastomers undergo strain-induced crystallization (SIC) under tension; as individual chains are held rigidly in a fixed position by an applied strain, their alignment along the strain field results shift from strain-hardening (SH) to SIC. A similar degree of stretching is associated with tension necessary accelerate mechanically coupled, covalent chemical responses mechanophores overstretched chains, raising possibility interplay between macroscopic response SIC and molecular mechanophore activation. Here, thiol-yne-derived stereoelastomers doped covalently dipropiolate-derivatized spiropyran (SP) (0.25-0.38 mol%) reported. The material properties SP-containing films consistent undoped controls, indicating that SP reporter mechanical state polymer. Uniaxial tensile tests reveal correlations mechanochromism SIC, which strain-rate-dependent. When mechanochromic stretched slowly point activation, tethered remains trapped force-activated state, even after stress removed. Mechanophore reversion kinetics correlate rate, resulting highly tunable decoloration rates. Because these polymers not crosslinked, they recyclable melt-pressing into new films, increasing potential range strain-sensing, morphology-sensing, shape-memory applications.
