Manipulation of periodic micro/nanostructures in polymer film is great importance for academics and industrial applications anticounterfeiting. However, with the increasing demand on information security, materials time-dependent features are urgently required, especially material where same can appear more than once time scale. Here, one concise strategy to realize anticounterfeiting "double-lock" encryption based a host-guest system proposed, photoresponsive azopolymer as host...
Phase transition materials can be utilized in a variety of functionalization scenarios, benefiting from the photoinduced changes their physicochemical properties. Among them, small molecular crystals or liquid-crystalline polymers containing azobenzene moieties that show phototunable melting points glass temperatures, respectively, have proven to significant optically controlled functional materials. In recent years, they been successfully used reversible mechanical actuation, adhesion,...
Numerous anticounterfeiting platforms using photoresponsive materials have been designed to improve information security, enabling applications in technology. However, fabricating sophisticated micro/nanostructures bidirectional mass transport achieve advanced remains challenging. Here, we propose one strategy steerable a system with the assistance of solvent vapor at room temperature.

Human substance needsśś have been enriched by the development of smart-responsive materials possessing unique responsiveness and mechanical variability. However, acquiring these features in photoresponsive energy-driven elastomers is challengeable but highly desirable. Here, we report fabrication physically-crosslinked based on an aliphatic polycarbonate terminated with one azobenzene derivative as end group.

In recent years, liquid-crystalline polymers containing azobenzene moieties that show phototunable glass transition temperatures have been successfully applied in adhesion, reversible mechanical actuation, athermal nano-imprinting, self-healing, energy storage, and other applications. Unfortunately, the physical principles properties underlying dynamic equilibrium behaviors when both trans cis isomers are triggered simultaneously remain elusive, experiments challenging due to difference...
Until now, solar thermal energy storage within phase-change materials (PCMs) depends on π–π and van der Waals interactions to improve their miscibility, which often brings about finite enhancement of density. Here, we report one nanoconfinement approach density using microphase separation a block copolymer, allowing PCMs selectively disperse into nanodomains polymer film for use as fuel (STF). Upon doping certain amount photoinert organic with liquid-crystalline copolymer containing...
This study provides a universal approach for fabricating light powered autonomous self-oscillators by multiple regulation approaches, and broadens the potential applications of in signal transmission.
Molecular solar thermal fuels (MOSTs), especially azobenzene-based MOSTs (Azo-MOSTs), have been considered as ideal energy-storage and conversion systems in outer or confined space because of their "closed loop" properties. However, there are two main obstacles existing practical applications Azo-MOSTs: the solvent-assistant charging process high molar extinction coefficient chromophores, which both closely related to π-π stacking. Here, we report one efficient strategy improve energy...

Photoluminescence is one of the most meticulous ways to manipulate light energy. Typical photoluminescent emitters are mostly stable substances with a pure photophysical process spontaneous photon-emission from their excited states. Intermediate elusive attributing synchronous energy transfer including and incomplete photochemical pathways. An intermediate emitter containing radicals more difficult be observed due its inherent chemical reactivity. Here, these challenges overcome by...
The influence of various silicon contents on the grain refinement and crystal morphology pure aluminum Al-based alloy with low titanium content produced by electrolysis is comparatively investigated. nucleation behavior are studied SEM nucleants detected EDS. shows better response to content, especially high content. α-Al remains fine equi-axed structure even though increases 5%. This should be attributed potential nucleants. All might in type TiAl3 or Ti(Al1−X, SiX)3, but atomic fraction...
