Abstract Stimulus‐responsive fluorescent polymeric materials ( FPMs ) that can change their states via external stimuli have been widely applied in multi‐level information encryption and anti‐counterfeiting. While many efforts mainly focused on the design of dual‐stimuli responsive , construction orthogonal photo‐ thermo‐regulation systems remains a challenge. Here, thermo‐responsive hydrogels PTFPHs containing capsules with phase (PCMs), photoresponsive molecules (DTE), thermally (TPA‐DCPP) are reported. They capable reconfiguring fluorescence (none, green, yellow, red) thermo‐induced resonance energy transfer (FRET) process. Additionally, not only thermochromic property be regulated by modulating composition PCMs, but photochromic properties also tuned using SDS to control size capsules. The developed exhibited high contrast, fast response, excellent reversibility. successfully integrated application between temperature monitoring works represented strategy for developing multi‐stimuli advanced

The coordination of multiple luminescent centers in a simple and efficient way is difficult challenge for realizing the tunable multicolor function fluorescent hydrogels. In this work, we synthesized hydrogel with conversion via "one-pot method," which greatly simplifies tedious steps preparing luminescence intensity color DPA-Eu/TPE@PVA can be modulated by various stimuli, such as excitation wavelength, pH, presence Fe3+ ions. entire work on rational introduction light-emitting molecule tetrakis(4-hydroxyphenyl)ethylene (TPE-4OH) lanthanide ionic complex 2,6-pyridinedicarboxylic acid-Eu (DPA-Eu) into poly(vinyl alcohol) (PVA) polymer network. Since mechanisms these two molecules differ, former emitting light aid aggregation-induced emission (AIE) effect latter through energy transfer metal dynamic bonds, individual controlled independently under specific stimuli. realization fluorescence has contributed to its application fields sensors, probes, information encryption.

Surface wrinkling structures based on a bilayer system are widely employed in storing and encrypting specific optical information. However, constructing stable structure with high-level security remains an extensive challenge due to the delamination issue between skin layer substrate. Herein, double cross-linking strategy is introduced hydrogel doped fluorescent molecules polydimethylsiloxane establish interfacial dual-mode functionality, which light reflection of wrinkles fluorescence intensity can be simultaneously regulated by modulus ratio two layers. The spontaneous physically unclonable function enhance photoluminescence emission area under ultraviolet radiation. Meanwhile, constructed acrylamide acrylic acid copolymer protects patterns from loss detailed for authentication external damage. find potential applications fields information storage encryption.
