Abstract Amphiphilic cyclic dipeptides are efficient supramolecular hydrogelators. They can be combined with molecular photoswitches to produce light‐responsive soft materials, which applied in controlled drug delivery. Here it is reported that an arginine‐containing dipeptide decorated ortho‐fluorinated azobenzene forms hydrogels under physiological conditions reversibly liquefied upon exposure visible light frequencies (green and violet, respectively). The addition of sodium alginate results composite increased gelating capacity supported Coulombic interactions, also dissipate irradiation.

Donor-acceptor Stenhouse adduct (DASA) photoswitches have gained a lot of attention since their discovery in 2014. Their negative photochromism, visible light absorbance, synthetic tunability, and the large property changes between photoisomers make them attractive candidates over other commonly used for use materials with responsive or adaptive properties. The development such translation into advanced technologies continues to widely impact forefront research, DASAs thus attracted considerable interest field visible-light molecular switches dynamic materials. Despite this interest, there been challenges understanding complex behavior context both small molecule studies Moreover, incorporation polymers can be challenging due incompatibility conditions most common polymerization techniques. In review, therefore, we examine critically discuss recent developments DASA-containing polymers, aiming at providing better interplay properties constituents (matrix photoswitch). first part summarizes current DASA design switching second section discusses strategies materials, methods studying We also emerging applications polymeric ranging from light-responsive drug delivery systems, photothermal actuators, sensors photoswitchable surfaces. Last, summarize venture on steps required explore novel systems expand functional application opportunities polymers.

Azobenzenes (Ph-N═N-Ph) are known as the most widely studied molecular photoswitches, and recent rise of azoheteroarenes (Het-N═N-Ph or Het-N═N-Het) offers great opportunities to advance this already mature field. A common limitation is that azo-switches generally require harmful UV light for activation, which hinders their application across various fields. Despite efforts in developing visible-light azobenzenes over past few decades, potential heteroaryl azoswitches remains largely unexplored. This Perspective summarizes state-of-the-art advancements azoswitches, covering design strategies, structure-property relationship, applications. We highlight distinctive advantages research development switches. Furthermore, we discuss challenges emerging field propose solutions address crucial issues such spectral red-shift thermal half-life. Through paper, aim provide inspiration further exploration field, anticipation growing prosperity bright future azoheteroarene photoswitches.

Stimuli-responsive coordination polymers (CPs) are among one of the most prolific research areas in developing next-generation functional materials. Their capability being accurately excited by particular external changes with pre-determined and observable/characterizable behaviours correspond, so called "stimuli" "responsive". Abundant types CP compounds, especially metal-organic frameworks (MOFs), rocketing interest owing to their compositional diversity, structural tunability, essence highly engineerable functionality. This present review is aimed sketch several common stimulation corresponding responses for CPs, accompanied broad logic mechanisms underneath. And further from aspect material revolution, some representative progresses together latest advances CP-based materials various fields covered attempt display a broader picture towards possible prospects this topic.

Abstract Photoinduced transitions between the solid, glass, and liquid states based on molecular photoswitches promise a wide variety of applications. Photoswitchable adhesives are representative examples expected to contribute material recycling for sustainable future in era composite materials due strong bonding on-demand photo-induced debonding with minimal damage adherends. Only few known undergo these transitions, but recent progress, mainly azobenzene, has been remarkable.

Using smart photochromic and luminescent tissues in camouflage/cloaking of natural creatures has inspired efforts to develop synthetic stimuli-responsive materials for data encryption anticounterfeiting. Although many optical data-encryption have been reported, they generally require only one or a simple combination few stimuli decryptions rarely offer output corruptibility that prevents trial-and-error attacks. Here, we report series multiresponsive donor-acceptor Stenhouse adducts (DASAs) with unprecedented switching behavior controlled reversibility via diamine conformational locking substrate free-volume engineering their capability sequential logic (SLE). Being analogous the digital circuits, DASA gel-based system depends not on present input stimulus but also sequence past inputs. Incorrect inputs/sequences generate substantial fake information lead attackers point no return. This work offers new design concepts advanced operate SLE, paving path toward encryptions beyond circuit approaches.
