With the fast development of organic electronics, semiconductors have been extensively studied for various optoelectronic applications, among which phototransistors recently emerged as one most promising light signal detectors. However, it is still a big challenge to endow with both high mobility and light-sensitivity because low photoresponsive materials limits efficiency transporting collecting charge carriers. We herein report band-like transport in vacuum-deposited small-molecule thin...
Some molecular photoisomers can be isomerized to a metastable high-energy state by exposure light. These molecules then thermally or catalytically converted back their initial state, releasing heat in the process. Such reversible photochemical process has been considered for developing solar thermal (MOST) systems. In this review, we introduce concept, criteria, and state-of-the-art of MOST systems, with an emphasis on three most promising systems: norbornadiene/quadricyclane,...
Discovering physicochemical principles for simultaneous harvesting of multiform energy from the environment will advance current sustainable technologies. Here we explore photochemical phase transitions-a photochemistry-thermophysics coupled regime-for coharvesting solar and thermal energy. In particular, show that photon ambient heat can be stored together released on demand as high-temperature heat, enabled by room-temperature crystal↔liquid transitions engineered molecular photoswitches....
The ever-increasing demand for flexible electronics calls the development of low-voltage and high-mobility organic thin-film transistors (OTFTs) that can be integrated into emerging display labeling technologies. Polymer dielectrics with comprehensive balanced dielectric properties (i.e., a good balance between their insulating characteristics compatibility semiconductors) are considered particularly important this end. Here, we introduce simple but highly efficient strategy to realize...
Molecular photoswitches (e.g., azobenzenes) can reversibly interconvert between their thermodynamically stable and metastable isomers upon light irradiations. However, it remains challenging to integrate both high bidirectional photoconversion long metastable-state lifetime into a photoswitchable functionality. Here, we introduce pyrazolylazophenyl ethers (pzAzo ethers) as class of azo that provides quantitative (>98 %) trans-cis photoisomerization (365 nm light), near-quantitative (95-96...
Abstract Azobenzenes are classical molecular photoswitches that have been widely used. In recent endeavors of design, replacing one or both phenyl rings with heteroaromatic has emerged as a strategy to expand diversity and access improved photoswitching properties. Many mono‐heteroaryl azo molecules unique structures and/or properties developed, but the potential bis‐heteroaryl architectures is far from fully exploited. We report family azobispyrazoles, which combine (near‐)quantitative...
Photochemical crystal ↔ liquid transitions (PCLTs) are interesting phenomena that couple reversible photochemical transformations with thermophysical phase transitions. A potential application of PCLTs is the development photoresponsive smart materials capable exerting adhesion capacities on specific surfaces at a desired timing, which unattainable for conventional adhesives. However, PCLT-based adhesives generally use UV light as stimulus, could lead to degradation and health problems....
Molecular solar thermal (MOST) materials, which can efficiently capture energy and release it as heat on demand, are promising candidates for future personal management (PTM) applications, preferably in the form of fabrics. However, developing MOST fabrics with high energy-storage capacity stable working performance remains a significant challenge because low density molecular materials their leakage from fabric. Here, an efficient robust fabric PTM using azopyrazole-containing microcapsules...

Photochemical molecular thermal storage systems coupled with phase change behavior (MOST-PCMs) offer unique opportunities capture regulate temperature. Here, we demonstrate how series visible-light-responsive azopyrazoles couple MOST PCMs provide release below 0 °C. The system charged by blue light at -1 °C, discharges in...
Natural photoactive systems have evolved to harness broad-spectrum light from solar radiation for critical functions such as perception and photosynthetic energy conversion. Molecular photoswitches, which undergo structural changes upon absorption, are artificial tools widely used developing photoresponsive converting energy. However, photoswitches generally need be activated by of specific narrow wavelength ranges effective photoconversion, limits their ability directly work under sunlight...
The development of light-responsive chemical systems often relies on the rational design and suitable incorporation molecular photoswitches such as azobenzenes. Linking a photoswitch core with another π-conjugated entity may give rise to intramolecular electronic coupling, which can dramatically impair function. Decoupling strategies have been developed based additionally inserting linker that disrupt through-bond communication. Here we show 1,2,3-triazole—a commonly used decoupling...
There is an urgent need for alternative compact technologies that can derive and store energy from the sun, especially large amount of solar heat not effectively used power generation. Here, we report a combination solution- neat-film-based molecular thermal (MOST) systems, where be stored as chemical released heat, with microfabricated thermoelectric generators to produce electricity when radiation available. The photophysical properties two MOST couples are characterized both in liquid...
Following the progress on mono-heteroaryl azo switches (Het-N=N-Ph), a few bis-heteroaryl (Het-N=N-Het) have been studied recently, whereas nonsymmetric ones (Het1 -N=N-Het2 ) that can combine respective merits of each heterocycle, received little attention. Here we report thiazolylazopyrazoles as visible-light switching character thiazole ring and ease o-substitution pyrazole ring. Thiazolylazopyrazoles achieve (near-)quantitative isomerization in both directions long Z-isomer thermal...
Phase change materials (PCMs) show great promise for thermal energy storage and management. However, some critical challenges remain due to the difficulty in tuning solid–liquid phase transition behaviors of PCMs. Here we present optically-controlled tunability transitions photoswitchable PCMs (ps-PCMs) synthesized by decorating molecular structure long-chain alkanes with a photo-induced isomerization unit. The dual reversible have remarkable differences melting/crystallization points, which...

The development molecular photoswitches that can be directly activated by imperative for unlocking full potential solar addressing growing demands. Herein, we designed series 2‐ amino ‐1,3‐bis‐azopyrazoles featuring coupled π n system, resulting pronounced redshift their spectral absorption, reaching up to 661 nm red region....
Flue gas mercury removal is mandatory for decreasing global background concentration and ecosystem protection, but it severely suffers from the instability of traditional demercury products (e.g., HgCl2, HgO, HgS, HgSe). Herein, we demonstrate a superstable Hg3Se2Cl2 compound, which offers promising next-generation flue strategy. Theoretical calculations revealed Hg bonding structure in Hg3Se2Cl2, with highest dissociation energy (4.71 eV) among all known compounds. Experiments its...
