Summary: Despite decades of research, shape-shifting molecular crystals have not yet become a primary class of actuating materials. To develop and commercialize these materials, it is essential to build an extensive knowledge base, which is currently scattered and disjointed for molecular crystal actuators. Using machine learning, we identify inherent features and structure-function relationships that impact the mechanical response of molecular crystal actuators. Our model considers different crystal properties and deciphers their combined effects on actuation performance, inviting interdisciplinary expertise to translate basic research into technology-based development.

Summary: In this study, an order recognition algorithm inspired by Schubert calculus was demonstrated using optical near-field statistics via nanometre-scale photochromism. The proposed algorithm successfully recognized the order of slot machines with unknown reward probabilities by utilizing Schubert polynomials generated from optical near-field patterns. Unlike conventional algorithms, this principle does not estimate reward probabilities but exploits the inversion relations contained in Schubert polynomials.

Summary: This study introduces a phototunable organic material with a golden luster. The material is produced using a photochromic diarylethene compound. By recrystallization, plate-like microcrystals are formed and laminated to create a film. The film exhibits a yellowish gold color through a combination of diarylethene absorption and specular reflection. Upon UV light irradiation, the color of the film changes to deep gold due to the photocyclization of diarylethene, and it reverts back to its original color under visible light exposure through photocycloreversion. The photoresponsive metallic luster of this material could have significant applications in the decoration and ink industries by eliminating the need for actual precious metals.

Summary: Green-to-blue triplet-triplet annihilation photon upconversion is used to drive reversible photoisomerization of diarylethene (DAE) photoswitches using visible light. By carefully selecting the molecular system and experimental geometry, a single green light source can selectively trigger ring-opening and ring-closing reactions. The upconversion solution and DAE solution can be characterized concomitantly and individually without further separation processes. The efficiency of ring-closing reaction using upconverted photons is compared to direct isomerization with ultraviolet light.

Summary: We report on the enhancement of the photoreaction and fluorescence of a newly synthesized photoswitchable fluorescent derivative through metal-ion gating. In the absence of metal ions, intramolecular photoinduced electron transfer (PET) suppresses the photoreactivity and fluorescence, while binding of a metal ion to an azacrown ether receptor blocks the PET process and significantly enhances the photoreactivity and fluorescence. Such molecules have the potential to function as metal-ion chemosensors and molecular probes in metal-ion-sensitive super-resolution fluorescence microscopy.

Summary: Drug-induced liver injury (DILI) is a common cause of acute liver failure in the USA and Europe, but most cases can be recovered or prevented by discontinuing the offending drug. Recent research has found that peroxynitrite (ONOO-) can be used as a potential indicator for early diagnosis of DILI, and there is an urgent need to establish a method to detect and track peroxynitrite in DILI cases. In this study, a FRET-based nano fluorescent probe CD-N-I was developed, which showed high selectivity and sensitivity in detecting peroxynitrite. The probe successfully detected exogenous peroxynitrite in live cells and endogenous peroxynitrite in APAP-induced liver injury of HepG2 cells.
