Summary: A NaBr-assisted photoelectrochemical and photochemical integrated process was developed for complete isomerization of dimethyl maleate to dimethyl fumarate under solar-simulated light irradiation, producing bulky fumarate ester derivatives at high yields (85-100%). Results and calculations suggested a plausible mechanism of bromine-initiated radical chain reaction. The process achieved high faradaic efficiency (98%) and internal quantum yield (>100%), representing an innovative and environmentally friendly strategy for precise synthesis of fumarate derivatives under mild conditions.

Summary: Operationally simple strategies using visible light and a simple Lewis base are disclosed for the facile activation of α-halo boronic esters, leading to the construction of versatile E-allylic boronic esters via intermolecular addition to styrenes. This activation method can be strategically merged with selective energy transfer catalysis for the complimentary stereodivergent synthesis of Z-allylic boronic esters.

Summary: The study reveals a previously unknown molecular conformation-induced stress at the organic embedded interface using SFG spectroscopy technique. This stress, greater than 10 kcal/mol per nm(2), can cause molecular disorder in the organic semiconductor layer and ultimately lead to instability of the organic transistor. The research not only discloses interface stress in organic devices but also connects the instability of organic devices with interface stress for the first time, providing an effective solution for improving device stability.

Summary: In this study, we revealed the contra-thermodynamic E -> Z isomerization of alkenyl silanes by in situ formation of a chromophoric species, using rac-BINAP as the catalyst. The reaction, carried out in DMSO or CH3CN under irradiation at 405 nm, achieved the interconversion of E-isomers into Z-congeners with good to excellent yields and outstanding Z/E selectivities in 18 examples. Finally, the mechanism of the E -> Z isomerization was investigated to gain insights into the reaction mechanism.

Summary: The photocatalytic contra-thermodynamic E -> Z isomerization of vinyl boronates can be achieved using a binaphthol catalyst. The reaction proceeds through the transient formation of a suitable chromophore with a BINOL derivative as the catalyst, resulting in good-to-excellent Z/E ratio and excellent-to-quantitative yields. The mechanism involves the formation of a transient chromophore species.

Summary: The reduction of carbon dioxide is crucial for producing non-fossil-fuel-based feedstocks and mitigating greenhouse gas emissions. Amines play a critical role in these transformations, acting as CO2 trapping agents, proton shuttles, electron donors, and facilitators of CO2 reductions through formamide derivatives.

Summary: The molecular structure, near-infrared (NIR), and ultraviolet (UV) induced phototransformations of indazole-3-carboxylic acid were investigated in low temperature argon and nitrogen matrices using FTIR spectroscopy and B3LYP/6-311++G(2d,2p) calculations. Eleven stable structures were identified on the S0 potential energy surface, and the three most stable structures were confirmed experimentally in both matrices. NIR irradiation induced rotamerization within the carboxylic group, resulting in changes in the populations of trans 1HIC1 and cis 1HIC2 forms. UV irradiation at λ = 260 nm generated two new tautomers (2HIC2 and 2HIC3), indicating hydrogen atom transfer in the pyrazole ring. The obtained kinetic curves suggested differences in the phototransformation rates between different matrices.

Summary: This study demonstrates that (Z)-DVAM molecular crystalline microwires can exhibit continuous oscillatory motion when exposed to a combination of ultraviolet and visible light, mimicking the behavior of biological flagella. This is the first example of molecular crystals showing complex oscillatory behavior under continuous irradiation, with rotational frequency depending on light intensity and polarization.

Summary: The incorporation of pentiptycene scaffolds can enhance the performance of electrochromic polyamides, leading to lower driving potential, smaller redox potential difference, and shorter response time. The formation of intrinsic microporosity is a useful approach for the improvement of EC response performance.

Summary: This study demonstrates the concept of solid-state solvatofluorochromism by using an organogelator. The results show that the solvatofluorochromic green fluorescence protein chromophore located in the solid matrix near the liquid interface has better fluorescence stability, quantum efficiency, and solvatofluorochromicity compared to the one in the liquid phase. Additionally, fluorescence turn-on phenomenon occurs when the gel is formed in protic solvents. These features have been applied in various applications, such as multicolor fluorescence patterning, chemical vapor sensing, data encryption and decryption, and real-time fluorescence cell imaging.

Summary: The study reveals that the interplay between the thermal helical inversion of the stiff-stilbene moiety and the rotation of the dimethylamino group results in different kinetics of NMR signals in different states. Furthermore, the research shows that the phenomenon of switchable motion can be detected by the same set of NMR signals through photochemical switching.

Summary: In this work, a new rotation-inversion dual-motion molecular switch was reported. The kinetics of rotation and inversion were investigated using nuclear magnetic resonance signals. It was found that the correlation between the two motion modes differed in different molecular structures. Photochemical isomerization could switch the rate and correlation of the motion.

Summary: In this study, we investigated the third-order non-linear optical properties of four structurally unconstrained green fluorescence protein chromophores using experimental techniques and theoretical calculations. The results showed strong reverse saturable absorption and positive non-linear refractive index nature in these molecules under femtosecond pulse excitation. The third-order non-linear optical coefficients of these molecules were found to be larger than those reported in recent literature.

Summary: This study demonstrates the conversion of a polymorphic anthracene-pentiptycene pi-system into a pseudopolymorphic counterpart, which exhibits differences in fluorescence color and photodimerization activity depending on the polymorph. The five pseudopolymorphs share a common feature of columnar alkyl-pentiptycene threading mode but the specific structure is influenced by the size of the solvent included, resulting in two major types of pentiptycene-based frameworks.

Summary: A novel cis-stiff-stilbene c-2 a with high fluorescence quantum efficiency in acetonitrile (MeCN) is reported, which is attributed to a rigid stilbene backbone and a non-twisted meta-N,N-dimethylamino (DMA) substituent. This finding is important for understanding the meta-DMA effect in stiff-stilbene.

Summary: The position effect of the donor substituent on the formation of twisted intramolecular charge-transfer (TICT) state in aminostilbenes was studied. It was found that trans-3-(N,N-dimethylamino)-4' -cyanostilbene (mDCS) forms a TICT state in acetonitrile unlike its TICT-free para isomer DCS. The TICT state of mDCS involves twisting a C-C bond and differs from previously reported aminostilbenes which involve twisting a C-N bond.

Summary: Phenalenyl tiling, as a systematic structure design strategy, benefits the electron transport properties of open-shell graphene fragments with one free radical by reducing the on-site Coulomb repulsion effectively. The tiling inherits the desirable features of the phenalenyl radical in a predictable and delocalized fashion, making it a favorable candidate for charge transporting materials.
