All-polymer solar cells (all-PSCs) have recently made remarkable progress owing to the emergence of polymerized small molecule acceptors. However, the fabrication of all-PSCs featuring high efficiency, desirable photostability and excellent mechanical durability remains challenging. Herein, we designed and synthesized a series of novel non-volatile solid additives, namely DTC-Cn (n represents 8, 12

The threat of antimicrobial resistance to antibiotics requires a continual effort to develop alternative treatments. Arylglycines (or phenylglycines) are one of the signature amino acids found in many natural peptide antibiotics, but their propensity for epimerization in solid-phase peptide synthesis (SPPS) has prevented their use in long peptide sequences. We have now identified an optimized protocol

Two imine-riched polymers (planar P3Q and linear TDB) were synthesized through facile method. P3Q demonstrates enlarged π-conjugated structure, increasing the coordination and conversion of Zn2+. As a result, for aqueous zinc-ion batteries, P3Q exhibits more excellent electrochemical performance than TDB with an discharge capacity of 226 mAh g-1 at 0.3 A g-1 and relatively high capacity retention of

To unravel the role of driving force and structural changes in directing the photoinduced pathways in Donor-Bridge-Acceptor (DBA) systems, we compared the ultrafast dynamics in novel DBAs which share a phenothiazine (PTZ) electron donor and a Pt(II) trans-acetylide bridge (-C≡C-Pt-C≡C-), but bear different acceptors conjugated into the bridge (napthalene-diimide, NDI; or naphthalene-monoimide, NAP)

Polyamorphism has been a controversial and highly debated solid-state phenomenon in both material and pharmaceutical communities. Although some evidence of this fascinating phenomenon has been reported for several inorganic systems, and more recently also for a few organic compounds, the occurrence of polyamorphism is poorly understood and the molecular-level organization of polyamorphic forms is still

In organic chemistry, selecting mild conditions for transformations and saving energy are increasingly important for achieving sustainable development goals. Herein, we describe a red-light-mediated Barton decarboxylation using readily available red-light-emitting diodes as the energy source and zinc tetraphenylporphyrin as the catalyst, avoiding explosive or hazardous reagents or external heating

Straightforward calculations such as determinations of pKa values and N-basicities have allowed the development of a set of organometallic reactions for the regioselective functionalization of the underexplored fused N-heterocycle imidazo[1,2‑a]pyrazine. Thus, regioselective metalations of 6‑chloroimidazo[1,2-a]pyrazine using TMP-bases (TMP = 2,2,6,6-tetramethylpiperidyl) such as TMPMgCl‧LiCl and TMP2Zn‧2MgCl2‧2LiCl

We report the development of the first metallo-PROTAC, specifically a Pt-PROTAC, that can effectively degrade select Pt(II)-binding proteins. The Pt-PROTAC prototype successfully degraded thioredoxin-1 and thioredoxin reductase-1 in multiple myeloma cancer cell lines. Metallo-PROTACS will have important applications in the identification of metal binding proteins and as chemotherapeutic agents.

A visible light-induced kinetic controlled regioselective O-alkylation of various 1,3-dicarbonyl compounds with diazoacetates and cyclic ethers has been developed. The protocol provides a green and practical approach to highly stereoselective enol ethers under mild and base-free conditions in good to excellent yields.

We use in-situ neutron imaging to observe the adsorption/absorption of hydrogen within a packed catalyst bed of a Pd/C catalyst at a spatial and temporal resolution of 430 m and a 9 s respectively. Additionally, the H2/D2 exchange process across the catalyst bed is followed in real time.

Li-containing alloys and metallic deposits offer substantial Li+ storage capacities as alternative anodes to commercial graphite. However, the thermodynamically in sequence, yet kinetically competitive mechanism between Li solubility in the solid solution and intermediate alloy-induced Li deposition remains debated, particularly across the multiple scales. The elucidation of the mechanism is rather

Metal chloride complexes react with tris(trimethylsilyl)phosphine under mild condition to produce metal phosphide nanoparticles, and chlorotrimethylsilane as a byproduct. The formation of Si-Cl bonds that are stronger than the starting M-Cl bonds acts as a driving force for the reaction. The potential of this strategy is illustrated through the preparation of ruthenium phosphide nanoparticles using

The preparation of highly conductive media and the construction of conducting channels play a crucial role in improving the electrical conductivity of Electrically Conductive Adhesives (ECAs). Therefore, a new MXene structure is reported in this paper, and the improved structure is rationally designed by computational modeling, which greatly prevents the buildup of MXene nanosheets, improves the stability

Monoclonal antibodies (mAbs) hold promise for treating Parkinson's disease (PD), but their therapeutic use is hindered by poor delivery to the brain. In this study, we demonstrate that brain-targeted liposomes (BTL) enhance the delivery of mAbs across the blood-brain-barrier (BBB) and into neurons, thereby improving the intracellular and extracellular treatment of the PD brain. BTL were decorated with

Ultra-high-density single-atom catalysts (UHD-SACs) present unique opportunities for harnessing cooperative effects between neighboring metal centers. However, the lack of tools to establish correlations between the density, type, and arrangement of the isolated metal atoms with the support surface properties hinders efforts to engineer advanced material architectures. Here, we precisely describe the

Borophene-based van der Waals heterostructures have demonstrated enormous potential in the realm of optoelectronic and photovoltaic devices, which has sparked a wide range of interest. However, a thorough understanding of the microscopic excited-state electronic dynamics at interfaces is lacking, which is essential for determining the macroscopic optoelectronic and photovoltaic performance of borophene-based

Spin-polarized lasers, arising from stimulated emission of imbalanced spin populations, play a vital role in spin-optoelectronics. The achievement of spin-polarized lasing remains a long-lasting challenge, which is usually tackled by external spin injection, inevitably suffering from additional losses across the barriers from injection sources to gain materials. Herein, we report self-triggered spin-polarized

Rational selection and design of recombination electrodes (RCEs) are crucial to enhancing the power conversion efficiency (PCE) and stability of monolithic tandem solar cells (TSCs). Sputtered indium tin oxide (ITO) with high conductivity and excellent transmittance is introduced as RCE in perovskite/organic TSCs. To prevent high-energy ITO particles destroy the underlying material during sputtering

Hydrogenation reactions play a critical role in the synthesis of value-added products within the chemical industry. Electrocatalytic hydrogenation (ECH) using water as the hydrogen source has emerged as an alternative to conventional thermocatalytic processes for sustainable and decentralized chemical synthesis under mild conditions. Among various ECH catalysts, copper-based (Cu-based) nanomaterials

Excessive accumulation of reactive oxygen species (ROS) can lead to oxidative stress and oxidative damage, which is one of the important factors for aging and age-related diseases. Therefore, real-time monitoring and the moderate elimination of ROS is extremely important.
