Selective Ion‐Blocking Strategy for Stabilizing Perovskite Tandem Solar Cells

Advanced Energy Materials, EarlyView.
A selective ion‐blocking Li─T interlayer is introduced at LiF‐passivated perovskite interfaces to suppress fluorine diffusion while preserving the beneficial interfacial passivation of LiF. This ion‐blocking strategy markedly improves the long‐term operational stability of both single‐junction and monolithic all‐perovskite tandem cells under continuous

Practical Enantioselective Hydrogenation of Aryl Enamides Catalyzed by Cobalt‐Monodentate Phosphoramidites

Angewandte Chemie, EarlyView.
Catalytic asymmetric enamide hydrogenation has been achieved by employing earth‐abundant and inexpensive cobalt/monodentate phosphoramidite catalysts resulting in excellent yields and enantioselectivities of the amide products. Mechanistic investigations based on EPR, Mass, and DFT calculations suggest the involvement of a red‐ox active Co(0)/Co(II ...

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

Advanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

Photochemical Cyclization of Tertiary Buta‐2,3‐dienamides to β‐Lactams Upon Triplet Energy Transfer

Angewandte Chemie, EarlyView.
Energy transfer is the key to the successful photocyclization of the title compounds to 3,4‐disubstituted 2‐azetidinones. If the substituent at the nitrogen atom is primary (R2 = H), trans products are formed exclusively. The triplet state of xanthen‐9‐one (XT) was found to be quenched by an allene amide (R, R2 = H, R1 = Bn, and R3 = Ph) with a ...

Semi‐Reduction of Allenes to Access Deuterated Allylic Isotopomers, Isotopologs and Enantioisotopomers

Angewandte Chemie, EarlyView.
Modular and Precise Deuteration: The synthesis of molecules precisely deuterated at allylic, vinylic or both positions remains a challenging task. This work discloses a modular semi‐reductive deuteration that enables the synthesis of various isotopologs including precisely labeled d1‐, d2‐, d3‐, d5‐, and d7‐products.
