Synthesis of ferrocene-containing six-membered cyclic ureas via alpha-ferrocenyl carbocations

, 2015
A series of ferrocene-containing six-membered cyclic ureas (1-aryl-4-ferrocenyl-3-phenyltetrahydropyrimidin-2(1H)-ones) was synthesized (in high-to-excellent yields) by reacting the corresponding amino-propanols with phenyl isocyanate and the subsequent ...

Solvent‐Desorption‐Induced Formation of a Long‐Period Polymorph Yielding a High‐Performance Porphyrin‐Based Organic Semiconductor

Advanced Science, EarlyView.
Solvent‐desorption‐induced structural transformation of 5,15‐bisphenyl‐tetrabenzoporphyrin generates a long‐period polymorph, in which the π‐stacking direction rotates by 90° between adjacent layers within the crystal while largely retaining crystallographic integrity.

Utilization of trihalogenated propanes by Agrobacterium radiobacter AD1 through heterologous expression of the haloalkane dehalogenase from Rhodococcus sp. Strain m15–3 [PDF]

, 1999
Trihalogenated propanes are toxic and recalcitrant organic compounds. Attempts to obtain pure bacterial cultures able to use these compounds as sole carbon and energy sources were unsuccessful.

Oxidative Cyclization of Amino Alcohols Catalyzed by a Cp*Ir Complex. Synthesis of Indoles, 1,2,3,4-Tetrahydroquinolines, and 2,3,4,5-Tetrahydro-1-benzazepine

, 2016
A new iridium-catalyzed oxidative cyclization of amino alcohols has been revealed. Indole derivatives are synthesized in good to excellent yields from 2-aminophenethyl alcohols by means of a [Cp*IrCl2]2/K2CO3 catalytic system.

Dual Randomness From Spatial and Temporal Variations in Stochastic Zinc Gallate Nanoclusters for PUF and TRNG Co‐Driven Image Generation

Advanced Science, EarlyView.
A dual‐randomness hardware platform is demonstrated by integrating PUF and TRNG functionalities into mixed‐ZGO nanoclusters. By leveraging spatial and temporal stochasticity, the mixed‐ZGO NCs device enables both unique identification and random signal generation.

A Biomimetic Solvatochromic Chip With Optimized Chemical Diversity for On‐Site Liquid Identification

Advanced Science, EarlyView.
A compact biomimetic photonic‐gustatory chip uses Hansen‐solubility‐parameter‐guided solvatochromic disks to create distinct color patterns in organic liquids. An optimized four‐disk array distinguishes solvent types, ratios, homologues, isomers, and alcoholic beverages. Coupled with smartphone imaging and deep learning, it identifies 80 liquid classes

Balancing Crystallization Kinetics and Lattice Strain Enables Thermally Stable Slot‐Die‐Coated Narrow‐Bandgap Perovskite Solar Cells

Advanced Science, EarlyView.
Unbalanced crystallization in mixed Sn‐Pb perovskites causes film defects and instability. CsPbI3 nanocrystals serve as nucleation seeds to regulate growth during slot‐die coating. Resulting solar cells retain 80% efficiency after nine thermal cycles. Operando GIWAXS confirms suppressed microstrain and lattice distortion, demonstrating that synergistic
