Rapid Access to an Enantioenriched Spiro Bisindole Directly from Indole and Acetone

Angewandte Chemie, EarlyView.
A catalytic enantioselective one‐pot “self‐assembly” strategy was developed for the exceedingly convenient access to a spiro bisindole directly from indole and acetone. The obtained enantiopure C2‐symmetric bisindole showed exceptional performance as a chiral backbone of diverse effective catalysts or ligands. Abstract Disclosed here is a “one‐pot self‐

Photochemical Rearrangement of 8- methyl Spiro [2.5] oct-7-en-4-one to 4-methyl Spiro [2.5] oct-4-en-6-one [PDF]

Journal of Sciences, Islamic Republic of Iran, 1989
Irradiation of &methyl spiro [2.5] oct-7-en-4-one through its singlet excited state resulted in the formation of 4-methyl spirO [2.5] oct-4-en -6-one. We have used the cyclopropyl moiety in the molecule as a probe to study the operating mechanism in the

Enhancing Stability of Inverted Perovskite Solar Cells via Buried Interface Modification Using In‐Situ Crosslinked Thiol‐Ene Polymer

Advanced Energy and Sustainability Research, EarlyView.
Two crosslinkable molecules are introduced into the buried interface of perovskite to regulate the interfacial contact between [2‐(3,6‐dimethoxy‐9H‐carbazol‐9‐yl)ethyl]phosphonic acid and perovskite. The cross‐linked interfacial layer can control the crystallization process of the perovskite thin film and adjust the energy level alignment.

The cofinal property of the Reflexive Indecomposable Banach spaces [PDF]

arXiv, 2010
It is shown that every separable reflexive Banach space is a quotient of a reflexive Hereditarily Indecomposable space, which yields that every separable reflexive Banach is isomorphic to a subspace of a reflexive Indecomposable space. Furthermore, every separable reflexive Banach space is a quotient of a reflexive complementably $\ell_p$ saturated ...

Brane singularities with a scalar field bulk [PDF]

arXiv, 2010
The singularity structure and the corresponding asymptotic behavior of a 3-brane coupled to a scalar field in a five dimensional bulk is analyzed in full generality, using the method of asymptotic splittings. It is shown that the collapse singularity at a finite distance from the brane can be avoided only at the expense of making the brane world-volume

A Refined Dual‐Fiber Network Morphology as Printable Hole Transport Layers for High‐Performance Perovskite Solar Mini‐Modules

Aggregate, EarlyView.
To address the problems of uneven printing of the hole transport layers (HTLs) and the instability of the device due to the HTLs, we propose a dual‐fiber network structure (DFNS) strategy based on polymer HTLs. This strategy involves the spontaneous interweaving of micron‐sized fiber crystals to create efficient carrier transport channels.

Stationary disks and Green functions in almost complex domains [PDF]

arXiv, 2011
Using generalized Riemann maps, normal forms for almost complex domains (D, J) with singular foliations by stationary disks are defined. Such normal forms are used to construct counterexamples and to determine intrinsic conditions, under which the stationary disks are extremal disks for the Kobayashi metric or determine solutions to almost complex ...
