Organic Microcrystal Vibronic Lasers with Full‐Spectrum Tunable Output beyond the Franck‐Condon Principle

17-Jan-2018 | Yong Sheng Zhao, Haiyun Dong, Chunhuan Zhang, Yuan Liu, Yongli Yan, Fengqin Hu, Angewandte Chemie International Edition, 2018

The very broad emission bands of organic semiconductor materials are, in theory, suitable for achieving versatile solid state lasers; however, most of organic materials only lase at short wavelength corresponding to the 0−1 transition governed by the Franck‐Condon (FC) principle. Here we develop ...

CO2‐Triggered Switchable Hydrophilicity of Heterogeneous Conjugated Polymer Photocatalyst for Enhanced Catalytic Activity in Water

17-Jan-2018 | Jeehye Byun, Wei Huang, Di Wang, Run Li, Kai A. I. Zhang, Angewandte Chemie International Edition, 2018

Water‐compatibility of heterogeneous photocatalysts has been pursued for energy and environmental applications. However, there exists a trade‐off between hydrophilicity and recyclability of the photocatalyst. Herein, we report a conjugated polymer photocatalyst with tertiary amine terminals that ...

Tuning the adsorption energy of methanol molecules along Ni‐N‐doped carbon phase boundaries via the Mott‐Schottky effect for highly efficient dehydrogenation of gas‐phase methanol

17-Jan-2018 | Zhong-Hua Xue, Jing-Tan Han, Wei-Jie Feng, Qiu-Ying Yu, Xin-Hao Li, Markus Antonietti, Jie-Sheng Chen, Angewandte Chemie International Edition, 2018

Engineering the adsorption of molecules on active sites is an integral and challenging part for the design of highly efficient transition‐metal‐based catalysts for methanol dehydrogenation. Here we report a Mott‐Schottky catalyst composed of Ni nanoparticles and tailorable nitrogen‐doped ...

A Stable Room‐Temperature Luminescent Biphenylmethyl Radical

17-Jan-2018 | Xin Ai, Yingxin Chen, Yuting Feng, Feng Li, Angewandte Chemie International Edition, 2018

Abstract There is only one family of room‐temperature luminescent radicals, the triphenylmethyl radicals, to date. Herein, we synthesize a new stable room‐temperature luminescent radical, (N‐carbazolyl)bis(2,4,6‐tirchlorophenyl)methyl radical (CzBTM), which has improved properties compared to ...

Development of Antibody‐Directed Therapies: Quo Vadis?

17-Jan-2018 | Tiago Rodrigues, Gonçalo J. L. Bernardes, Angewandte Chemie International Edition, 2018

Less is more: The efficacy of antibody–drug conjugates (ADCs) for cancer therapy is traditionally associated with cleavable linkers for payload release. Evidence now suggests that simpler constructs without cleavable moieties can afford more stable and effective ADCs.

IR Spectrum and Structure of Protonated Monosilanol: Dative Bonding between Water and the Silylium Ion**

17-Jan-2018 | Martin Andreas Robert George, Nguyen Xuan Truong, Marco Savoca, Otto Dopfer, Angewandte Chemie International Edition, 2018

We report the spectroscopic characterization of protonated monosilanol (SiH3OH2+) isolated in the gas phase, thus providing the first experimental determination of the structure and bonding of a member of the elusive silanole family. The SiH3OH2+ ion is generated in a silane/water plasma ...

Halogen Bonding in Solution: From Anion Recognition through Templated Self‐Assembly to Organo‐catalysis

17-Jan-2018 | Ulrich S. Schubert, Ronny Tepper, Angewandte Chemie International Edition, 2018

The halogen bond is a supramolecular interaction between a Lewis‐acidic region of a covalently bound halogen and a Lewis base. It has been studied widely in silico and experimentally in the solid state; however, solution phase applications have attracted enormous interest in the last years. This ...

Pd‐Catalyzed Atom Transfer Radical Cyclization at Remote Unactivated C(sp3)‐H Sites Enabled by Hydrogen Atom Transfer of Hybrid Vinyl Pd‐Radical Intermediates

17-Jan-2018 | Vladimir Gevorgyan, Maxim Ratushnyy, Marvin Parasram, Yang Wang, Angewandte Chemie International Edition, 2018

A novel mild, visible light‐induced Pd‐catalyzed hydrogen atom translocation/atom transfer radical cyclization (HAT/ATRC) cascade has been developed. This protocol involves a 1,5‐HAT process of previously unknown hybrid vinyl Pd‐radical intermediates leading to iodomethyl carbo‐ and heterocyclic ...
