Facile Synthesis of 9,10-Diarylphenanthrenes and Poly(9,10-diarylphenanthrene)s

Fosong Wang, Klaus Müllen, Bo He, Hongkun Tian, Yanhou Geng
Organic Letters | 2008 | 10.1021/ol702873z

One-pot reduction of 9,10-diaryl-9,10-dihydrophenanthrene-9,10-diols to 9,10-diarylphenanthrenes was achieved with Zn/H + in acetic acid. Accordingly, various novel phenanthrenes and polyphenanthrenes with efficient blue emission were easily synthesized.

Carbon-based curiosities

Stuart Cantrill
Nature Chemistry | 2009 | 10.1038/nchem.219

Diamonds may be forever, but are some other forms of carbon merely passing fads? Stuart Cantrill considers why carbon often seems to be a chemist's best friend.

Crosslinked polymers: Healing power of the Sun

Anne Pichon
Nature Chemistry | 2009 | 10.1038/nchem.200

Materials that are able to mend themselves when damaged would make particularly good coatings in a variety of fields, including transportation, packaging and biomedicine. Investigations in this direction have been guided by the self-healing abilities of...

Short peptides self-assemble to produce catalytic amyloids

Yurii S. Moroz, William F. DeGrado, Caroline M. Rufo, Xiaozhen Hu, Jan Stöhr, Ivan V. Korendovych, Olesia V. Moroz, Tyler A. Smith
Nature Chemistry | 2014 | 10.1038/nchem.1894

Enzymes fold into unique three-dimensional structures, which underlie their remarkable catalytic properties. The requirement to adopt a stable, folded conformation is likely to contribute to their relatively large size (>10,000 Da). However, much shorter...

Pseudopterosin synthesis from a chiral cross-conjugated hydrocarbon through a series of cycloadditions

Andrew L. Lawrence, Samuel L. Drew, Christopher G. Newton, Michael N. Paddon-Row, Anthony C. Willis, Michael S. Sherburn
Nature Chemistry | 2015 | 10.1038/nchem.2112

The pseudopterosins are a family of diterpene marine natural products, which, by virtue of their interesting anti-inflammatory and analgesic properties, have attracted the attentions of many synthetic chemists. The most efficient syntheses reported to date...

Reactions at your fingertips

Jon T. Njardarson
Nature Chemistry | 2012 | 10.1038/nchem.1416

Smart phones and tablets have revolutionized how we communicate, access and use information, work, travel, play and learn. Chemistry education and the field of chemistry have not surprisingly been positively impacted by this technology…

Chiral information harvesting in dendritic metallopeptides

Hiroki Iida, Yuki Takeyama, Naoki Ousaka, Eiji Yashima
Nature Chemistry | 2011 | 10.1038/nchem.1146

Long-range communication of stereochemical information is common in biological systems, particularly in enzyme-catalysed reactions. Here, we report the remote control of the dynamic chirality of metal centres, coordinated by 2,2′-bipyridine ligands bearing...

Supramolecular dye aggregates: Nanotube knockout

Jürgen Köhler
Nature Chemistry | 2012 | 10.1038/nchem.1410

Organic molecular building blocks can self-assemble into structures with interesting optoelectronic properties. A combination of selective chemistry, spectroscopy and thorough theoretical analysis of a double-wall supramolecular nanotube has now led to a...

Gas separation: Marvellous MOFs

Gavin Armstrong
Nature Chemistry | 2008 | 10.1038/nchem.41

Metal–organic frameworks (MOFs) have garnered much attention because of their ability to adsorb gases, which can be tailored by tuning the pore size and MOF–adsorbate interactions through careful choice of ligand and metal. An example of such considered MOF...

Reductive amination: H2 free reduction

Enda Bergin
Nature Chemistry | 2014 | 10.1038/nchem.1940

Angew. Chem. Int. Ed. http://doi.org/f2qksb (2014) Many reductants are available to chemists, but molecular hydrogen is one of the most common both in academic labs and in industry. Though storage and transport can be a difficulty, hydrogen typically exhibits...

Sub-ångström-resolution crystallography reveals physical distortions that enhance reactivity of a covalent enzymatic intermediate

Karl M. Erixon, Ronald Kluger, Ralf Ficner, Kai Tittmann, Stefan Lüdtke, Piotr Neumann, Finian Leeper
Nature Chemistry | 2013 | 10.1038/nchem.1728

It is recognized widely that enzymes promote reactions by providing a pathway that proceeds through a transition state of lower energy. In principle, further rate enhancements could be achieved if intermediates are prevented from relaxing to their lowest...

Remote-controlled experiments with cloud chemistry

Richard A. Bourne, Jairton Dupont, Zacharias Amara, Raphael Horvath, Emilia Streng, Nigist Asfaw, Eduardo Pérez, Ryan A. Skilton, Jing Jin, Michael J. Scully, Guilherme L. P. Aydos, Jiawei Wang, Gurbuz Comak, Michael W. George, Martyn Poliakoff, Samantha L. Y. Tang, Peter A. Summers
Nature Chemistry | 2015 | 10.1038/nchem.2143

Developing cleaner chemical processes often involves sophisticated flow-chemistry equipment that is not available in many economically developing countries. For reactions where it is the data that are important rather than the physical product, the networking...
