Complex Organic Interstellar Molecules

Annual Review of Astronomy and Astrophysics, 2009
Of the over 150 different molecular species detected in the interstellar and circumstellar media, approximately 50 contain 6 or more atoms. These molecules, labeled complex by astronomers if not by chemists, all contain the element carbon and so can be called organic. In the interstellar medium, complex molecules are detected in the denser sources only.

Dynamic supramolecular complexation by shapeshifting organic molecules

Organic & Biomolecular Chemistry, 2009
The synthesis of bisporphyrin bullvalene 1 enabled explorations of its supramolecular complexation with C(60), revealing a dynamic network of interconverting complexes.

Complexation of small organic molecules by Cu+

Chemical Physics Letters, 1997
Abstract The structure and binding energetics have been computed for the complexes of Cu + with water, hydrogen sulfide, ammonia, formaldehyde, formimine, methanol, methanethiol, methylamine, formic acid and formamide, using ab initio and density functional methods.

Nanochannels: Hosts for the Supramolecular Organization of Molecules and Complexes

Langmuir, 2012
Nanochannels have been used as hosts for supramolecular organization for a large variety of guests. The possibilities for building complex structures based on 2D and especially 3D nanochannel hosts are larger than those based on 1D nanochannel hosts. The latter are, however, easier to understand and to control.

Complexes of Molecular Oxygen with Organic Molecules

Russian Chemical Reviews, 1985
Molecular oxygen forms complexes with organic molecules. Evidence for such complex formation and its manifestations are described and criteria are formulated whereby one can distinguish the usual equilibrium complexes from impact (collision) complexes. The principal types of complexes and the electron orbitals with the aid of which the species combined

Investigation of claims for interstellar organisms and complex organic molecules

Nature, 1984
For many years, Hoyle, Wickramasinghe and their associates have examined interstellar (IS) absorption features in the ultraviolet, visible and infrared and ‘identified’ them with a variety of organic structures or organisms. Among these there have been generalized, pre-biotic molecules1, polyoxymethylene whiskers2, polysaccharides and hydrocarbons3,4 ...
