A correlation has been developed for corrected experimental C 1s XPS binding energies of polymers vs. calculated partial charges of carbon atom in model oligomers. Representative polymers containing a wide variety of heteroatoms such as Cl, F, O, N, Si have been selected. Molecular geometry was...
The chemistry of bridging methylene metal dimers and the value of the /sup 13/C NMR chemical shifts have been interpreted as due to a partial negative charge on the carbon atom. PES yields a C/sub 1s/ binding energy indicative of -0.5 e charge. However, for (..mu..-CH/sub 2/)(MnC...
A novel type of metastable complexes of metal (such as Na) atoms with a super-fluorinated carbon molecule is investigated, with a carbon atom exhibiting a unique, pentavalent character. It is induced by the charge transfer from the alkali metal component, followed by a geometric compression of ...
of the parent compound. The crystal structure of {[Zn(TCNQ)(4,4′-bpy)]·2benzene}nindicates that the benzene guests interact with the most negatively charged carbon atom of the TCNQ2−dianions via C–H⋯C-typehydrogen bonds, showing the existence of an electrostatic and/or CT ...
Charge carrier transport in organic semiconductors is at the heart of many revolutionary technologies ranging from organic transistors, light-emitting diodes, flexible displays and photovoltaic cells. Yet, the nature of charge carriers and their transpor
Describe the structure of an atom.An atom consists of a nucleus, which contains protons and neutrons, surrounded by electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The number of protons determines
(see Methods for more details). Interestingly, we observe that the polarization EDD mostly involves reorganization along the backbone carbon atoms of the decane. On the other hand, charge transfer appears as response of the electron density that is mainly localized on the hydrogen atoms of decane...
