Carbon-Carbon bonds: Hybridization
نویسنده
چکیده
Molecular binding behavior has a large in uence on the structure of a material and their properties. As a exclusion, carbon bind themself not in form of identical molecular orbitals but in form of hybridization. I explain the term hybridization and specify the in uence to the properties on the example of graphite and diamond. Furthermore, I present the change of properties by curvature e ects.

Structure and Applications of Single-Walled Carbon Nanotubes (SWCNTs) Synthesized Using the CoMoCAT Method
The unique properties of single-walled carbon nanotubes are a direct result of their distinctive structure, which is composed of C-C bonds more closely related to those in graphite than to those in diamond. That is, while diamond has a coordination number of four with sp hybridization, graphite involves three-coordinated carbons, in which three electrons are in sp hybridization and one is deloc...

Stable crystalline phosphorus ylides are obtained in excellent yields from the 1:1:1 addition reactionbetween hydantoins or thiohydantoins and dialkyl acetylenedicarboxylates in the presence oftriphenylphosphine. These phosphoranes undergo smooth intramolecular Wittig reaction followedby an electrocyclic ring opening to produce dialkyl (E)-2-(2,5-dihydro-5,5-diaryl-2-thioxo-1H-imidazol-4-yl)fum...
متن کاملCarbyne with finite length: The one-dimensional sp carbon
Carbyne is the one-dimensional allotrope of carbon composed of sp-hybridized carbon atoms. Definitive evidence for carbyne has remained elusive despite its synthesis and preparation in the laboratory. Given the remarkable technological breakthroughs offered by other allotropes of carbon, including diamond, graphite, fullerenes, carbon nanotubes, and graphene, interest in carbyne and its unusual...
متن کاملLarge “Pillow” Fullerenes Hydrogenated at the Inter-sheet “Seam”
In a previous paper on large “pillow” fullerenes, various systems were described with 12 pentagons connecting 2 parallel hexagonal arrays of benzenoid rings (graphene fragments functioning as the faces of the “pillow”) on top of each other. Additional bonds between these identical arrays formed only from sphybridized carbon atoms gave rise to hexagons and 12 pentagons along the “seam” or “rim.”...
متن کاملTopological Relationship Between One-Dimensional Box Model and Randić Indices in Linear Simple Conjugated Polyenes
The alternative double bonds and conjugation in the polyene compounds are one of the main properties in these compounds. Each carbon-carbon bonds in a polyene compound along the chain has appreciable double-bond character. The p-electrons are therefore not localized but are relatively free to move throughout the entire carbon skeleton as an one-dimensional box. The skeleton be considered as a r...
