The compounds consist of two benzene rings connected via a few carbon atoms as the body, four acetylene units each carrying an alkyl group at their ends which represents the hands and legs, and a 1,3-dioxolane ring as the head. Tour and his team at Rice University used the NanoPutians in their NanoKids educational outreach program.
1,2-Dioxin or 1,4-Dioxin, two unsaturated heterocyclic 6-membered rings in which two carbon atoms have been replaced by oxygen atoms, which gives the molecular formula C 4 H 4 O 2 Dibenzo-1,4-dioxin , also known as dibenzodioxin or dibenzo- p -dioxin (molecular formula C 12 H 8 O 2 ), in which two benzene rings are connected through two oxygen ...
For azepine, benzazepine is the preferred name. Likewise, the compounds with two benzene rings fused to the central heterocycle are carbazole, acridine, and dibenzoazepine. Thienothiophene are the fusion of two thiophene rings. Phosphaphenalenes are a tricyclic phosphorus-containing heterocyclic system derived from the carbocycle phenalene.
This group typically excludes compounds in which either benzene is fused to another ring (bicyclic, tricyclic, polycyclic) [1] or includes a heteroatom, or where the methane connects to three or four benzenes. Ball-and-stick model of the benzhydryl radical. The benzhydryl radical can be abbreviated Ph 2 CH• or Bzh. [2]
The molecular structure of grayanic acid consists of a depside skeleton with two benzene rings connected by both ester (-CO-O-) and ether (-O-) linkages, forming a depsidone. The molecule contains one methoxy group (H 3 CO-), one free hydroxyl group (-OH), and a chelated carboxyl group (-COOH).
Dibenzo-1,4-dioxin, also dibenzodioxin or dibenzo-p-dioxin (dibenzo-para-dioxin), is a polycyclic heterocyclic organic compound in which two benzene rings are connected by a 1,4-dioxin ring. Its molecular formula is C 12 H 8 O 2. The two oxygen atoms occupy opposite (para-) positions in the six-membered dioxin ring.
It is a polycyclic heterocyclic organic compound, since HpCDD contains multiple cyclic structures (two benzene rings connected by a 1,4-dioxin ring) in which two different elements (carbon and oxygen) are members of its rings. [1]
Dibenzazepine (iminostilbene) is a chemical compound with two benzene rings fused to an azepine ring. [1] Many pharmaceuticals, such as carbamazepine, oxcarbazepine, and depramine, are based on a dibenzazepine structure.
