which consists of two benzene molecules joined together by two nitrogen atoms linked by a double chemical bond.
The double bond prevents the benzene group at each end from rotating around the axle linking them.

The team's discovery comes after nearly a century of failed attempts by other labs to compress separate carbon-containing molecules like liquid benzene into an ordered diamond-like nanomaterial.
We used the large high-pressure Paris-Edinburgh device at Oak ridge National Laboratory to compress a 6-millimeter-wide amount of benzene a gigantic amount compared with previous experiments said Malcolm Guthrie of the Carnegie Institution for Science
The molecule they compressed is benzene a flat ring containing six carbon atoms and six hydrogen atoms.
During the compression process the scientists report the flat benzene molecules stack together bend and break apart.
That the atoms of the benzene molecules link themselves together at room temperature to make a thread is shocking to chemists and physicists.
when the benzene molecule breaks under very high pressure its atoms want to grab onto something else
This benzene then becomes highly reactive so that when we release the pressure very slowly an orderly polymerization reaction happens that forms the diamond-core nanothread.
Our discovery that we can use the natural alignment of the benzene molecules to guide the formation of this new diamond nanothread material is really interesting
But pentacene made of five benzene molecules joined in a line breaks down under normal environmental conditions.
Attempts to use polymers with benzene-like delocalised electron bonding alleviated issues around the thermal durability to a certain extent.
They used a fused ring system of molecules with benzene-like delocalised electron bonding so that the material would readily crystallise.
#'Parachuting'boron on benzene rings (Nanowerk News) Tuning the para position of benzene moieties is significant for creating biologically active compounds and optoelectronic materials.
Yet, attaching a functional handle specifically at the para position of benzene has been challenging due to multiple reactive sites on the ring.
Chemists at ITBM, Nagoya University have developed a novel iridium catalyst that enables highly para-selective borylation on benzene,
Itami and his coworkers have generated a new catalyst that uses steric interactions with the benzene substituent,
making it possible to conduct late stage diversification of core structures containing benzene. The study, published online on April 10, 2015 in the Journal of the American Chemical Society("para-CH Borylation of Benzene derivatives by a Bulky Iridium Catalyst),
The positions right next to the substituent on the benzene i e. the ortho-(2-or 6-)positions are blocked usually by the substituent during C-H borylation.
However, a mixture of meta-(3-or 5-)products and para-(4-)products are observed usually in a 2: 1 ratio upon C-H borylation of a monosubstituted benzene.
and materials science for creating benzene-containing functional molecules, I figured that para-selective C-H functionalization would be an extremely useful technique for the late-stage diversification of core structures.
Caramiphen, an anticholinergic agent used for the treatment of Parkinson's disease contains a monosubstituted benzene moiety along with ester and amine groups.
You have this polymer that s made from carcinogenic compounds like benzene and it will last up to 10,000 years.
refined form of the fuel"e-benzin"and claims that it burns clean due to its lack of sulfur and benzene.
And because their new fuel contains no benzene or sulphur they say it burns very cleanly.
enabling them to dissolve in solvents like benzene or toluene. The dysprosium complexes do not dissolve,
