The molecular formula C22H14 (molar mass: 278.36 g/mol) may refer to:
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C14H10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes. Anthracene is colorless but exhibits a blue (400–500 nm peak) fluorescence under ultraviolet radiation.
CR gas or dibenzoxazepine, or its chemical name dibenz[b,f][1,4]oxazepine, is an incapacitating agent and a lachrymatory agent. CR was developed by the British Ministry of Defence as a riot control agent in the late 1950s and early 1960s. A report from the Porton Down laboratories described exposure as "like being thrown blindfolded into a bed of stinging nettles", and it earned the nickname "firegas".
In chemistry, the organic compound triphenylene is a flat polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings. Triphenylene can be isolated from coal tar. It is also made synthetically by synthesis and trimerization of benzyne. One molecule of triphenylene has delocalized 18-π-electron systems based on a planar structure. It has the molecular formula C
18H
12.
A molecular switch is a molecule that can be reversibly shifted between two or more stable states. The molecules may be shifted between the states in response to environmental stimuli, such as changes in pH, light, temperature, an electric current, microenvironment, or in the presence of ions and other ligands. In some cases, a combination of stimuli is required. The oldest forms of synthetic molecular switches are pH indicators, which display distinct colors as a function of pH. Currently synthetic molecular switches are of interest in the field of nanotechnology for application in molecular computers or responsive drug delivery systems. Molecular switches are also important in biology because many biological functions are based on it, for instance allosteric regulation and vision. They are also one of the simplest examples of molecular machines.
Sir Ernest Laurence Kennaway FRS was a British pathologist and Royal Medal winner. He first became interested in natural life when, due to a childhood illness, he was encouraged to spend time outdoors. He was trained at University College London, and in 1898 was accepted into New College, Oxford on an open scholarship to study natural sciences. He graduated with a B.A. in 1903, and after three years at Middlesex Hospital he completed a Bachelor of Medicine and Surgery. After graduating he worked for The Lister Institute for Preventive Medicine and UCL before returning to Oxford, this time to Brasenose College on a Hulme scholarship in 1909. He became a Travelling Fellow of Brasenose in 1910, a Doctor of Medicine in 1911 and a Doctor of Science in 1915.

Dibenz[a,h]anthracene is an organic compound with the chemical formula C22H14. It is a polycyclic aromatic hydrocarbon made of five fused benzene rings. It is a fused five ringed, cyclopenta, PAHs compound which is common as a pollutant of smoke and oils. It is white to light yellow crystalline solid. It is stable and highly genotoxic in bacterial and mammalian cell systems, as it intercalates into DNA and causes mutations.
Dibenz[a,j]anthracene is an organic compound with the chemical formula C22H14.
A J-aggregate is a type of dye with an absorption band that shifts to a longer wavelength of increasing sharpness when it aggregates under the influence of a solvent or additive or concentration as a result of supramolecular self-organisation. The dye can be characterized further by a small Stokes shift with a narrow band. The J in J-aggregate refers to E.E. Jelley who discovered the phenomenon in 1936. The dye is also called a Scheibe aggregate after G. Scheibe who also independently published on this topic in 1937.
