GENERAL
DESCRIPTION & APPLICATIONS
|
Violanthrene
is a polycyclic aromatic hydrocarbon (nine-benzene ring
compound). It has the appearance of a blue
crystalline powder. In structure it has enough solid bonds to store electrochemical
energy and is a molecule of organic semiconductor. Violanthrone (5,10-Violanthrenedione,
C.I. Vat Blue 20)
is a subject of research for use in organic thin film
transistors and OFETs. Violanthrone is a moiety of vat dye, which is resistant to
photochemical damage. It is an emitter of bright chemiluminescence. The excited molecule transfers its electrochemical energy in certain phase of chemical
reaction to sensitiser, which makes the sensitiser visible. Dihydroxyviolanthrone
is a moiety for green vat dyes.
Substituted violanthrones and isoviolanthrone (C.I. Vat Violet 10)
are
used in the preparation of fluorescent dyes which are used in the detection
of crude oil in depleted wells, pipeline interface,
the source of a leak and identifying petroleum fuels.
