The tetracene , and naphthacene , is an aromatic hydrocarbon . It is a logical continuation of the benzene , naphthalene and anthracene series because it consists of four fused benzene rings.
properties
The solutions of tetracene fluoresce slightly green.
Representation and occurrence
Tetracene can be synthesized by reacting phthalic anhydride with corresponding naphthalene derivatives. A natural occurrence is coal tar , from which it can be obtained by distillation .
use
Tetracene is an organic semiconductor and it can be used in research to produce light-generating organic field effect transistors (OFET). However, there is no economically significant application as an optically active organic semiconductor.
Tetracene is also the starting product for dyes , although the route usually leads via the quinones . Tetracene is the main body of Rubren , the Tetracycline u. a. Antibiotics .
Likelihood of confusion
Tetracene can by name easily tetracene , a derivative of tetrazenes be confused, which is highly explosive.
