Intramolecular singlet fission in covalently linked pentacene and tetracene dimers has also been reported.
2.
Acenes, Pentacene and Tetracene in particular, are a prominent candidates for singlet fission.
3.
Being a fully benzenoid PAH means that triphenylene is much more benzo [ " c " ] phenanthrene, and tetracene.
4.
Jan Hendrik Sch�n during his time at Bell Labs ( 1997 2002 ) claimed to have developed an electrically pumped laser based on tetracene.
5.
Tetracene is a molecular organic semiconductor, used in organic field-effect transistors ( OFETs ) and organic light-emitting diodes ( OLEDs ).
6.
Tetracene is the four-ringed member of the series of acenes, the previous one being anthracene ( tricene ) and the next one being pentacene.
7.
However, high purity chrysene is colorless, the yellow hue being due to the traces of its yellow-orange isomer tetracene, which cannot be separated easily.
8.
In May 2007, researchers from two Japanese universities, Tohoku University in Sendai and Osaka University, reported an ambipolar light-emitting transistor made of a single tetracene crystal.
9.
In February 2014, NASA announced a greatly upgraded database for tracking polycyclic aromatic hydrocarbons ( PAHs ), including "'Tetracene "', in the universe.
10.
Structurally, pentacene is one of the linear acenes, the previous one being tetracene ( four fused benzene rings ) and the next one being hexacene ( six fused benzene rings ).
