bis(tetrafluoroborate) (AccufluorTM NFTh) was effectively used for selective fluorination of polycyclic aromatics. Naphthalene was site-selectively fluorinated to 1-fluoronaphthalene, phenanthrene to 9-fluorophenanthrene, and pyrene to 1-fluoropyrene. In a series of substituted naphthalenes the regioselectivity and effectiveness of fluorination depended on the position and the nature of the substituents.

Room -temperature fluorination of benzene with cesium fluoroxysulphate in the presence of boron trifluoride as catalyst resulted in the formation of fluorobenzene, while reaction with naphthalene gave 1-fluoro and 2-fluoronaphthalene in the ratio 5:1, the overall yield being between 38 and 42%. The fluorination of phenanthrene and pyrene should be carried out at higher dilution and needs no catalyst
The present teachings relate to organic semiconductor formulations including an organic semiconducting compound in a liquid medium, where the liquid medium includes (1) a compound in liquid state that has electronic properties complementary to the electronic structure of the organic semiconducting compound and optionally (2) a solvent or solvent mixture for solubilizing the organic semiconducting compound. The present formulations can be used as inks in the fabrication of organic semiconductor devices.
