Fluorinated aromatic materials and their use in optoelectronics

A fluorinated aromatic compound of the formula:

• Ar—(R)x-(Q)y-(G)z,
• where Ar is an aromatic core including 3 to about 120 sp2 hybridized carbon atoms or a total of about 3 to about 120 sp2 hybridized carbon atoms, nitrogen atoms, oxygen atoms and sulfur atoms;
• R is a perfluoroalkyl group of the formula CnF2n+1, n is an integer ranging from 1 to about 30;
• Q is a perfluoropolyether group of the formula CkF2k+1Oh, k is an integer ranging from 1 to about 1000, h is an integer less than or equal to k−1;
• G is an organic functional group selected from the group consisting of hydrogen, C1-30 alkyl, C3-30 aryl, halogen, nitro, cyano, ester, ether, hydroxyl, aryl group bearing substituents including one or more of carbon, fluorine, chlorine, bromine, nitro or methoxy, or an aryl group including a heteroatom such as N, O and S;
• x, y and z are integers such that x+y+z is less than or equal to a total number of sp2 hybridized carbon atoms, nitrogen atoms, oxygen atoms and sulfur atoms in the aromatic core, and y and z may independently be zero.
