Patent ID: 7199167

Claim:
A light emitting or charge transporting polymer comprising a polymer formed from reactive mesogens having the formula: B—S—A—S—B wherein A is a chromophore of general formula —(Ar—Fl) n —Ar— wherein Ar is an aromatic diradical or a heteroaromatic diradical bonded linearly or substantially linearly to adjoining diradicals, or a single bond; Fl is a 9,9-dialkyl substituted fluorene diradical joined to adjoining diradicals at the 2 and 7 positions; the Ar and Fl diradicals may be chosen independently in each of the n subunits of the chromophore; and 1≦n≦10, S is a spacer; and B is an endgroup which is susceptible to polymerization.
