Application No. 08/681,117
specification Holmes ‘809. We will therefore limit our discussion to the Holmes
‘809 reference.
We find Holmes is directed to a method for forming in a semiconductive
conjugated polymer at least first and second regions having different optical
properties. The invention also includes an electroluminescent device including a
semiconductive conjugated polymer comprising first and second regions having
different optical properties. The method of making a semiconductive conjugated
polymer comprises forming a layer of a precursor polymer and permitting the first
region to come into contact with a reactant, such as an acid, and heat while permitting
the second region to come into contact with a lower concentration of the reactant.
(Col. 2, ll. 8-19). The preferred precursor polymers include poly(para-phenylene- 1,2-
ethanediyl) polymer, a poly(2,5 dimethoxy para-phenylene-1,2-ethanediyl) polymer or
poly(thienylene-1,2-ethanediyl) polymer. (Paragraph bridging cols. 4-5). A suitable
precursor polymer is represented by Formula I which is converted to a partially
conjugated poly(arylenevinylene) polymer represented by Formula II. (Col. 14, ll. 1-
8). We find the polymer represented by Formula II of Holmes is a specie of the
poly(arylenevinylene) polymer represented by formula (I) of claim 1. Holmes does
not disclose irradiating the poly(arylenevinylene) polymer represented by Formula II
to form a pattern.
