Abstract:
1. An organic polymer having an elevated refractive index, the organic polymer having one or more five-member unsaturated cyclic structures within one or more polymer repeating units, wherein the one or more polymer repeating units are selected from polythiophenes, polypyrroles, polyfurans, polythiophene vinylenes, or combinations of two or more thereof and wherein the polymer is formed by a process comprising the steps of: providing a solution of unsaturated organic monomer units and boron trifluoride diethyl ether; impeding saturation of the unsaturated organic-monomer units by at least one protic element in the solution; polymerizing the unsaturated organic monomer units at a temperature within 20° C. of the freezing point of the boron trifluoride diethyl ether to form a conjugated organic polymer having a refractive index of at least about 2.3 for electromagnetic energy having a wavelength of about 700 nm; and collecting the conjugated organic polymer.
