ABSTRACT:
Provided herein is an inorganic-organic hybrid conjugated polymer having opto-electronic function and a process to make the same. The disclosed polymer contains inorganic or organic bulky groups in the polymer backbone or as pedant groups and has a general formula:wherein:A is a bulk group, comprising at least one silsesquioxane, serving as a positional anchor for the polymer. S serving as a spacer includes alkyl, cycyloalkyl group of from 1 to 30 carbon atoms, or aryl or substituted aryl of from 6 to 50 carbon atoms, or herteroaryl or substituted heteroaryl of from 4 to 50 carbons. CP represents any conjugated polymer segment at least one portion thereof comprising an opto-electronic function, for example, polyacetylenes, polyphenylenes, polyphenylenevinylenes, polythiophenes, polypyrroles, polyanilines, polyfluorences, and any conjugated co-polymer segment. x, y and z are positive integers, where x and z is equal or greater than 1. These integers determine the configuration of such a hybrid polymer system as expressed in the above formula.
