Methods and systems of organic semiconducting polymers

Abstract:

A method of reacting bis(R.sub.1) 5,5'''-dibromo-3'',4'-difluoro-[2,2':5',2'':5'',2'''-quaterthiophene]-3,3- '''-dicarboxylate and bis(R.sub.2) 5,5'''-dibromo-3'',4'-difluoro-[2,2':5',2'':5'',2'''-quaterthiophene]-3,3- '''-dicarboxylate to form the polymer: ##STR00001## In this polymer R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are independently selected from the group consisting of: a halogen, a substituted alkyl, an unsubstituted alkyl, a substituted aryl, an unsubstituted aryl, a substituted heteroaryl and an unsubstituted heteroaryl.
