Process of manufacturing benzobisthiazole building blocks for conjugated polymers

#Process for manufacturing a weak donor moiety which can be used in the synthesis of novel push-pull conjugated copolymers.

#A solar cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. It is a form of photoelectric cell (in that its electrical characteristics—e.g. current, voltage, or resistance—vary when light is incident upon it) which, when exposed to light, can generate and support an electric current without being attached to any external voltage source.

#The efficiency of a solar cell may be broken down into reflectance efficiency, thermodynamic efficiency, charge carrier separation efficiency and conductive efficiency. The overall efficiency is the product of each of these individual efficiencies.

#A more complete understanding of the present invention and benefits thereof may be acquired by referring to the follow description taken in conjunction with the accompanying drawings in which:

#FIG. 1a depicts a 1H NMR spectrum of 2,5-dihyxylbenzene-1,4-diamine in CDCl3.

#FIG. 1b depicts a ChemDraw-simulated 1H NMR spectrum of 2,5-dihyxylbenzene-1,4-diamine.asd

#Turning now to the detailed description of the preferred arrangement or arrangements of the present invention, it should be understood that the inventive features and concepts may be manifested in other arrangements and that the scope of the invention is not limited to the embodiments described or illustrated. The scope of the invention is intended only to be limited by the scope of the claims that follow.

#The current disclosure depicts a process of synthesizing 2,6-dibromo-4,8-dihexylebenzo[1,2-d:4,5-d′]bis(thiazole) from 2,5-dihyxylbenzene-1,4-diamine.

#In one embodiment 2,5-dihyxylbenzene-1,4-diamine is synthesized from 1,4-dibromohexyl benzene prior to synthesizing 2,6-dibromo-4,8-dihexylbenzo[1,2-d:4,5-d′]bis(thiazole).
