On May 13, 2015, Liu, Jun; Dou, Chuandong published a patent.Electric Literature of 75449-26-2 The title of the patent was Bis(boron-nitrogen-bridged) bipyridyl and organic/high polymer material prepared with the same. And the patent contained the following:
The present invention relates to a kind of bis(boron-nitrogen-bridged) bipyridyl (I, R1 is 4-20 alkyl group, R2, e.g., Ph, F, Et etc.), and organic/high polymer material prepared with the same, belonging to organic/high polymer area of solar cell. The object of the invention is to take classic pyrene unit as starting point to develop new BN receptor unit for further expanding receptor material system. The bis(boron-nitrogen-bridged) bipyridyl in this invention contains BN unit so that it has a number of advantages: such as complanation structure is conducive to orderly close accumulation of material mol., so as to increase mobility of material carrier; BN coordination has strong electron-drawing action, which is conducive to reducing mol. energy level; introducing alkyl chain with different lengths contributes to regulating material dissoly.; reaction site with functionalization can be used for preparing organic/high polymer material, and it has good application prospect if applied to solar cell. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Electric Literature of 75449-26-2
