About
Description: This application claims benefit of priority to provisional U.S. Patent Application Ser. No. 61/597,273 filed Feb. 10, 2012, which is incorporated by reference, to the same extent as though fully replicated herein.This invention was made with government support under grant number DMR0820579 awarded by the National Science Foundation. The government has certain rights in the invention.The present disclosure generally relates to improved organic semiconductors and improved organic photovoltaics using liquid crystalline bent-core molecules in a B4 subphase. Background: There are three common states of matter, solid, liquid, and gas. Liquid crystal (LC) is a fourth state that certain kinds of matter can enter into under the right conditions. Molecules in solids exhibit both positional and orientational order. The molecules are constrained to point only certain directions and to be only in certain positions with respect to each other. In liquids, the molecules do not have any positional or orientational order, the direction the molecules point and their positions are random. The liquid crystal phase exists between the solid and the liquid phase. The molecules in liquid crystal may or may not possess any positional order, but they do possess a certain degree of orientational order. The molecules do not all orient the same direction all the time, they just tend to orient more in one direction over time than other directions. This direction is referred to as the director of the liquid crystal.
