BENZOTHIADIAZOLE DERIVATIVE, LIQUID CRYSTAL COMPOSITION, WAVELENGTH-CONVERTING ELEMENT, ELECTROLUMINESCENT ELEMENT, ELECTRIC CHARGE TRANSPORTATION MATERIAL AND PHOTOELECTRIC TRANSFER ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a new fluorescent benzothiadiazole derivative exhibiting high dichroism and solubility and useful for various elements such as display elements, e.g. liquid crystal elements or electroluminescent elements, wavelength- converting elements or photoelectric transfer elements, a liquid crystal composition using the derivative and various elements.;SOLUTION: The benzothiadiazole is represented by the general formula (I) (A¹ and A² are each independently phenyl group, an alkoxyphenyl group or the like). The liquid crystal composition is obtained by using the benzothiadiazole derivative. The liquid crystal display element, the wavelength- converting element, the electroluminescent element, the electric charge transportation material and the photoelectric transfer element are also provided.;COPYRIGHT: (C)2003,JPO
