NOVELTY - Anthracene derivative containing thiophene is new.    USE - As light emitting material useful in organic light emitting device (claimed), e.g. organic solar cell, organic photoconductor and organic transistor. Also useful as light emitting dopant in combination with a host and light emitting host in combination with a dopant.    ADVANTAGE - The anthracene derivative containing thiophene is stable and efficient organic material for the organic light emitting device. The anthracene derivative containing thiophene has greatly increased light emission efficiency (quantum efficiency).    DETAILED DESCRIPTION - Anthracene derivative containing thiophene of formula (I) is new.
