Abstract

An organic compound represented by the following general formula is provided.

In the above formula (1), R₁₁ to R₁₅ each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, an aralkyl group, an acyl group, or a halogen atom provided that at least one of R₁₁, R₁₃, and R₁₅ represents the alkoxy group or the aryloxy group; and R₁₁ to R₁₅ may form a ring structure therebetween, R₅ and R₆ each independently represent an alkyl group, an aryl group, or an aralkyl group. In addition, R₂₁ to R₂₄ each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, an aralkyl group, an acyl group, or a halogen atom and may form a ring structure therebetween. The above groups except the acyl group may be substituted when necessary.
