Patent ID: 8652363

Claim:
A boron compound represented by the following general formula (I): wherein R 1 to R 16 may be the same or different from each other, and each represent a hydrogen atom, a halogen atom, a nitro group, a cyano group, an amino group, an alkyl group having 1 to 20 carbon atoms optionally having substituents, an aryl group having 6 to 20 carbon atoms optionally having substituents, an alkoxy group having 1 to 20 carbon atoms optionally having substituents, an aryloxy group having 6 to 20 carbon atoms optionally having substituents, an arylalkyl group having 7 to 20 carbon atoms optionally having substituents, a cycloalkyl group having 5 to 12 carbon atoms optionally having substituents, an alkylthio group having 1 to 20 carbon atoms optionally having substituents, an arylthio group having 6 to 20 carbon atoms optionally having substituents, an alkylamino group having 1 to 20 carbon atoms optionally having substituents, or an arylamino group having 6 to 20 carbon atoms optionally having substituents, wherein the adjacent two groups of the groups represented by R 1 to R 16 may link to form a 5-membered ring or a 6-membered ring together with the carbon atom to which the respective two groups are binding.
