摘要

A compound represented by general formula (1). (In the formula, X is SiR₂, GeR₂, SnR₂, CR₂, SO₂, or POR'. The abovementioned R is a C1-10 alkyl group. The abovementioned R' is a C1-10 alkyl group, hydroxyl group, or phenyl group. R¹¹, R¹², R¹³, R¹⁴, R¹⁵, R¹⁶, and R¹⁷ each independently are a hydrogen atom, a halogen atom, a C1-10 alkyl group, a C1-10 alkoxy group, a C1-10 hydroxyalkyl group, a hydroxyl group, a carboxy group, an amino group, or an amide group. R¹² and R¹³, and R¹⁶ and R¹⁷, may connect to each other to form a ring. R¹⁸ is a group represented by formula (2). n¹¹ is an integer of 1-4. n¹² and n¹³ are integers of 1-3.)
