Abstract: A compound is provided and is represented by the following formula (1): R1a, R1b, R1c, R1d, and R1e each independently represents a hydrogen atom or a monovalent substituent other than OH with a proviso that at least one substituent has a positive ?p value in Hammett equation and substituents may be coupled to each other to form a ring; R1f, R1g, R1h, R1i, and R1j each independently represents a hydrogen atom or a monovalent substituent other than OH with a proviso that substituents may be coupled to each other to form a ring; and R1k, R1m, R1n, and R1p each independently represents a hydrogen atom or a monovalent substituent with a proviso that substituents may be coupled to each other to form a ring.

Abstract: A compound represented by the following Formula (1): wherein, Het1 represents a bivalent five- or six-membered aromatic heterocyclic residue and may further be substituted; Xa to Xd each independently represent a heteroatom and may further be substituted; Ya to Yf each independently represent a heteroatom or a carbon atom and may further be substituted; the ring bound to Het1 may have a double bond at any position
