Abstract
A compound represented by formula (1): in which Rα represents a hydrogen atom or a monovalent hydrocarbon group; P1 to P4 each independently represent a group of atoms necessary for forming a heterocyclic ring together with each of Y1 to Y4 and the two carbon atoms adjacent to each of Y1 to Y4, respectively; P5 and P6 each independently represent a group of atoms necessary for forming a cyclic skeleton together with the carbon atom to which Z1 bonds or Z2 bonds and the two carbon atoms adjacent to the carbon atom to which Z1 bonds or Z2 bonds; P1 and P2, P2 and P6, P6 and P4, P4 and P3, P3 and P5, and P5 and P1 may further combine with each other to form a ring; Q1 and Q2 each independently represent a connecting group or a direct binding; and Z1 and Z2 each independently represent any one of the following groups;
