Cyclic compound, its metal complex and modified metal complex

摘要

A compound represented by formula (1):;wherein Y1 to Y4 each independently represent any one of the following groups:;
in which Rα represents a hydrogen atom or a monovalent hydrocarbon group; P1 to P4 each independently represents a group of atoms necessary for forming a heterocyclic ring together with each Y1 to Y4 and the two carbon atoms adjacent to Y1 to Y4, respectively; P5 and P6 each independently represents a group of atoms necessary for forming a cyclic skeleton together with 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 represents a connecting group or a direct binding; and Z1 and Z2 each independently represent any one of the following groups;
—NRβ2, —ORβ, —SRβ, —PRβ2
in which Rβ represents a hydrogen atom or a monovalent hydrocarbon group, and when plural Rβs are present, these plural Rβs may be the same or different from each other.
