(57) [Summary] (Modified) [Purpose] Obtaining a giant polycyclic compound capable of obtaining a giant polycyclic rare earth complex with high dynamic stability (low dissociation rate constant) . [Structure] A large polycyclic compound represented by the formula [I]. [Z: trivalent or tetravalent atom, R: hydrogen, hydroxyl group, amino group or hydrocarbon group or none, A, B and C: a divalent group of A, B and C At least one contains a triplet energy donor group (selected from phenanthrylone, mantracene, bipyridine, isoquinoline) having a triplet energy higher than the emission level of the complexed rare earth ion. ] |
