PLATINUM COMPLEX

摘要

A platinum complex represented by the following formula (1) or (2): wherein the ring A, ring B, ring C, ring D and ring G independently represent an aromatic ring optionally having a substituent or an aromatic heteroring optionally having a substituent, X represents an oxygen atom or sulfur atom, R<1> and R<2 >independently represent a hydrogen atom or a substituent, the ring E and the ring F independently represent a nitrogen-containing aromatic heteroring optionally having a substituent, with the proviso that R<1 >and the ring B and also R<2> and the ring B each may together form a condensed ring and that the ring E and the ring F may together form a condensed ring. The platinum complex is useful as a material for a luminescent element of an organic EL element or the like, and can provide an element being extremely good in thermal stability, luminous characteristics and luminous efficiency.
