技術說明

(中文) 本發明之碳烯 (carbene) 三牙基配體，此配位基與中心金屬螯合時會形成六員環與五員環，相較先前錯合物的配位模式更趨於理想幾何結構。金屬與配體間透過形成更強的共價鍵，達到最佳化的結晶場能，在保有剛性強、穩定性高的同時，提高發光效率。再者，不僅是搭配其他三配位發光團的銥金屬錯合物抑或是與鉑金屬進行配位，本發明之錯合物之合成均為簡易、純化方便且產率高，有利於商業化量產。 (英文) The primary objective of the present invention is to provide a series of blue-emitting, Ir(III) and/or Pt(II) based metal complexes bearing carbene chelates with fused five-six-membered metallacycles, which are in sharp contrast to the traditional designs of chelates that form the alternative, fused five-five metallacycles. The larger bite angles are expected to afford an ideal coordination geometry. Then, stronger metal–carbene interactions is expected to offer a higher ligand field strength and emission efficiency. On the other hand, the complexes of this invention is easily synthesized, convenient to purify, and has a high synthetic yield; therefore, they are suitable for possible commercialization.
