Abstract
The present invention relates to an organometal-complex luminescent material which has a structural formula (I), wherein A, B and C refer to substituted or unsubstituted C, N, O and S atoms independently; a dashed ring for linkage between A and B atoms refers to a substituted or unsubstituted conjugated ring structure; L1, L2, L3 and L4 are single bonds or double bonds independently, wherein L3 and L4 are part of the conjugated ring structure for linkage between A and B atoms; X, X1, Y and Y1 are C, N, O and S atoms independently; Ar1 and Ar2 are substituted or unsubstituted conjugated ring structures independently; M refers to Pt, W and Au atoms. An organometal complex in the luminescent material is high in fluorescence quantum efficiency and heat stability and low in quenching constant and can be used for manufacturing high-efficiency and low-efficiency roll-off red-light OLEDs.
