Cyclic tetradentate metal platinum complex phosphorescent material and use thereof

A cyclic tetradentate metal platinum complex phosphorescent material having a general structure represented by formula (I),

• where, X is CR1R2 or NR3;
• X1 is selected from NR4, O or S;
• each of R1-R4 is independently selected from hydrogen, halogen, substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C1-C30 cycloalkyl, substituted or unsubstituted C1-C30 heterocycloalkyl, substituted or unsubstituted C1-C30 cycloalkyl, substituted or unsubstituted C6-C60 aryl, substituted or unsubstituted C6-C18 arylamine, substituted or unsubstituted C6-C18 heterocycloamine, and combination thereof;
• Y1-Y16 are each independently selected from C or N;
• Ra, Rb, Rc, Rd and Re each independently represent mono-to maximum substitution, or no substitution, and are each independently selected from hydrogen, halogen, substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C1-C30 cycloalkyl, substituted or unsubstituted C1-C30 heterocycloalkyl, substituted or unsubstituted C1-C30 cycloalkyl, substituted or unsubstituted C6-C60 aryl, substituted or unsubstituted C6-C60 heteroaryl, and combination thereof;
• at least one hydrogen in R1-R4, Ra, Rb, Rc, Rd and Re is substitutable by deuterium;
• the substituent in the “substituted or unsubstituted” radical is selected from one or more of deuterium, halogen, methyl, ethyl, propyl, isopropyl, butyl, t-butyl, pentyl, phenyl;
• in case of substituted by multiple substituents, the multiple substituents are the same or different from each other;
• when containing a heteroatom, the heteroatom is selected from O or N;
• the two or more adjacent substituents of R1-R4, Ra, Rb, Rc, Rd and Re are independently or optionally linkable to form a fused ring.
