  • Platinum complex, nitrogen-containing bidentate chelate, and apparatus for providing visible emission or near-infrared emission
    Patent number: 11414447
    Abstract: Provided is a platinum complex having a structure represented by formula (I): wherein A1 to A3 each independently represent a 5-membered or 6-membered unsaturated ring, A3 is optionally formed between A1 and A2; X1, X2, and X3 each independently represent carbon or nitrogen; R1 represents hydrogen, substituted or unsubstituted C1-C6 alkyl, —CF2H, —CFH2, substituted or unsubstituted C6-C12 aryl or —CmF2m+1, m is an integer of 1 to 5; R2 and R3 each independently represent hydrogen, C1-C12 alkyl, substituted or unsubstituted C1-C6 alkoxyl, substituted or unsubstituted C6-C12 aryl, or —CnF2n+1, n is an integer of 0 to 3; p and q each independently represent an integer of 1 to 2; and when p or q is equal to 2, two R2's or R3's may join to form a C3-C8 aromatic or nitrogen-containing heteroaromatic ring.
