A series of Pt(II) complexes having the following formula are disclosed:
X1 and X2 independently are C or N, X1 can also locate at another position of the hexagonal ring, when X1 is N;
R1 is H, C1–C8 alkyl, or C1–C4 perfluoroalkyl, R2 is H, R1 and R2 together are C4–C8 alkylene, or R1 and R2 together are bridged carbocyclic C4–C12 alkylene, when X2 is C;
R1 is H, C1–C8 alkyl, or C1–C4 perfluoroalkyl, and R2 is omitted, when X2 is N;
R7 is H or methyl, and R8 is omitted, when X1 is N;
R7 is H or methyl, R8 is H or methyl, or R7 and R8 together are
when X1 is C.
揭示了具有以下公式的一系列Pt(II)络合物:X1和X2独立地是C或N,当X1为N时,X1也可以位于六角环的另一个位置;R1是H,C1-C8烷基或C1-C4全氟烷基,R2是H,R1和R2一起是C4-C8烷基,或者R1和R2一起是桥接的碳环C4-C12烷基,当X2为C时;R1是H,C1-C8烷基或C1-C4全氟烷基,而R2被省略,当X2为N时;R7是H或甲基,R8被省略,当X1为N时;R7是H或甲基,R8是H或甲基,或者R7和R8一起是当X1为C时。
