The invention provides a transition metal complex of formula (3) below:
wherein R1, R2, R3, R4, R5, R6, R7 and R8 are the same or different and each independently represents a hydrogen atom, a halogen atom or a substituted or unsubstituted alkyl group having 1 to 10 carbon atom(s); R5 represents a hydrogen atom, a fluorine atom or a substituted or unsubstituted alkyl group having 1 to 10 carbon atom(s); X1 represents a hydrogen atom, a halogen atom or a substituted or unsubstituted alkyl group having 1 to 10 carbon atom(s); L represents a balancing counter ion or neutral ligand similar to X1 that is bonding or coordinating to metal M; and q represents an integer of 0 or 1, and
G20 represents any one of G21 to G 26 below:
where A1 represent an element of Group 15 of the periodic table, wherein A1 in G23 represents an anion of an element of Group 15 of the periodic table, and A1 in G21 represents a nitrogen atom;
R9, R14, R12, R13, R19, R20, R10, R11, R15, R16, R17, R18, R19, R20, R31 and R22 each independently represents,
a hydrogen atom; or
a substituted or unsubstituted alkyl groups having 1 to 10 carbon atom(s), and
the line linking M and R20 represents that M is coordinated or linked to an element of Group 15 or 16 of the periodic table or to a fluorine atom constituting R20.
本发明提供了下式(3)的过渡金属配合物:
其中 R1、R2、R3、R4、R5、R6、R7 和 R8 相同或不同,且各自独立地代表氢原子、卤素原子或具有 1 至 10 个碳原子的取代或未取代的烷基;R5 代表氢原子、氟原子或具有 1 至 10 个碳原子的取代或未取代的烷基;X1 代表氢原子、卤素原子或具有 1 至 10 个碳原子的取代或未取代的烷基; L 代表与 X1 类似的平衡配位离子或中性配位体,与金属 M 结合或配位;以及 q 代表 0 或 1 的整数,且
G20 代表下文 G21 至 G 26 中的任一个:
其中 A1 代表元素周期表中第 15 族元素,G23 中的 A1 代表元素周期表中第 15 族元素的阴离子,G21 中的 A1 代表氮原子;
R9、R14、R12、R13、R19、R20、R10、R11、R15、R16、R17、R18、R19、R20、R31 和 R22 各自独立地代表、
一个氢原子;或
具有 1 至 10 个碳原子的取代或未取代的烷基,以及
连接 M 和 R20 的直线代表 M 与元素周期表中的第 15 或 16 族元素或构成 R20 的氟原子配位或连接。
