<p>A vanadium di-nuclear complex represented by the following general formula (1-3):
wherein A 1 , A 2 , A 3 and A 4 each independently represent an oxygen atom, or NR 11 , and B 1 , B 2 , B 3 and B 4 each independently represent -O- or NR 12 -;
R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 each independently represent a C1-30 hydrocarbon group optionally substituted by a C1-50 alkoxy, nitro, cyano or halogen group; or a C1-40 hydrocarbonoxy group optionally substituted by a C1-50 alkoxy, nitro, cyano or halogen group; R 9 and R 10 each independently represent a C 1-20 alkylene group optionally substituted by a C1-50 alkoxy, nitro, cyano or halogen group; or R 9 and R 10 represent a C6-60 arylene group optionally substituted by a C1-50 alkyl, C7-50 aralkyl, C1-50 alkoxy, nitro, cyano or halogen group; or R 9 and R 10 represent -O-, -S--SO 2 - or NR 13 -; and when R 9 and R 10 exist in a plural number respectively, they may be the same or different; m and n each independently represent an integer of 1 to 7; R 11 , R 12 and R 13 each independently represent a hydrogen atom or a C1-30 hydrocarbon group optionally substituted by a C1-50 alkoxy, nitro, cyano or halogen group; when R 11 , R 12 and R 13 exist in a plural number respectively, they may be the same or different; when both of A 1 and A 2 and/or both of A 3 and A 4 are together NR 11 respectively, two R 11 s may combine to form a C1-20 divalent hydrocarbon group optionally substituted by a C1-30 hydrocarbon, C1-40 hydrocarbonxy, nitro, cyano or halogen group which connects A 1 and A 2 and/or A 3 and A 4 to each other; and when both of B 1 and B 2 and/or both of B 3 and B 4 are together -NR 12 - respectively, two R 12 s may combine to form a C1-20 divalent hydrocarbon group optionally substituted by a C1-30 hydrocarbon, C1-40 hydrocarbonxy, nitro, cyano or halogen group which connects B 1 and B 2 and/or B 3 and B 4 to each other.</p> |
