[0032] A preparation method of an organometallic rhodium compound, comprising the following steps:
[0033] Step 1. Dissolve 2,4-pentanedione, 3,4-dimethoxybenzaldehyde and diboron trioxide together in pure DMF solution, and react at 70-90°C for 5-7 hours under the protection of nitrogen, preferably Under the protection of nitrogen, react at 80°C for 6 hours, add hydrochloric acid, and leave to precipitate to obtain (1E,3Z,6E)-1,7-bis(3,4-dimethoxyphenyl)-3-hydroxyl-1,3, 6-heptatrien-5-one, the structural formula is as follows:
[0034]
[0035] Step 2, the p-dimethylaminobenzaldehyde and the (1E,3Z,6E)-1,7-bis(3,4-dimethoxyphenyl)-3-hydroxyl-1,3,6- Heptatrien-5-one is dissolved in pure toluene, mixed with pure acetic acid, reacted at 100-200°C for 5-10h, preferably at 150°C for 8h, and (1E,6E)-1,7-di (3,4-dimethoxyphenyl)-4-(p-methylaminophenylvinyl)-1,6-heptadiene-2,5-dione, the structural formula is as follows:

Embodiment 1
[0044] 1. Product preparation
[0045] Dissolve 0.095g of 2,4-pentanedione, 0.12g of 3,4-dimethoxybenzaldehyde and 1mmol of boron trioxide in 10ml of DMF solution, react at 80°C for 6 hours under the protection of nitrogen, and then add 8ml of 0.5M Hydrochloric acid, standing and precipitating to obtain (1E, 3Z, 6E)-1,7-bis(3,4-dimethoxyphenyl)-3-hydroxyl-1,3,6-heptatrien-5-one; 20 mg of p-dimethylaminobenzaldehyde and 40 mg of (1E,3Z,6E)-1,7-bis(3,4-dimethoxyphenyl)-3-hydroxy-1,3,6-heptanetri En-5-one was dissolved in 10ml of toluene, added 0.5mg of acetic acid, reacted at 150oC for 8h, and (1E,6E)-1,7-bis(3,4-dimethoxyphenyl)-4-(p- (1E,6E)-1,7-bis(3,4-dimethoxyphenyl)- 4-(p-methylaminophenylvinyl)-1,6-heptadiene-2,5-dione and 40 mg dichloro(pentamethylcyclopentadienyl) rhodium (III) dimer were dissolved in 8ml of dichloromethane, heated, stirred and refluxed for 16 hours. After the reaction was completed, the solution was evaporated to leave 3ml of liquid, and 15ml of eth...
