Embodiment 1

[0018] The synthesis of the iron complexes with terpyridine derivatives as ligands of the present invention comprises the following steps:

[0019] 1. The synthesis steps of ligand 6,6''-(8-quinoline)-2,2':6',2''-terpyridine are as follows: 8-quinolineboronic acid (2.0mmol, 342mg), 6 ,6''-dibromo-2,2': 6',2''-terpyridine (1.0mmol, 390mg), tetraphenylphosphine palladium (0.05mmol, 57.8mg) and sodium carbonate (10.0mmol, 1.06g ) was dissolved in 20ml of a mixed solvent consisting of isopropanol and water with a volume ratio of 10:1, heated to reflux for 24h, cooled, and the solvent was removed by rotary evaporation, and the obtained solid was washed with water and methanol respectively to obtain the ligand 6,6' '-(8-quinoline)-2,2':6',2''-terpyridine, yield 94%, its chemical structural formula is as follows:

Abstract

The invention discloses an iron complex taking a terpyridyl derivative as a ligand, and a synthesis method and an application of the iron complex. The synthesis method of the iron complex taking the terpyridyl derivative as the ligand comprises the steps of dissolving the ligand, 6,6''-(8-quinoline)-2,2':6',2''-terpyridyl in ethanol, then adding ferrous perchlorate, stirring an obtained mixture atthe room temperature for 2h, after a reaction is finished, filtering off an undissolved substance, performing rotary evaporation to remove a solvent, washing with ethanol to form a solid, and obtaining the iron complex taking the terpyridyl derivative as the ligand after drying. The synthesis method has the advantages of simple technology, high productivity, mild reaction conditions, simple product purification treatment method and the like. The synthesized iron complex taking the terpyridyl derivative as the ligand has good catalytic activity for photocatalysis carbon dioxide reduction undernormal temperature and pressure conditions in an atmosphere, a TON (turnover number) can reach 500, and the iron complex has good industrial application prospects.

Description

technical field [0001] The invention relates to an iron complex, in particular to an iron complex with a terpyridine derivative as a ligand, a synthesis method and application thereof. Background technique [0002] The carbon dioxide emitted by humans in the process of production and life, in addition to being partially absorbed by plants, will also be emitted into the atmosphere in large quantities, becoming the main greenhouse gas that causes global environmental problems, and is also the main cause of the "greenhouse effect". However, carbon dioxide is also an important carbon resource, and its conversion and fixation are not only beneficial to alleviate the greenhouse effect, but also to obtain organic fuels or basic chemical raw materials. Therefore, the catalytic reduction of carbon dioxide to synthesize organic chemicals has great significance for environmental protection and energy utilization. The most promising application in the research of catalytic reduction of...
