Formylation of metallocomplexes of tetra-meso-(para- and meta-methoxyphenyl)porphyrins
摘要:
The Vilsmeier formylation of metallocomplexes of isomeric meta- and para-methoxy-substituted tetraphenylporphyrines has was been studied. Formyl derivatives of meta-isomers were shown to form cyclization products not only in solutions, but also in the the solid state. The ability to undergo such transformations follows decreases in the trend following order: Co > Cu > Ni > Pd > Pt.

The invention relates to ÿ-substituted porphyrins, methods for their synthesis, and their use in the preparation of photoelectric materials. In particular, the invention relates to solid state photoelectric devices, including solar cells and photodetectors, incorporating these photoelectric materials, with improved photon-to-current conversion efficiencies.
zinc complexes of pyrrolo[1,2-a]quinoxalinoporphyrins in good yields. The newly synthesized porphyrins were characterized on the basis of spectral data. The preliminary photophysical studies of these pyrrolo- and indolo[1,2-a]quinoxalinoporphyrins demonstrate a significant red shift in their electronic absorption and emission spectra due to the extended π-conjugation in comparison to the corresponding

A divergent one-pot domino strategy for the synthesis of nickel(II) and copper(II) β-thiophene-fused 5,10,15,20-tetraarylporphyrins was developed through a thiol-Michael addition of thioglycolic/thiolactic acid to the corresponding 2-iminoporphyrins, formed in situ after the reaction of nickel(II) and copper(II) 2-formyl-5,10,15,20-tetraarylporphyrins with sterically hindered tert-butylamine in 1,2-dichloroethane
通过将巯基乙酸/硫代乳酸与相应的物质进行硫醇-迈克尔加成,开发了一种用于合成镍( II )和铜( II )β-噻吩稠合5,10,15,20-四芳基卟啉的发散式一锅多米诺策略。 2-亚氨基卟啉,镍( II )和铜( II )2-甲酰基-5,10,15,20-四芳基卟啉与空间位阻叔丁胺在1,2-二氯乙烷中在80℃下反应后原位形成。有趣的是,2-甲酰基卟啉与相对较小空间位阻的伯胺和巯基乙酸的反应提供了β-取代的卟啉噻唑烷酮和β-噻吩稠合卟啉的混合物。应用类似的一锅硫醇-迈克尔方案构建了一种新型游离碱噻吩并[2,3- b ]-内消旋-四(4-甲氧基苯基)卟啉,通过在 CHCl 3中使用乙酸锌进行锌插入 – MeOH混合物并以可观的分离收率得到锌( II )β-噻吩稠合的内消旋-四(4-甲氧基苯基)卟啉。在光物理评估中,与内消旋四芳基卟啉结构单元相比,这些新的卟啉表现出适度的红移电子吸收。

Treatment of nickel(II) and copper(II) complexes of 2(beta)-formyl-meso-tetraphenylporphyrins with strong acid results in intramolecular cyclization involving the carbonyl carbon and the ortho-phenyl position leading to naphthoporphyrin derivatives. However, when electron-releasing groups are present at the m-phenyl positions, a second cyclization occurs involving the 3(beta) position and the ortho position of the adjacent phenyl ring to give an additional fused ring.
