2，9，16，23-四烷氧基酞菁钴(Ⅱ)的合成及光谱性质研究

Synthesis and study on spectral properties of the 2,9,16,23-tetraalkoxyphthalocyanine cobalt(Ⅱ)

用4-辛氧基邻苯二腈、4-十二烷氧基邻苯二腈和4-硝基邻苯二腈分别与氯化钴在熔融状态下合成了2,9,16,23-四-辛氧基钴酞菁和2,9,16,23-四-十二氧基钴酞菁以及无取代钴酞菁,对产物进行IR、UV-vis光谱测定和表征,并对比3种化合物谱学性质,可以得出:对于长链碳原子来说,随着碳原子数的增加,烷氧基取代酞菁产生的红移程度逐渐变小。

The preparation of （C8 H17O）4PcCo（ Ⅱ ）, （C,2 H250）4PcCo（ Ⅱ ） and PcCo（ Ⅱ ） （all the alkoxy groups in 2,9, 16,23 position） from 4-octanoxy-o-dicyanobenzens, 4-（ twelve alkoxy）-o- dicyanobenzens and 4-（nitro）-o-dicyano- benzens respective reacted with COCl2· 6H2O, uera and ammonium molybdate in molten state. IR spectra and UV-Vis electronic absorption spectra of the complexes were measured and studied. Compared to for the long chain alkoxy substitude phthalocyanine cobalt （ Ⅱ ）, The result showed the degree of redshift of 2,9,16,23-tetraalkoxyphthalocyanine cobalt （ Ⅱ ） will reduce with the increasing of the carbon chain.
