Abstract:
In order to comparatively studythe properties of theαandβalkoxy-substituted phthalocyanines, these two series of tetra-substituted phthalocyanines were synthesized from corresponding 3-alkoxyphthalonitrile and 4-alkoxyphthalonitrile with metal salts. The effect of temperature on the synthesis of phthalonitrilewas studied, the results indicated that theα-substituted derivativeswere formed more easily than correspoindingβderivatives. Two condensation methods of phthalonitriles were investigated comparatively. An attemptwas made to correlate the different substituted positions with the spectral performance ofPc. The results shown thatthe differentsubstituted has little effecton the maximumabsorption wavelength. In the contrary, the solubility can be improved largely by the introduction of the bulk high brached substituents. The spectra data also demonstrated that the maximum absorbance of phthalocyanine with the substituted group located in theαposition had large red-shift than that in theβposition. The results showed that the alloxy-substituents in theαposition had larger pertubance on theπconjucted systemof phthalocyanine than inβposition. The relationship between their structure and other properties including solubility and thermal gravity losses were also presented and discussed.

摘要:
利用3-烷氧取代邻苯二腈和4-烷氧取代邻苯二腈与相应的金属盐反应制备了两大系列(α-和β-)四烷氧取代酞菁.讨论了温度对中间体烷氧取代邻苯二腈合成的影响,探讨了酞菁的两种环合方法,并对β-烷氧酞菁的环合历程进行了初步的考察.研究了不同取代位置和酞菁的最大吸收波长之间的关系,结果表明, α-取代烷氧取代酞菁导致λmax红移值较大,而相应β位取代情况下红移值较小,说明给电子基团在α位对酞菁骨架的π共轭结构微扰作用比β位大.同时研究了溶解度及热失重与酞菁结构的关系.
