氨丙基改性的不同比表面积和粒径的二氧化硅与4-（3，4-二氰基苯氧基）苯甲酰氯反应。这些苯甲酰氨基苯氧基二甲腈改性的硅胶与4-（4-叔丁基苯氧基）-1，2-苯二甲腈在锌（II）盐存在下的反应产生共价键合的酞菁锌（II）络合物，其负载量在1.8 × 10−5和1.7 × 10− 6 mol g−1二氧化硅之间。紫外/维斯反射光谱表明，表面酞菁以单体状态存在。在二氧化硅和酞菁之间的酰胺键处的断裂导致相应的单羧酸酞菁衍生物。
Silica of different surface area and grain size modified by aminopropyl groups reacted with 4-(3,4-dicyanophenoxy)benzoic acid chloride. The reaction of these benzamidophenoxydicarbonitrile modified silica gels with 4-(4-tert-butyl-phenoxy)-1,2-benzenedicarbonitrile in the presence of a zinc(II) salt results in covalently bonded phthalocyanine zinc(II) complexes with a loading between 1.8 × 10−5 and 1.7 × 10−6mol g−1 silica. UV/vis reflectance spectra show that the phthalocyanines on the surface exist in a monomeric state. Cleavage at the amide bond between the silica and the phthalocyanine led to the corresponding monocarboxylic acid phthalocyanine derivative.
