摘要

Au 30900 /Cit胶体纳米粒子与5,10,15,20-四(4′- n -甲基吡啶基)卟啉配合物与锌静电相互作用，形成了两种不同的组成不变的纳米共轭物，其紫外可见光谱与初始试剂不同。第一种更稳定的化合物的形成伴随着共轭试剂的Soret带和表面等离子体共振(SPR)带的强度降低和红移，它们保持了它们的光谱同一性。第二共轭物的形成伴随着Soret带强度的增加，而SPR带没有明显变化。有人认为，首先形成的是只有一个螯合的纳米缀合物，这降低了纳米颗粒进一步缀合的能力。

Conjugates of Zinc Tetramethylpyridylporphyrinate with Colloidal Gold Nanoparticles Stabilized with Citrate

Due to electrostatic interaction of Au 30900 /Cit colloidal nanoparticles with 5,10,15,20-tetrakis(4’-N-methylpyridyl) porphine complex with zinc two different nanoconjugates of constant composition are formed one after another, the UV-Vis spectra of which differ from those of initial reagents. The formation of the first, more stable, compound is accompanied by a decrease in intensity and a red shift of the Soret bands and surface plasmon resonance (SPR) band of the conjugated reagents, which retain their spectral identity. The formation of the second conjugate is accompanied by an increase in the intensity of the Soret band while the SPR band is not changed significantly. It has been suggested that the first to form is a nanoconjugate with only one tetracation, which reduces the ability of the nanoparticle to further conjugation.
