【 摘 要 】

Ionic palladium(II) complex, [(Me₄en)Pd(L)]₂(ClO₄)₄ (Me4en = N,N,N�?,N�?-tetramethylethylenediamine; L = bis- (4-(4-pyridylcarboxyl)phenyl)methane), allows to form a monodisperse submicrosphere without any template or additive. Surface-perchlorates on the submicrosphere have been exchanged by anionic pH indicators such as thymol blue, bromothymol blue, and bromocresol green. The ionic and amphiphilic properties of the palladium(II) complex appear to be primarily associated with the formation and easy surface-anion exchange of submicrosphere. The surface-anion exchange through the electrostatic interaction is a very good tool for the surface-modification. The color of the pH indicator-exchanged submicrospheres is very sensitive to pH and Hg²⁺ cation, and thus they are promising to submicrospherical indicators.
