ABSTRACT
A novel ferrocene-functionalized silver cluster (FcAgCs) has been designed and synthesized with the assistant of ultrasound treatment and fully characterized by single crystal spectroscopy, IR, UV-Vis, XRD, TGA, NMR, CV and elemental analyses. Ultrasound synthesis method facilitates and accelerates synthesis of this amazing structure and plays a vital role in the synthesis of this special cluster. Single-crystal X-ray analysis reveal that the cluster can be described as a cationic [(dppf)2Ag4(CCtBu)2(CH3OH)2]2+ (dppfâ¯=â¯1,1'-bis(diphenylphosphino)ferrocene) species consisted of four rhombic silver atom and two isolated BF4- counter anions. Thermal stability greater than 200⯰C and solution CV results show that the title cluster is sufficiently stable and suitable for the fabricating of FcAgCs/ITO thin-films and exploring as electrochemical responding materials. Based on its properties, we use it to prepare thin-films on ITO substrate by spin coating method. Verification of synthesis, thickness, uniformity and stability of the fabricated FcAgCs/ITO thin-films were characterized and confirmed by UV, XRD, SEM and the scotch tape adhesion peel test. Moreover, we use this FcAgCs/ITO thin-film electrode as thin-film electrochemical detector which shows sensitive and quick response in the detection of H2O2.
