Particular interest exist in the formation of hybrid organic-inorganic material layers on semiconductor and insulator surfaces in which it is possible to control the function and properties by the nature and type of the incorporated metal ions [1]. A palladium (II) metal-organic complex with terpyridine ligand is synthesized in solution and deposited on a pyridine terminated quartz surface. The deposition process through organometallic complex can be one of the ways to functionalize surfaces with various organic molecules like dyes. This can be possible by further modifying the terpyridine ligand with different kind of organic molecules of interest. AFM, FT-IR spectroscopy and contact angle measurements are performed to characterize both the linker as well as organometallic functionalized quartz surfaces. The UV absorption spectrum yields two maxima at 353 nm and 370 nm of the organometallic functionalized quartz surface.
