碩士 === 國立中正大學 === 化學研究所 === 86 === The main focuses of this thesis are to study the patterned surfaces of self-assembled monolayers and to characterize nano- sized metal materialsby scanning probe microscopy.In the first part, we have prepared the patterned self assembled monolayersby a microprinting technique.Two different kinds of monolayers, hydrophobicand hydrophilic alkanethiols , are grown on a gold surface. The imagesobtained by lateral force microscopy show the two distinguish regions and indicate that the differences are caused from the different forces between tip and monolayers. Furthermore, we have deposited CdSe nanocrystals capped with hydrophobic ligands onto the monolayers. The selective deposition of CdSenanocrystals onto hydrophobic monolayers has been revealed by atomic force microscopy (AFM). In the second part, AFM has been used to obtain the size and shape information of gold nano-rod and palladium nanoparticles.The results from The results from AFM agree with AFM agree with those obtained from transmission electron microscopy(TEM).
