| Abstract
| - Benzyl phenyl sulfide (BPS, C6H5CH2−S−C6H5) is readily converted on silver to benzenethiolate byirradiation with visible light. By using this knowledge and invoking the fact that BPS is easily replacedby carboxylic acids, we have demonstrated by surface-enhanced Raman scattering that patterned binarymonolayers can be prepared on silver using the self-assembled monolayers of BPS as a lithographic template.Although the example shown in this work, that is, binary monolayers composed of benzenethiolate and4-cyanobenzoate, is rather preliminary and quite limited in scope, its application prospects are thoughtto be very good. Because surface-induced photoreaction of aromatic sulfides including BPS can occur evenon gold induced by UV radiation, the present method is expected to be applicable to forming patterns andstructures with a wide variety of materials on silver and gold with features that range from nanometersto micrometers in size.
