Description:: The formation of organic layers on hydrogen-passivated silicon (HPS) surfaces via (UV) ultraviolet treatment was completed for three styrene derivatives with different conjugated lengths. The styrene molecules were synthesized and characterized using nuclear magnetic resonance (NMR) spectroscopy and gas chromatography-mass spectrometry (GC-MS). Layer formation on silicon was then accomplished through...

Description:: The formation of covalently grafted polymer brushes on silica (SiO2) nanoparticles was achieved by surface-initiated reversible additionfragmentation chain transfer (si-RAFT) polymerization. RAFT initiator was first attached onto the surface of silica nanoparticles and then examined by ultraviolet-visible spectroscopy (UV-vis) analysis. From the resulting RAFT initiator-modified SiO2 nanoparticles, polymer chains can...

Description:: This research illustrates the modification of an iodostyrene layer on a Si(111) surface using a Sonogashira reaction. This was accomplished by applying UV irradiation (254 nm) to a hydrogen-passivated silicon surface in a solution of iodostyrene in benzene, followed by a Sonogashira coupling between the iodine group from iodostyrene and...
