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...
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...
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...
