This paper reports the syntheses of acetylene-terminated smallmolecule
cores. Also reported are successful attempts at “click”
coupling the core molecules with azide-terminated oligonucleotides to
construct stable small-molecule DNA hybrids (SMDH). Once these
click-based small-molecule DNA hybrids are formed, melting studies
will be done that study how the geometry of SMDH...
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...
Several phosphonate-functionalized molecular
squares have been successfully synthesized,
and the fabrication of multilayer films
on both conductive and semiconducting
platforms has been demonstrated. These
films were grown using the well-documented
zirconium phosphonate multilayer method.
The layer-by-layer growth rate is uniform.
Experiments suggest, however, that the
molecular squares adopt a semi-collapsed...
