- Abstract
- In this paper we show how to synthesize multi-functional silica nano particles and
modify thiol terminated hyper-branched silica nanoparticles, poly(amidoamine) with
thiol, but also detect with cadmium for the chemosensor. Multifunctional silica nano
particles were prepared by an acid-base catalyst method, pH controlled with
vinyltrimethoxysilane, 3-mercaptopropyltrimethoxysilane and (3-aminopropyl)
trimethoxysilane in an aqueous solution. The step-growth of hyper-branched
ploy(amidoamine) silica particles was synthesized by Michael addition with methyl
acrylate(MA) and the amidation of ethylenediamine(EDA). Finally, hyper-branched
silica nanoparticles, poly(amidoamine), was exchanged amine for thiol from methy
mercaptoacetate(MMA). 1st, 3rd, and 5th generations were exhibited synthesis
reaction by IR spectrum. TMPyP is a group of organic compounds, including the
porphine nucleus structure, that acts as quadridentate ligands to form chelate bonds
with a cadmium ion. As a result, the oxidation of multi-functional silica nano
particles and thiol-terminated hyper-branched silica particles were tagged TMPyP
(meso-tetrakis(N-methylpyridinium-4-yl)porphyrin) in H2
O. In addition, we
considered that thiol-terminated hyper-branched silica nano particles have more
chemosensing effect because of structural features. Depend on concentration of
TMPyP and generations of hyper-branched polymers, we acknowledged changed
intensity with detection of a cadmium ion by a solid UV spectrum.
