Abstract:
Aromatic aldehydes such as Benzaldehyde (BA) and Salicylaldehyde (SA) are widely found in
industrial wastewater. The selective chemosensors for aromatic aldehydes in aqueous solution were rarely
reported. We have designed the florescent probes based on spherical silica nanoparticles (SiNPs) with
modification of hydrazine moiety as a binding site. This hydrazine group would react with an aldehyde
compound to produce the hydrazone compounds through a Schiff-based reaction. However, the limitation of
the general organic probes in aqueous solution is poor solubility and weak fluorescence. To improve the well-
dispersed manner of the fluorescent probe, SiNPs which were prepared from Stober process were utilized.
Hydrazine naphthalimide functionalized spherical silica nanoparticles (SiNPs-Naph-NH) were synthesized
via grafting 3-aminopropy1 triethoxysilane (APTES) to the surface of SiNPs (diameter of 44.1 + 4.6 nm) to
produce amine functionalized SiNPs (SiNPs-NH). The modification of naphthalic anhydride and hydrazine
on SiNPs-NH were then respectively introduced as the fluorophore and aldehyde active sites to afford the
sensing materials of SiNPs-Naph-NH. Taking on broad sensing approaches, the turn-off fluorescence
response of SiNPs-Naph-NH was changed to "turn-on" fluorescence upon reacting with aromatic aldebydes
especially BA and SA in acetate buffer pH 5.0. Among aldehyde compounds of formaldehyde (FA), short-
chain aldebydes C3-C5, long-chain aldehydes C6-C7 and 3-bydroxy benzaldehyde (3-HBA), the observation
of the fluorescent enhancement at 530 nm in the case of BA and SA suggested a premising selectivity for
aromatic aldehyde compounds. These results revealed that SiNPs-Naph-NH performed an effective
fluorescence sensor in aqueous media with high specificity for BA and SA
