“…Fig. 1 shows a schematic representation of the preparation of the present 1D nano-composites, which can be divided into the following steps: (i) the functionalization of MWNTs as-received with P4VP to produce MWNTP4VP hybrids [25], (ii) the preparation of benzyl chloride functionalized silica nanoparticles of nano-SiO 2 BenCl hybrids [26], and (iii) the construction of MWNTP4VP@nano-SiO 2 BenCl nano-cores, as well as MWNTP4VP@nano-SiO 2 BenV and MWNTP4VP@nano-SiO 2 BenV/PMA nano-composites.…”

“…As shown in Fig. 1, the MWNTs as-received were modified with a highly active benzyl bromide intermediate (MWNTBenBr) via the diazonium coupling process [25,27], followed by an addition reaction with P4VP to produce the MWNTP4VP hybrids. The nano-SiO 2 BenCl hybrids were obtained by a sol-gel process [26].…”

Organic-inorganic nano-materials have attracted growing attention due to their potential applications for optoelectronic devices, sensors, and heterogeneous catalysts. We reported here on the preparation of polynary nanocomposites composed of poly(4-vinylpyridine) (P4VP) functionalized multi-walled carbon nanotubes (MWNTP4VP), silica nanoparticles (nano-SiO 2), viologens, and/or phosphomolybdic acid (PMA), in which the MWNTP4VP, nano-SiO 2 , and viologens were covalently connected while PMA was electrostatically adsorbed. Thermogravimetric analysis revealed that the nanocomposites were composed of about 40-45% MWNTs, 40-45% nanoSiO 2 , as well as 10-15% organic species and others. The preparation processes and compositions of the nanocomposites were characterized using Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. Field emission transmission electron microscopic images revealed that the nano-SiO 2 BenV particles were strongly attached

“…where n is the number of exponential terms, B i is the contribution of each exponential term at t = 0, and  i is the associated decay times [21]. It can be seen that, for the C element, besides the main peak at the binding energy of 284.6 eV corresponding to the C atoms from the C-C and C=C bonds, there existed another small one at about 288 eV corresponding to the C atoms from the C-N and C=N bonds [32,33]. Further, compared with the spectrum of the nano-SiO 2 NH 2 hybrids ( Fig.…”

Luminescent pyrene-functionalized nano-SiO 2 (nano-SiO 2 Pyr) hybrids were synthesized and characterized using thermogravimetry, infrared, UV-vis absorption and, X-ray photoelectron spectroscopy, as well as field emission transmission electron microscopy (FETEM). The organic substituents immobilized on the nano-SiO 2 Pyr hybrids accounted for approximately 10% of the total weight. Polyethylene glycol 200 (PEG200) was found to be the most suitable solvent to suspend the nano-SiO 2 Pyr hybrids compared to other commonly used organic solvents. FETEM images indicated an average SiO 2 nanoparticle diameter of approximately 12 nm and a 1-to 2-nm thick organic species functionalization layer. Several emission peaks were recorded at wavelengths of 380-580 nm and were designated as emissions arising from either the monomer or excimer of the pyrene substituents. Excimer formation was concentration and solvent polarity dependent, with higher concentrations and a stronger solvent polarity benefiting excimer formation. Further, nano-SiO 2 Pyr hybrids were doped in poly(methyl methacrylate) (PMMA) thin films; fluorescence spectra indicated that the excimer could be formed almost exclusively from neighboring nano-SiO 2 Pyr hybrids. Time-resolved fluorescence decays revealed that the emission lifetimes of nano-SiO 2 Pyr monomers
