The Special Modifiers Containing N-Trimellitylimido-L-Amino Acids for the Surface Modification of Nano ZrO2

The most important difficulties about nanoparticles (NPs) in liquid media involve stabilizing them. So, it is necessary to modify the NPs surface by modifiers to generate an effective repulsive force between them. Dispersion of NPs will influence their ap

An effective and environmentally friendly method for surface modification of amorphous silica nanoparticles by biodegradable diacids derived from different amino acids

Commercially available silicon dioxide (SiO2) nanoparticles (NP)s were modified by chiral diacid coupling agents by ultrasonic irradiation. The acid groups can interact with the hydroxyl groups on the surface of SiO2 NPs. The interac

Synthesis and properties of optically active nanostructured polymers bearing amino acid moieties by direct polycondensation of 4,4′-thiobis(2- tert-butyl-5-methylphenol) with chiral diacids

Four derivatives of N-trimellitylimido-l-amino acid (4a-4d) were prepared by the reaction of trimellitic anhydride (1) with the l-amino acids (2a-2d) in acetic acid as diacid monomers and were used with the aim to obtain a new family of amino acid based p

Nanostructure formation in chiral poly(amide-imide)s based on dopamine moiety and N-trimellitylimido-L-amino acids in the main chain

Nanostructured poly(amide-imide) (PAI) materials have been produced by polymerizing a diamine monomer, 3,5-diamino-N-(3,4-dihydroxyphenethyl) benzamide, with four trimellitic anhydride-derived, imide ring-preformed chiral amino acid-based dicarboxylic aci

Design of one-pot green protocol for the synthesis of novel modified LDHs with diacids based on amino acids: morphology and thermal examinations

In this study, a simple, fast and environmentally friendly protocol has been proposed for the synthesis of layered double hydroxides (LDHs) and organomodified chiral LDHs under ultrasound irradiation as a green and fast tool for the first time. Novel chiral LDHs were synthesized in one step from the co-precipitation reaction of the Al(NO3)3·9H2O, Mg(NO3)2·6H2O and different bioactive N-trimellitylimido-l-amino acids in aqueous state. The obtained materials were studied by several methods such as Fourier transformed infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy techniques. The results of structural and morphological analyses showed the successful intercalation of chiral diacids within the interlayer of LDH clay. Thermal properties were investigated by thermogravimetry analysis. The results showed that there were four weight loss steps during the thermal decomposition. The amino acid containing N-trimellitylimido diacid created a chiral environment in the modified LDH that could be used in the chiral field.

Sonochemical preparation and characterization of modified CuO nanocrystalline with bioactive chiral diacids derived from different natural amino acids

To improve the dispersion ability of CuO nanoparticles (NPs), their surface was modified by chiral diacids (DAs) containing amino acids. The surface modification process was achieved using ultrasonic irradiation. DA could be absorbed on the surface of CuO

Efficient preparation of new nanostructured poly(amide-imide)s condensed from 3,5-diamino- N -(thiazole-2-yl)benzamide and various n -trimellitylimido-l- amino acids

In this study, new chiral poly(amide-imide)s (PAIs) were synthesized from polycondensation reaction of 3,5-diamino-N-(thiazole-2-yl)benzamide with various N-trimellitylimido-L-amino acids in a green medium consisting of molten tetra-n-butylammonium bromid

Nanoparticles dispersion in processing nanostructure chiral poly(amide-imide)S based on N-trimellitylimido-L-leucine/tio2 nanocomposites: Allocation and properties

Poly(amide-imide)s (PAI)s as engineering materials have received more attention owing to their high thermal and chemical stability. Therefore, organic/ inorganic nanocomposite (NC) of these materials has been widely studied in the last few decades. Here,

Synthesis and characterization of new optically active poly(amide-imide)s based on n-trimellitimido-l-amino acid and trimethylene units

Hydrolytically degradable amino acid containing polymers

A universal approach to incorporate amino acids into a polymeric backbone via hydrolytically labile bonds is reported. The amino acids were first converted into dicarboxylic acids by derivatization at their amino terminus with trimellitic anhydride and su
