Abstract In this paper, Salen‐Ni basis polyphosphazene microsphere (Salen‐PZN‐Ni), boric acid (BA), and 3‐aminopropyltriethoxysilane (KH‐550) were used as raw materials to prepare a new flame retardant Salen‐PZN‐Ni@BA@KH‐550 by surface modification. The thermal properties of epoxy resin (EP) composites studied. introduction refined the stability EP composites, well amount carbon residue at 800°...

A new dealkylation reaction between organophosphate esters and Salen aluminum bromide compounds has been used to prepare three new aluminum salen compounds salen((t)Bu)AlOP(O)Ph2 (1) (salen = N,N'-ethylenebis(3,5-di-tert-butylsalicylideneimine)), [(MeOH)Alsalen((t)Bu)[OMePO2(O)]Alsalen((t)Bu)[OMePO2(O)]Alsalen((t)Bu)]Br (2), and [salpen((t)Bu)AlO]2[(BuO)2PO]2 (3) (salpen = N,N'-propylenebis(3,5...

A series of salen-type zirconium complexes of the general formula LZrCl2 (L = N,N 0-ethylenebis(salicylideneiminate), 3a; N, N 0-ethylenebis(3,5-di-tert-butylsalicylideneiminate), 3b; N,N 0-ethylenebis(5-methoxysalicylideneiminate), 3c; N,N 0-ethylenebis(5chlorosalicylideneiminate), 3d; N,N 0-ethylenebis(5-nitrosalicylideneiminate), 3e; N,N 0-o-phenylenebis(salicylideneiminate), 4a; N,N 0-o-phe...

Homochiral metal-organic frameworks with fine-tuned pore sizes/walls and large surface areas are promising porous materials for enantioseparation considering the traditional zeolite molecular sieves have no chirality. Using enantiopure pyridyl-functionalized salen [(N-(4-Pyridylmethyl)-L-leucine·HBr)] as a starting material, we have prepared a noninterpenetrated three-dimensional homochiral met...

We previously investigated the utility of μ-oxo N,N'- bis(salicylidene)ethylenediamine iron (Fe(Salen)) nanoparticles as a new anti-cancer agent for magnet-guided delivery with anti-cancer activity. Fe(Salen) nanoparticles should rapidly heat up in an alternating magnetic field (AMF), and we hypothesized that these single-drug nanoparticles would be effective for combined hyperthermia-chemother...

Two hydroxo-bridged complexes, {[Mn(III)(3-CH(3)O)salen](2)[Cr(III)(salen)(OH)(2)]}ClO(4)·6H(2)O (1) and {[Mn(III)(5-CH(3))salen](2)(OH)}ClO(4)·3H(2)O (2) [salen = N,N'-ethylenebis(salicylideneiminato) dianion], have been synthesized by the hydrolysis of the corresponding Mn(III)(Schiff-Bases) derivatives and [Cr(salen)(H(2)O)(2)]Cl precursors. X-Ray structure characterization reveals the discr...

The five-coordinate compound, Salen((t)Bu)Al(Ac), prepared in situ from Salen((t)Bu)AlBr and NH4Ac, forms Lewis acid-base adducts in aqueous solution with the G-type nerve agents, Sarin and Soman, and the VX hydrolysis product, ethylmethylphosphonate (EMPA). The resulting compounds, [Salen((t)Bu)Al(NA)](+)[Ac] (-) (with NA = Sarin, Soman, and EMPA) are sufficiently stable to be identified by ES...

The new [Co(Salen)(PBu3)2]ClO4, [Co(Salen)(PBu3)2]BF4, [Co(Salpn)(PBu3)2]ClO4 and [Co(Salen)(PMe2Ph)2]ClO4 ( where salen = bis(salisylaldehyde)ethylenediimine)) complexes were synthesiszed and chracterized by IR, UV-Vis, 1H NMR spectroscopy and elemental analysis. The IR and 1H NMR spectra cofirmed that the synthesised complexes contain Schiff base ligand, phosphane and conter ion and the eleme...

In an effort to obtain synthetic analogues of water-oxidizing complex (WOC) of photosystem II (PS II) of plant photosynthesis, a Schiff base manganese and a cobalt complex, employing Niten, a SALEN type ligand, have been prepared. Cyclic and square wave voltammetric measurements have been performed to assess their redox characteristics. Both complexes undergo several reduction processes in cath...

We have observed that the superoxide anion reacts with VO(salen), but not with VO(saldpt), where H2(salen) and H2(saldpt) are Schiff base ligands derived from salicylaldehyde and ethylenediamine or dipropylenetriamine, respectively. Based on the electrochemical, ESR, and UV spectroscopic studies of the reaction mixture, it was concluded that the superox­ ide anion reacts with VO(salen) to oxidi...
