Abstract:
This study includs the synthesis of some new Amic acid and Imides,starting from the esters [S1] of Terephthalic acid which then converted toits hydrazide [S2] then to amic acid derivatives [S3-S7] and finally withimides [S8-S12]. Preparing of ester [S1] by usual esterification ofterephthalic acid with absolute ethanol in acidic medium, then hasconverted to its hydrazide [S2] by reacting it with hydrazine hydrate. Theamic acid derivatives [S3-S7] have been synthesized by the reaction ofhydrazide [S2] with anhydrides (2,3-dimethyl malic anhydride, 3-nitrophthalic anhydride, hexahydro phthalic an

Introduction: The synthesis of Schiff base has huge importance to prepare a lot of heterocyclic compounds, Oxazepines can be prepared by reaction of imine compounds with anhydrides to obtain seven-membered heterocyclic compound. Materials and Methods: A series of 1, 3-oxazepine derivatives were prepared, firstly preparation of the imines (S1-S2) from reaction of 2-chlorobenzaldehyde with each of p-toluidine and 4, 4’-Methylenedianiline and using glacial acetic acid as a catalyst. The second step involves the reaction of prepared Schiff bases (S1-S2) with both 3-nitrophthalic anhydride and Itac

Abstract:
Two series of ester imides from trimellitic anhydride as well as 6-nitrotrimellitic anhydride (4-carboxy-6-nitrophthalic anhydride) have been synthesized. Their thermotropic properties have been compared. Only one nitro compound, N-dodecyl-4-[(4’-decyloxybiphenyl-4-yl)oxycarbonyl]- 6-nitrophthalimide has shown liquid crystalline properties.

Abstract:
The reaction of 2-hydroxyethyl methacrylate with 3-nitrophthalic anhydride catalyzed with triethylamine results in the 3 : 1 mixture of two possible monoesters, the more populated one being that with the ester group in ortho position to the nitro group. The isomers were identified and quantified by 1H and 13C 1D and 2D techniques including APT, INEPT, superselective long-range (SSLR) INEPT, SSLR HHCR, COSY, NOESY, HETCOR and COLOC. Theoretical analysis was done on the model reaction of methanol with the anhydride using semiempirical AM1 quantum chemical calculations. The results indicate that

Abstract:
We fabricated organic light emitting devices (OLEDs) with thermally stable metal tetra-aminophthalocyanine (MT4APc, where M is Co, Cu, or Zn) dispersed in poly(bisphenol A-co-4-nitrophthalic anhydride-co-1,3-phenylenediamine) (polyetherimide, PEI) or 2,2-bis(3,4-dicarboxy-phenyl) hexafluoroisopropane dianhydride-2,4,5,6-trimethyl-1,4-phenylene-diamine (6FDA-4MPDA) polyimide (PI) as a hole transporting layer (HTL). The relative efficiency of the MT4APc as a HTL was found to be in the order CuT4APc &gt; CoT4APc ≈ TPD &gt; ZnT4APc. It was found that the 6FDA-4MPDA PI as a matrix of HTL exhibited

Abstract:
Heterocycles are an important class of organic compounds because of their applications in medicines and industrial fields. Therefore our study included preparation of these compound such as oxazepine and quinazoline rings, which were prepared through two steps: The first step included the reaction of the Schiff bases derived from sulfamethaxazole (1-4) with each of phthalic anhydride and 3- nitrophthalic anhydride for the preparation of oxazepines (5-12) .While the second step included the preparation of quinazoline compounds (13-16) from the reaction of Schiff bases (1-4) with anthranilic aci
