The phthalimide fused-ring system and the phenyl-ene ring in the title compound, C(15)H(11)NO(3), are inclined at an angle of 54.2 (1)°.

Abstract A sulfonic acid-functionalized trimethyl-substituted polyimide was synthesized by reacting 4,4?-(hexafluoroisopropylidene)diphthalic anhydride (6FDA) and 3,5-diamino-2,4,6-trimethylbenzenesulfonic acid (TrMSA). The properties of 6FDA-TrMSA were compared to the related 6FDA-derived analogues made from 2,4,6-trimethylbenzene-1,3-diamine (6FDA-TrMPD) 3,5-diamino-2,4,6-trimethylbenzene ben...

This paper proposes a new methodology in investigating the semantic and pragmatic properties of SFPs in Mandarin Chinese. A case study of the interaction and correlation between SFP-Ne and SpOAs--Shenzhi, Qishi, and Nanguai has been conducted. Two semantic features of [+unexpectedness] and [+intersubjectivity] have been summarized on SFP-Ne.

and Applied Analysis 3 open topic. For example, it is yet not clear whether the dual approach to (7) of [29] can be extended to the SFP. The original algorithm given in [15] involves the computation of the inverse A (assuming the existence of the inverse of A), and thus has not become popular. A seemingly more popular algorithm that solves the SFP is the CQ algorithm of Byrne [16, 21] which is ...

A global analysis of spin-flavour precession (SFP) solutions to the solar neutrino problem is given, taking into account the impact of the full set of latest solar neutrino data, including the recent SNO data and the 1496–day Super-Kamiokande data. These are characterized by three effective parameters: ∆m sol ≡ ∆m, the neutrino mixing angle θsol ≡ θ and the magnetic field parameter μB⊥. For the...

Shape from Polarization (SfP) estimates surface normals using photos captured at different polarizer rotations. Fundamentally, the SfP model assumes that light is reflected either diffusely or specularly. However, this model is not valid for many real-world surfaces exhibiting a mixture of diffuse and specular properties. To address this challenge, previous methods have used a sequential soluti...

We report here the development of a general strategy for site-specific labeling of proteins with small molecules by posttranslational modification enzyme, phosphopantetheinyl transferase Sfp. The target proteins are expressed as fusions to the peptide carrier protein (PCP) excised from nonribosomal peptide synthetase, and Sfp catalyzes the covalent modification of a specific serine residue on P...

Caprolactam-based ionic liquids show many advantages, such as the lower toxicity, lower cost, and a simple preparation process. In this work, caprolactam-based ionic liquids were prepared and adopted as catalysts for the transesterification of Jatropha oil with methanol. The results demonstrated that the SO3H-functional caprolactam-based ionic liquids have higher catalytic activity than those o...

The whole mol-ecule of the title compound, C17H10N4O5·2H2O, is generated by twofold rotation symmetry and it crystallized as a dihydrate. The planes of the phthalimide moieties and the urea unit are almost normal to one another, with a dihedral angle of 78.62 (9)°. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional framework structure. The cryst...

N-hydroxyethyl phthalimide (PE-I) was prepared by refluxing phthalic anhydride with ethanolamine. 3phthalimidoethyl substituted benzoic acids (PE-II) were prepared by refluxing N-hydroxyethyl phthalimide with substituted benzoic acids. The corresponding acid chlorides (PE-III) were condensed with benzilidine-4acetophenone derivatives to afford the 3-(phthalimidoethyl)-4-substituted cinnamoyl su...
