چکیده مقاله:

      A novel podand based anion receptor bearing benzimidazole motifs as recognition sites was designed and synthesized by reaction of 1,7-bis(2'-methylbenzoate)-1,4,7-trioxaheptane and phenylenediamine. The binding properties of anionic guest with this receptor were studied using UV-Vis and fluorescence spectroscopy. These studies revealed that this receptor exhibit selective recognition towards F- ionamong other anions such as HSO4-, ClO4-, Cl-, Br- and I- in methanol through intermolecular hydrogen bonding of guest and host. Also, we have focused our attention on the receptor-F- with theoretical computation based on DFT/B3LYP/6-31G(d).

Synthesis of Novel Bis-Benzimidazolyl Podands: A new Chemosensor for Cu2+

Some new compounds based on bis-benzimidazole moieties have been synthesized and characterized by IR and NMR spectroscopies. The ability of 3a in transition metal cation sensing such as Co2+, Ni2+, Zn2+, Mn2+, Fe2+ and Cu2+ have been investigated by Uv-vis and fluorescence spectroscopy in methanol solvent. The complexation constants and complex stoichiometry of Cu2+ have been determined. The ex...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

wuthering heights and the concept of marality/a sociological study of the novel

to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...

part a: application of n-(p-toluenesulfonyl) imidazole (tsim) and triphenylphosphine/carbon tetrachloride in several organic transformations part b: application of 8-bromocaffeine for synthesis of some novel 8-caffeinyl derivatives

بخش اول این پایان نامه به طور عمده بر توسعه کاربردهای جدید n-(پارا-تولوئن سولفونیل) ایمیدازول (tsim) و تری فنیل فسفین/ تتراکلرید کربن در تبدیل گروههای عاملی به یکدیگر استوار است. نظر به تنوع زیاد، دردسترس بودن، سمیت کمتر و نقل و انتقال آسان تر الکل ها نسبت به آلکیل هالیدها، تبدیل مستقیم گروه هیدروکسیل به گروه های عاملی دیگر مثل آزید، نیتریل و استر یکی از مهم ترین تبدیلات در سنتزهای آلی است. با ...
