چکیده
A water-soluble doubly N-confused hexaphyrin (N(2)CH) having two octa-arginine peptide arms displays an enhanced near-infrared (NIR) emission around 1050 nm in the presence of Zn(2+) in aqueous solution.

Confusion of Möbius aromaticity: disruption of annulenic pathway in singly N-confused [28]hexaphyrin and its mono-Pd(II) complex.
Singly N-confused [26] and [28]hexaphyrins (4, 5) with planar and twisted structures, respectively, were prepared via the acid catalyzed [3 + 3] condensation of N-confused and regular tripyrrane precursors. Hückel aromaticity is observed for [26]hexaphyrin, while the [28]hexaphyrin and its mono-Pd(II) complex exhibit "nonaromaticity" in spite of their Möbius-type structures, judging from the sp...
متن کاملQuinoline based fluorescent chemosensor for Zn in water
A highly sensitive fluorescent sensor, 8-(2-glucaminoacetylamino)quinoline, for Zn in water is synthesized by integrating a water-soluble glucose group with the 8-aminoquinoline fluorophore via a glycyl spacer. The sensor exhibits a highly selective fluorescence enhancement response to Zn over other metal ions. X-ray analysis shows that the deprotonation of NH in the sensor will occur upon bind...
متن کاملDetermination of Strontium Ion in Depilatory Powder, Toothpaste, and Raticide Samples using a Novel and Highly Sensitive Potentiometric Sensor Coupled with a Central Composite Design
The strontium ion, in water-soluble forms, is one of the major pollutant in drinking water. Therefore, a simple, rapid, selective, and sensitive potentiometric carbon paste electrode was developed to measure strontium ion in real samples with complex matrices. To prepare the potentiometric sensor, a synthetic ligand ((E)-4-(((2-amino-4-chlorophenyl)imino)methyl)-5-(hydroxymethyl)-2-methyl pyrid...
متن کاملRatiometric and absolute water-soluble fluorescent tripodal zinc sensor and its application in killing human lung cancer cells.
A new "naked-eye" and ratiometric fluorescent zinc sensor (TAQ) of carboxamidoquinoline with 2-chloro-N-(quinol-8-yl)-acetamide as a receptor was designed and synthesized. The sensor shows good water solubility and high selectivity for sensing; about a 15-fold increase in fluorescence quantum yield and a 100 nm red-shift of fluorescence emission upon binding Zn²⁺ in aqueous HEPES buffer solutio...
متن کاملVoltammetric Determination of Copper Ion in Water Samples Using a Drop Casted Biopolymer
Poly-dopamine, inspired by biopolymers of mussels, is an adhesive catecholamine possessing low cytotoxicity and very good biocompatibility. In the present study, poly-dopamine nanoparticles (PDNP), as a biopolymer, were synthesized and characterized using FTIR spectroscopy, scanning electron microscopy and electrochemical methods. The drop casted PDNPs at the surface of carbon paste electrode (...
