Aryl ethers coupled pyridoxal as supramolecular gelator for selective sensing of F?

Aryl ethers coupled pyridoxal Schiff base 1 has been synthesized and its gelation properties have been examined. The gelator 1 forms colorless gels from various solvents such as DMSO, DMF, DMSO/H2O and DMF/H2O. The gel matrix obtained from DMSO shows ribbon-like fibrous morphology and has been utilized for efficient ‘naked eye’ detection of fluoride ion through a reversible gel-sol transition, which is associated with color change from almost colorless to yellow. In DMSO, the Schiff base 1 has also been observed to sense F?ion more efficiently over the basic ions AcO?and CN?. Though few examples of anion sensing in solution with pyridoxal-based Schiff bases are known, anion recognition utilizing pyridoxal-based gelators is unexplored in the literature.

Novel coumarin-based containing denrons selective fluorescent chemosesor for sequential recognition of Cu2+ and PPi

In this study, we have successfully synthesized a novel coumarin-based dendrons derivative CD and its chemical structure was characterized by 1H NMR, 13C NMR and ESI-HR-MS. The sensor CD showed an obvious “on-off” fluorescence quenching response toward Cu2+ with a maximum quenching efficiency of 99.8%. The CD-Cu2+ complex showed an “off-on” fluorescence enhancement response toward PPi over many competitive anions. The detection limit of the sensor CD was 0.29 × 10?6 M to Cu2+ and 2.39 × 10?9 M to PPi. In addition, the sensor CD showed a 1:1 binding stoichiometry to Cu2+ and the sensor CD-Cu2+ showed a 2:1 binding stoichiometry to PPi in CH3CN/HEPES buffer medium (9:1 v/v, pH = 7.2). The stable pH range of sensor CD to Cu2+ and CD-Cu2+ to PPi was from 3 to 8.

Poly(aryl ether) Dendrons with Monopyrrolotetrathiafulvalene Unit-Based Organogels exhibiting Gel-Induced Enhanced Emission (GIEE)

A series of poly(aryl ether) dendrons with a monopyrrolo-tetrathiafulvalene unit linked through an acyl hydrazone linkage were designed and synthesized as low molecular mass organogelators (LMOGs). Two of the dendrons could gelate the aromatic solvents an

Zinc aluminum ion identification fluorescence probe as well as preparation method and application thereof

The invention provides a zinc aluminum ion identification fluorescent probe and a preparation method and application thereof, wherein a Schiff base structure and three benzyl groups are contained in the fluorescent probe molecule. The zinc-aluminum ion fluorescent probe provided by the invention has a double mechanism. The method has the characteristics of double response, high sensitivity, high specificity, no influence on other metal ions, easy cell uptake, low cytotoxicity and the like. The probe is applied to peripheral blood of prostate cancer patients, can quantitatively detect the zinc content in serum, and provides valuable information for diagnosis of suspected prostate cancer patients. The prostate cancer serum PSA is detected and combined, the diagnosis accuracy of prostate cancer can be effectively improved, the puncture diagnosis requirement of patients in the grayscale range of the serum PSA is avoided, and further excessive diagnosis and excessive treatment can be avoided.

Visual detection of fluoride ions

Dendrimer-hydrazides are coupled to polycyclic aromatic hydrocarbons for use in the visual detection of the presence of low levels of fluoride in a sample. The dendrimers can have a phenyl core, a first generation of aralkyl ethers, and an optional second generation of aralkyl ethers. The compounds form gels with solvents. In the presence of fluoride ion, the gels undergo color changes and/or gel to liquid phase change.

Supramolecular design for two-component hydrogels with intrinsic emission in the visible region

We report, for the first time, an in situ formation of two-component hydrogels from pyridine derivatives of poly(aryl ether) dendrons and tartaric acid. The two-component system (dendron + acid) undergoes J-type aggregation, leading to fibrillar type self-assembly in THF-water mixture along with blue (470 nm) and green (500 nm) intrinsic emissions.

Glucose-cored poly(aryl ether) dendron based low molecular weight gels: PH controlled morphology and hybrid hydrogel formation

We designed poly(aryl ether) dendron based transparent hydrogels containing glucose moiety, which undergoes in situ transition from nanofibers to spherical aggregates, upon pH variation. The process is reversible and the assembled structures have been characterized by DLS and SEM. More importantly, efficient dispersion of graphene oxide results in lower CGC (0.08 wt%) value and higher mechanical strength, compared to the native gel.

Low molecular weight fluorescent organogel for fluoride ion detection

The design, synthesis, and the photophysical properties of a Low Molecular Weight Gel (LMWG) based on AB3 and AB2 type poly(aryl ether) dendrons with an anthracene chromophore attached through an acylhydrazone linkage are described. The gel is utilized for an efficient 'naked eye' detection of fluoride ions (as low as 0.1 equiv with respect to the gelator concentration), through a reversible gel-sol transition, which is associated with a color change from deep yellow to bright red.

Decorating the lanthanide terminus of self-assembled heterodinuclear lanthanum(iii)/gallium(iii) helicates
