A novel phthalazine based highly selective chromogenic and fluorogenic chemosensor for Co2+ in semi-aqueous medium: application in cancer cell imaging

A new phthalazine based chemosensor 3 was developed for the highly selective and sensitive detection of Co2+ in the mixed solvent system, CH3CN- H2O ( 1 : 1, v/ v). In the presence of Co2+, the colour of the solution 3 changed from yellow to green; the absorption maxima of 3 was red- shifted from 383 nm to 435 nm, and the fluorescence of 3 at 550 nm was significantly enhanced. The sensor 3 showed a detection limit down to 25 nM by forming a complex species with Co2+ in 1 : 1 stoichiometry. Furthermore, by means of confocal laser scanning microscopy experiments, it has demonstrated that it can be used as a fluorescent probe for monitoring Co2+ in living cells.

Structural control: can [2 x 2] silver grids be formed from 4,5-disubstituted 3,6-di(2-pyridyl) pyridazines?

The reaction of ligands based on 3,6-di(2-pyridyl)pyridazine with symmetrical carbocyclic rings fused to the pyridazine ring; 7,10-di(2-pyridyl)-8,9-diazafluoranthene (L-1), 1,4-di(2-pyridyl)-6,7,8,9-tetrahydro-5H-cyclo-hepta[d]pyridazine (L-2), 1,4-di(2-pyridyl)-5,6,7,8-tetrahydro-phthalazine (L-3), 1,4-di(2-pyridyl)-6,7-dihydro-5H-cyclo-penta[d]pyridazine (L-4) with silver salts gave a series of complexes (1-7). Characterisation of these using single crystal X-ray structure determination clearly showed that the steric bulk of the carbocycle affects the degree to which pyridine groups remain co-planar with pyridizine, and hence their ability to chelate. The more hindered ligands L-1-L-3 form a mixture of bischelating and tetrabridging, while the least hindered (L-4) was able to chelate exclusively. In the case of L-4, the nature of the anion and solvent were also able to affect the outcome of the reaction, with tetrafluoroborate giving the first example of a 4,5-substituted 3,6-di(2-pyridyl) pyridazine ring forming a [2 x 2]-grid.

An 850 nm pure near-infrared emitting iridium complex for solution-processed organic light-emitting diodes

High-performance pure near-infrared organic light-emitting materials and devices with full emission over 700 nm are still rare, though urgently needed. Iridium(iii) complexes have been proven to be an important class of NIR emitters. Herein, we report a new NIR homoleptic Ir(iii) complex, tris[1,4-di(5-n-octylthiophen-2-yl)benzo[g]phthalazine] iridium(iii) (Ir(dotbpa)(3)), with full emission beyond 700 nm with an iridium mass content as low as 10 wt%. Thanks to the introduction of flexiblen-octyl groups,Ir(dotbpa)(3)shows greatly improved solubility and excellent solution-processability in comparison with its counterpartIr(dtbpa)(3). By utilizing a multifunctional host, solution-processed NIR-OLEDs were fabricated with a simple structure of only three organic layers and they demonstrated a pure NIR emission starting from 725 nm and a peak at 850 nm with the maximum external quantum efficiency of 0.17%, which makes them the first example of pure NIR-OLEDs based on Ir(iii) emitters.

Inhibition of water adsorption into polar solid-phase microextraction materials with ultrathin polydimethylsiloxane coating for thermal desorption-gas chromatography analysis

Solid-phase microextraction (SPME) coupled with thermal desorption-gas chromatography (TD-GC) has become a powerful analysis tool for volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) in water samples. However, water adsorption into polar microextraction phase is usually unavoidable during the extraction process, and the burst of large amounts of water vapour during thermal desorption will cause serious problems to GC separation and detectors. Pawliszyn’s group had demonstrated that the tens of micron-thick, defect-free polydimethylsiloxane (PDMS) coating could act as a perfect barrier for water adsorption and offer much better compatibility in complex matrices. However, the PDMS overcoat largely decreased the uptake rate of polar analytes into the inner sorbent. In order to quantify the effect of PDMS coating thickness on water adsorption amount and the extraction kinetics, ultrathin PDMS layer was used to coat the polar extraction phase with polyimide (PI) as a model in this work. It was surprising to find that the PDMS coating with the thickness less than one micron can decrease the water adsorption by 96%, while the extraction efficiency for polar analytes (phenolic compounds and nitroaromatic explosives) was decreased by less than 20% at the extraction time of 30 min. Moreover, the kinetic data showed that the thinner the PDMS coating was, the less the uptake rate of polar analytes into PI extraction phase decreased. Finally, polar poly (phthalazine ether sulfone ketone) (PPESK) extraction phase was also coated with ultrathin PDMS coating to verify the universality of the strategy. Generally, the water adsorption problem in polar SPME was overcome to a great extent, and the extraction efficiency of polar analytes was mainly preserved with this ultrathin PDMS coating, which could broaden the application of SPME in the environmental field.

CuO nanoparticles as a reusable catalyst for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives under solvent-free conditions

Nanostructured CuO was successfully utilized for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives via one-pot multicomponent reaction among phthalhydrazide, malononitrile and aromatic aldehydes under solvent-free conditions. Utilization of non-toxic and inexpensive catalyst, improved yields in short reaction times, wide substrate scope and easy purification of products are the important features of the developed protocol. The CuO nanocatalyst presents good reusability over five catalytic cycles.

Moreover, the Co/Al2O3 is recyclable up to 7 consecutive runs by simple filtration.

1,3-Diylideneisoindolines: Synthesis, Structure, Redox, and Optical Properties

Diiminoisoindoline (DII) is a crucial reagent for the synthesis of phthalocyanine as well as related macrocycles and chelates such as hemiporphyrazine and bis(iminopyridyl)isoindoline. In this report, we present the synthesis and characterization of four 1,3-diylideneisoindolines prepared via the reaction of several organic CH acids and DII. These orange or red compounds exhibit intense pi-pi* transitions in the UV visible region. The redox properties and electronic structures of all new compounds were investigated using cyclic voltammetry and density functional theory (DFT). The observed electrochemistry and UV-visible transitions are in good agreement with the DFT and time-dependent DFT calculations, which indicate that the HOMO is largely centered at the O=C-C-C=O fragments, and the lowest unoccupied molecular orbital is more extended onto the isoindoline unit.

A facile electrochemical method for the synthesis of new sulfonamide derivatives of potential biological significance

The electrochemical synthesis of some new sulfonamide derivatives was carried out via the electrochemical oxidation of 2,3-dihydrophthalazine-1,4-dione (1) in the presence of arylsulfinic acids (2a and 2b) as nucleophiles. The results show that, the electrogenerated phthalazine-1,4-dione (1ox) participates in a Michael type addition reaction with 2a or 2b and via an EC mechanism to produce the corresponding sulfonamide derivatives. This method provides a one-pot procedure for the synthesis of new sulfonamide derivatives of potential biological significance in good yields without using toxic reagents at a carbon electrode in an environmentally friendly manner.
