Pentaammineruthenium(II/III) imidazole and imidazolate complexes of 2-carboxylatoimidazole and 2-imidazolecarboxaldehydeorgano‐ruthenium compoundsThe Ru(II) title complexes are prepared by reduction of ((NH 3 ) 5 RuCl) 2 + over Zn/Hg and reaction of the resulting ((NH 3 ) 5 Ru(H 2 O))...
The ZIF code: ZIF-90 materials were successfully synthesized in an optimized water-based system. The particle size, ranging from micro- to nanoscales, could be controlled by different amounts of polyvinylpyrrolidone (PVP), Zn/imidazole-2-carboxaldehyde ratio and alcohol (see figure).关键词:green...
3.5.2Zif-90 ZIF-90 is formed by Zinc ions and imidazole-2-carboxaldehyde (2-ICA). The ATP-responsive ZIF-90/Cas9nanoparticles(Fig. 7d) possessed loading efficiency above 90%[66]. The competitive coordination between Zinc ions and ATP provided a switch to control the release of payload. Aft...
Methotrexate (MTX), an anticancer drug as folic acid analogue was loaded into ZIF-90 through Schiff base reaction between amino group in MTX and aldehyde group of imidazole-2-carboxaldehyde ligand with drug loading amount about 250 mg/g. As a pH-sensitive biomaterial, chitosan (CS) was ...
A crack-free sub-nanometer composite structure for the study of ion transfer was constructed by in situ growth of ZIF-90 [Zn(ICA)2, ICA=Imidazole-2-carboxaldehyde] on the tip of a glass nanopipette. The potential-driven ion transfer through the sub-nanometer channels in ZIF-90 is ...

Different mole percentage of 2-methylimidazole and 2-imidazolecarboxaldehyde were mixed together to form ZIF-8-90 X%. We found that DMF had good effect on controlling the particle size but reducing the productivity ratio. The ZIF-8-90 X% NPs had different physical properties, such as surface ...

The new strategy is based on a controlled single‐crystal to single‐crystal linker exchange of 2‐methylimidazole in ZIF‐8 membrane grains with 2‐imidazolecarboxaldehyde (ZIF‐90 linker), thereby enlarging the effective aperture size of ZIF‐8. The linker‐exchanged ZIF‐8 membranes showed a ...
