Assembly of dysprosium(iii) salts with versatile hydrazone H3L affords a variety molecular magnetic compounds from mononuclear, dinuclear, grid-like tetranuclear to linear 1D chain.

In the title compound, C(14)H(10)BrN(3)O(4)·CH(4)O, the dihedral angle between the two benzene rings in the hydrazone mol-ecule is 5.8 (3)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. An O-H⋯O hydrogen bond occurs between the hydrazone mol-ecule and the methanol solvent mol-ecule. In the crystal, the components are linked by inter-molecular N-H⋯O hydrogen bonds, for...

The asymmetric unit of the title compound, C(15)H(13)N(3)O(7)·2H(2)O, consists of a hydrazone mol-ecule and two solvent water mol-ecules. The mol-ecule adopts an E configuration with respect to the C=N bond. It is relatively planar, with a dihedral angle between the two benzene rings of 2.6 (1)°. There are intra-molecular O-H⋯N and O-H⋯O hydrogen bonds in the hydrazone mol-ecule. In the crystal...

A simple and efficient method has been developed for the synthesis of various 2-quinoxalinone-3-hydrazone derivatives using microwave irradiation technique. The series of 2-quinoxalinone-3-hydrazone derivatives synthesized, were structurally confirmed by analytical and spectral data and evaluated for their antimicrobial activities. The results showed that this skeletal framework exhibited marke...

A series of indole-based aryl(aroyl)hydrazone analogs of antiplatelet indole-3-carboxaldehyde phenylhydrazone were synthesized by the Schiff base formation reaction and their antiplatelet activity was assessed using human platelet rich plasma. The platelet concentrate was obtained using a two-step centrifugation protocol and ADP, arachidonic acid and collagen were used as inducers of platelet a...

A peptide-guided prodrug incorporating a tumor-specific peptide, doxorubicin, and a pH-sensitive hydrazone bridge was developed for targeted ablation of cancer cells with minimal side cytotoxicity.

Using a hydrazone exchange methodology, resin beads were functionalised with [2]rotaxanes at up to 80% efficiency—higher than using other dynamic or irreversible synthetic approaches form self-assembled structures on solid supports.

A norbornene-derived hydrazone polymer was developed for high selectivity, and to be used as an effective colorimetric fluorescent chemosensor of Al3+ in aqueous solutions.

A fluorescent hydroxyl- and hydrazone-based covalent organic framework (TFPB–DHTH COF) was synthesized as an “OFF–ON” sensor for cysteine l-histidine.
