this paper presents the development and experimental utilization of a synchronized off-harmonic laser system designed as a probe for ultra-intense laser±plasma interaction experiments. the system exhibits a novel seed-generation design,allowing for a variable pulse duration spanning over more than three orders of magnitude, from 3.45 picoseconds to 10 nanoseconds. this makes it suitable for various plasma diagnostics and visualization techniques. In a side-view configuration, the laser was employed for interferometry and streaked shadowgraphy of a laser-induced plasma while successfully suppressing the self-emission background of the laser±plasma interaction, resulting in a signal-to-self-emission ratio of 110 for this setup. these properties enable the probe to yield valuable insights into the plasma dynamics and interactions at the PHELIX facility and to be deployed at various laser facilities due to its easy-to-implement design.

Using symmetrical rigid organic ligand 4,4'-dipyridy (4,4'-bipy), two new Anderson-based supramolecular compounds, namely, [H2(4,4'-bipy)]3·(teMo6O24)·(H2Mo6O19) (1) and {Cu2[H(4,4'-bipy)] 2(H2O)6(teMo6O24)}·4H2O (2), were synthesized in one-pot under hydrothermal conditions. the compounds 1 and 2 have been tested by IR spectra, elemental analyses and single-crystal X-ray diffraction. Compound 1 contains one discrete Anderson anion, one Lindqvist anion and three 4,4'-bipy organic ligands. the anions and 4,4'-bipy alternate with each other by hydrogen bonding, building a supramolecular 1D chain. Adjacent 1D chains are interlinked through hydrogen bonding interactions to further connect a supramolecular 2D layer. Compounds containing both Anderson and Lindqvist polyanions are not common in the crystal structure of POMs. Compound 2 contains one Anderson anion and two metal-organic subunits {Cu2[H(4,4'-bipy)]2 (H2O)6}6+ as modifiers. the Anderson anions and {Cu2 [H(4,4'-bipy)]2 (H2O)6}6+ subunits are organized into alternating through hydrogen bonding interactions to construct a supramolecular 1D chain. Additionally, the electrochemical properties of compounds 1 and 2 as well as photocatalytic properties are investigated. Results show that compounds 1 and 2 have photocatalytic activity, which can photocatalyze the degradation of organic dyes MB and AF. Also, compounds 1 and 2 have good electrochemical properties for amperometric detection of NO2- and Cr(?). Furthermore, Compound 2 can be used as materials of supercapacitor. © 2024, Department of Chemistry, Northeast Normal University. All rights reserved.
