Based on a series of asym. bis-Schiff base H₂Lⁿ (n = 1-4) ligands with different electronic and steric effects, a series of [Mn(Lⁿ)Cl] complexes 1-4 are obtained and shown to be effective catalysts in ring-opening copolymerization of epoxides and dianhydrides. Through the structure design, the input of electron-withdrawing bromine substituent para to the phenoxide group of the complexes is considerately beneficial to the improved activities. Moreover, steric and electronic effects of the suitable MeO substituent at the ortho orientation on the phenoxide group may both play a role in the formation of alternating ring-opening copolymers under the identical reaction conditions. In three cocatalysts tested, n-Bu₄NBr is pos. to monomer conversion and chain growth of polymer.

Many loaded-catalysts are applied to the Mannich reaction, but they have disadvantages such as low yield, unstability of loaded rate and asking for long time. 404 Organic support loaded phosphotungstic acid was synthesized by the reaction of 404 organic support and phosphotungstic acid in CC14. The effects of different reaction conditions on the yields were investigated. The condensation reaction of aromatic aldehydes and 1-phenyl-3-methyl-4-benzoyl-pyrazolone was catalyzed by 404 organic support loaded phosphotungstic acid. Simultaneously the products were determined by IR, ¹HNMR and elemental anal. The catalyst was provided with stable cubic crystal spatial structure and good dispersion. This protocol has advantages of stability of loaded rate, short time, mild condition, high yield, high selectivity, simple work-up, environmental friendly procedure and the catalyst can be reused.

Li, Tianrong published the artcileA rhodamine 6G derivative as “turn-on” fluorescent probe for Cu²⁺. Spectroscopy, single crystal structure and DFT calculations, Application of 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, the publication is Polyhedron (2017), 154-159, database is CAplus.

In order to achieve an effective “turn-on” fluorescence detection of Cu²⁺, a rhodamine 6G-based sensor [1-phenyl-3-methyl-5-hydroxypyrazole-4-benzoyl(rhodamine 6G) hydrazone, 1] was prepared Fluorescence and UV-Vis absorption titration, detection limit, single crystal structure, binding mode, and quantum mech. calculation studies were also discussed in detail. Sensor 1 showed highly selectivity and sensitivity to Cu²⁺ among common cations (Na⁺, K⁺, Mg²⁺, Ca²⁺, Mn²⁺, Co²⁺, Ni²⁺, Zn²⁺, Cd²⁺, Cr³⁺, Fe³⁺ and Cu²⁺) in acetonitrile. Upon addition of Cu²⁺, a new absorption band at 523 nm, and a strong emission band centering at 557 nm appeared in 1 solution Relevant solution changed from colorless to purple, and an obvious orange fluorescence emission was given. A maximum fluorescence enhancement of 250 times at 557 nm could be made by addition of 6 equiv of Cu²⁺. The fluorescence detection limit was calculated to be 2.5 μM (0.20 ppm) for Cu²⁺, and 1:1 stoichiometry between Cu²⁺ and 1 was proved. In the single crystal of 1-Cu²⁺ complex, rhodamine moiety exhibited an open cycle form. We believe 1 can be a good candidate for the fluorescence detection of Cu²⁺.

The structural analyses reveal that complexes 1, 2 and 3, formed by H₂L with metal nitrate, have Zigzag chain, double-stranded chain and mononuclear structures, resp., and the ligands adopt three different coordination modes in these complexes. While, complex 4, formed by H₂L with Mn acetate, represents a 2-dimensional network structure with dinuclear units bridged by EtOH mols. The metal atom and counteranion have certain influences on the structures of resulting complexes. The fluorescent properties of 1 and 2 and the magnetism of 4 were studied.
