Synthesis and Structural Characterization of Trinuclear Cu2+, Zn2+ and Zn2+-Eu3+ Complexes Based on 2,3-Dihydroxybenzene-1,4-dicarbaldehyde, 1,3-bis(Aminooxy)propane with 3-Ethoxysalicylaldehyde
A novel bis(salamo)-type multipledentate chelating ligand H4L and its three Cu2+, Zn2+ and Zn2+-Eu3+ complexes have been designed and synthesized and characterized by elemental analyses, IR, UV-visible spectra and 1H NMR spectroscopy. The bis(salamo)-type compound H4L shows that the complexation between H4L and metal ions can affords 1:3 complex [M3(L)]2+ or [M12M2(L)]3+. The most likely structures of the Cu2+, Zn2+ and Zn2+-Eu3+ complexes have been suggested.

Five bisbenzoylthiourea compounds have been synthesized from benzoyl isothiocyanate and different diamines in CH2Cl2 medium under solid-liquid phase transfer catalysis conditions. Structures of these compounds have been characterized by elemental analyses as well as IR and 1H NMR spectroscopy. These compounds were tested for their antibacterial and antifungal activities. The results indicated most of the compounds have good antimicrobial activities, especially in against agriculture disease fungal.

A novel bifunctional-group salamo-like multi-purpose dye probe based on ESIPT and RAHB effect: Distinction of cyanide and hydrazine through optical signal differential protocol
solvent dependence may be caused by the ICT effect in the molecule. The probe p-TNS could be prepared into test strips for the detection of cyanide and hydrazine. In addition, the probe molecule can also be used to detect trace amounts of cyanide in agricultural products, and respond to gaseous hydrazine by direct contact, indicating that the probe p-TNS has good practical application prospects. Therefore
A more flexible salamo-based colorimetric and proportional chemical sensor with fast, highly sensitive and recyclable detection of cyanide and application in test paper
luminescence. The sensor DNTS can detect cyanide with high sensitivity through proportional fluorescence (398/468 nm), and its detection limit is about 0.128 μM. In addition, the successful used of the Cu2+ and CN− coordination mechanism making the sensor repeatable. In short, the sensor DNTS will be a promising device for detecting cyanide based on the successful development of teststrips.
