Summary: Mn(II) complexes, [Mn(L1)] 1 and [Mn(L2)] 2, based on o-phenylenediamine macrocyclic ligands, are reported as T1-MRI contrast agents. These complexes have a high spin state of Mn(II) (S = 5/2), as confirmed by EPR spectra. The complexes have an irreversible Mn(II)/Mn(III) redox potential at pH 7.28, which changes at acidic and alkaline pHs. The r(1)-relaxivity of the complexes is influenced by pH and the presence of other ions.

Summary: The spin-lattice relaxation time in silver-(II)-derived molecular systems with spin 1/2, namely [AgII(m-CTH)-(NO3)2] and [AgII(m-CTH)-(ClO4)2], has been studied using alternating-current susceptometry and ultralow-frequency Raman spectroscopy. The combination of both techniques reveals the occurrence of slow spin magnetic relaxation induced by spin-phonon interaction. The magnetic behavior of these silver-(II)-derived systems introduces a new cation in the scarce family of S = 1/2 systems with slow relaxation of magnetization.

Summary: This article describes nanogels based on a chitosan matrix stabilized by a Mn-t-CDTA bisamide derivative. These nanogels are proposed as an alternative to less stable paramagnetic nanogels obtained by electrostatic interactions. The novel nanogels have improved relaxivity values, high stability, good extravasation and accumulation, and high T-1 contrast in tumors. These properties make them promising MRI probes for in vitro and in vivo preclinical applications.

Summary: A new pyridine-based macrocyclic ligand with an acetate pendant arm (L1) was synthesized and its Mn(II) complex (MnL1) was studied for MRI contrast agent development. The X-ray structure confirmed the coordination geometry of MnL1, and potentiometry determined the stability constants of various metal complexes of L1. L1 exhibited higher stability and inertness compared to the parent macrocycle without the acetate pendant arm.

Summary: In this study, a new concept of pH-mediated magnetic sensors for chemical sensing was demonstrated. The strategy is based on the oxidation of paramagnetic Mn2+ ions to insoluble Mn(IV)O(OH)2 by dissolved oxygen under alkaline conditions, resulting in a significant decrease in water proton transverse relaxation rate (1/T2). By combining this reaction with enzymatic reactions that cause pH changes, pH-mediated chemical sensors based on magnetic relaxation principles can be constructed.

Summary: Novel Mn(ii)-based nanoprobes were designed with high contrast enhancement for MRI by anchoring a Mn(ii)-CDTA derivative to organo-modified silica nanoparticles. The nanoprobes showed a relaxivity gain of 250% at clinical fields and good colloidal stability in biological matrices, resulting in high image contrast in T-1w-MRI. In preliminary in vivo studies on healthy mice, the Mn-based silica nanoparticles demonstrated significant contrast enhancement in the liver, indicating their potential as high efficacy CAs for preclinical MRI applications.

Summary: Self-assembled peptide-based gels offer numerous advantages for technological applications. The co-assembly of gelators has recently emerged as a strategy to modulate and tune gel properties and achieve stimuli-responsiveness. However, there are still limitations regarding the required library of compounds and resulting properties. Therefore, efforts have been made to combine peptide-based gels with (in)organic composites to create stimuli-responsive materials with suitable properties for various fields.

Summary: Mn2+ complexes of 2,4-pyridyl-disubstituted bispidine ligands have been explored as biocompatible alternatives to Gd3+-based MRI probes. The presence of substituents on the macrocyclic nitrogens N3 and N7 is crucial for determining the conformation and properties of the complexes. In this study, the synthesis of ligands with acetate substituents in different positions was described, and it was found that N3 substitution is important for obtaining a chair-chair conformation necessary for desirable inertness and relaxivity in Mn2+ complexes.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
