Summary: The noncovalent interaction of meso-aryl-substituted thiacarbocyanine dyes I and II with dsDNA and ssDNA in aqueous solutions has been studied using spectral-fluorescent methods. The formation of strongly fluorescent complexes and aggregation of the dyes accompany DNA complexation. Docking experiments confirm the formation of different types of complexes, including intercalation and groove binding. The dyes increase the melting temperatures of dsDNA and exhibit similar behavior to ethidium bromide. The limits of DNA detection and quantification have been determined for the dyes. The photochemical processes of the dyes in complexes with ssDNA have been studied, showing hindered photoisomerization and favorable conditions for the dye triplet state formation.

Summary: The researchers reported that a non-planar saddle-shaped N-heterocycle-fused metallo-porphyrinoid can directly form a persistent microporous crystalline material from solution, which can undergo solvent exchange without loss of microporosity. The material is formed by a unique accumulation of intermolecular interactions involving pi-pi stacking of the fused heterocycle, coordinative interactions at the metalloporphyrinoid unit, and hydrogen bonding. This intermolecular multipoint interaction concept will be key in the future molecular design for on-demand synthesis of porous materials, and the simple implementation of the compound described here indicates the excellent potential for device materials' synthesis. Sensing properties of the material incorporated into a nanomechanical sensor array are also reported.

Summary: Nicotine adenine dinucleotide derivatives NADH and NADPH are involved in energy and electron transport in cells. The fluorescent ubiquinone-rhodol probe Q-Rh is used to monitor NADPH activation, and the addition of an Ir-III-complex promotes the activation. Experiments show that the reduction rate of Q-Rh is increased in HeLa cells especially with the addition of the Ir-III-complex promoter, involving the nonspecific activation of other intracellular reducing agents.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
