Different types of molecular and nanoscale fluorophores are being developed for fluorescent imaging of live cells. Here we present their novel types and novel compositions. The dyes incorporated into nanostructures and their metal coordination complexes as well as carbon nanodots penetrate easily into the cell with the lack of toxicity, forming stable images. They are prospective for further fu...

Interactions between aspartic acid (Asp) and cytidine-5-monophosphate (CMP) in metal-free systems as well as the coordination of Cu(II) ions with the above ligands were studied. The composition and overall stability constants of the species formed in those systems were determined by the potentiometric method, and the interaction centres in the ligands were identified by the spectral methods UV-...

Crystal structures and dynamic rearrangements of one-dimensional coordination polymers with 4,4'-dipyridylsulfide (dps) have been studied. Reaction of Ni(NO(3))(2)·6H(2)O with dps in EtOH yielded [Ni(dps)(2)(NO(3))(2)] ·EtOH (1), which had channels filled with guest EtOH molecules among the four Ni(dps)(2) chains. This coordination polymer reversibly transformed the channel structure responding...

By the combination of different metal salts and solvents, four unprecedented in situ reactions have been discovered for heterocyclic disulfide of 2-ppds (2-ppds = di[4-(pyridin-2-yl)pyrimidinyl]disulfide). In the CH3CN-DMF solvent, reaction of 2-ppds with AgNO3 produced a one-dimensional chain structure of {[Ag2(1L)2]·2CH3CN}n (1), wherein 2-ppds was converted into its sulfonate of 1L by means ...

This study investigated the effect of reaction time (minutes to months) on the surface coordination environment of Ni sorbed onto pyrophyllite using XAFS. The data suggest the appearance of multinuclear Ni complexes after a reaction time of minutes. As reaction time !>rogresses, these multinuclear Ni complexes increased in size «NNi-Ni 1.4-4.5). Ni-Ni bond distances (2.99-3.03 A) were similar t...

Platinum phenanthroline complexes have been found to inhibit Aβ aggregation and reduce Aβ caused neurotoxicity. Our previous results revealed the synergistic roles of phenanthroline ligand and Pt(ii) coordination in the inhibition of Aβ aggregation. In this work, the reactions of PtCl2(phen) with metal bound Aβ complexes were investigated. HPLC results show that the copper coordination decrease...
