Crystallography and Properties of Polyoxotitanate Nanoclusters

Structure and Properties of a (CdSe)6@(CdSe)30Cluster Doped with Mn Atoms

“…The Mn substituent atom occupies the former site of a Se atom and pushes this Se atom out of the cluster, as we already observed in the case of the Cd 9 MnSe 8 substituted clusters. 28 It is interesting to note that Mn is capable to push out a Ti atom in polyoxititanate nanoclusters (see Ref [60]. Fig.…”

Construction of molecular rectangles with titanium–oxo clusters and rigid aromatic carboxylate ligands

“…[16][17][18] Along this line, polyoxo-titanium clusters (PTCs) have been attracting much research attention in recent years, because they possess well-defined structures and can be used as reactivity model compounds of TiO 2 nanoparticles. [19][20][21][22][23][24][25] Another major advantage of PTCs is that they can be easily functionalized by organic ligands. 26 In the course of our research on titanium-oxo clusters, recently, we successfully applied a variety of bridging ligands to organize the 0D {Ti 6 3 ) is observed that has been reported earlier in many molecular clusters ( Fig.…”

Photochemistry — development and achievements

“…Femtosecond techniques provide valuable information about both physical processes (kinetics of electronic deactivation and vibrational relaxation) and chemical reactions (formation and reactions of intermediates). It should be pointed out that current techniques allow scientists also to determine the structure of electronically excited molecules and nanoparticles (Coppens et al, 2002;Coppens et al, 2014). It should be pointed out that outcomes of attosecond (photo)physics penetrate to chemistry providing valuable information on the electron dynamics connected to chemical processes (Nisoli et al, 2017;Kumpulainen et al, 2017).…”
