Chirality in Polyoxometalate Chemistry

Abstract

The increasing use of polyoxometalates in the fields of material sciences, catalysis, and biology has raised the interest in chirality of such systems. This review provides a summary of the different strategies followed: i) chirality in solid-state arrangements, ii) chiral polyoxometalate frameworks, and iii)

Polyoxometallate als Bausteine für funktionelle Nanosysteme

“…[44] 2.3. Polyoxometallate und Chiralität [45] Das breite Anwendungsspektrum der Polyoxometallate, welches Katalyse, Biologie, Medizin, Magnetismus, Materialwissenschaften und Photochemie beinhaltet, führt zu einem großen Interesse an der Entwicklung chiraler Metalloxidstrukturen. Erste chirale POM-Cluster entstanden als Folge von Defekten und geometrischen Verzerrungen.…”

Synthesis, Structure, and Characterization of In10-Containing Open-Wells–Dawson Polyoxometalate

“…Polyoxometalates (POMs) are discrete metal oxide clusters that are of current interest as soluble metal oxides, as well as for their application in catalysis, medicine, and materials science [1][2][3][4][5][6][7][8][9][10][11][12][13]. Recently, open-Wells-Dawson POMs have been reported as an emerging class of POMs [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28].…”

Chirality meets visible-light photocatalysis in a molecular cerium vanadium oxide cluster

“…6 Over recent years, several chiral POMs were reported wherein chirality is intrinsic to the cluster framework, thereby laying the principal foundation for asymmetric POM catalysis. 7,8 In addition, POM catalysts can be driven by light as their photocatalytic activity has been pioneered by the groups of Hill, 9 Papaconstantinou, 10 Yamase 11 and others: 12 under UV-light irradiation, tungsten-and molybdenum-based POMs have been used for organic oxidations, epoxidations and C-H-activations. 9,12 Currently, efforts are underway to push the light absorption of POMs into the visible range so as to access sunlightdriven photocatalytic systems.…”
