“SOFT OXOMETALATES” (SOMs): A VERY SHORT INTRODUCTION

Abstract

Abstract.The field of polyoxometalates (POMs) [1] , in recent times, has entered a new arena of

New Synthetic Routes to Polyoxometalate Containing Ionic Liquids

“…Research has been focused on the development of novel materials which synergistically combine "hard" POMs with a range of "soft", mostly organic materials to form novel compounds. [45][46][47] Their usage as catalysts, sensors and electrochemically active materials is shortly discussed in this chapter, with three literature examples to give insight into the current frontiers of POM-IL research.…”

POLYOXOMETALATE-IONIC LIQUIDS (POM-ILs)–THE ULTIMATE SOFT POLYOXOMETALATES? A CRITICAL PERSPECTIVE

“…4b; 15 Until recently, POMs have hardly been connected to the¯eld of soft materials; pioneering work on soft oxometalate S. Herrmann, A. Seliverstov & C. Streb materials (SOMs) started at the end of the 20th century and has quickly developed into a thrivinḡ eld. 5 Research has been focused on the development of novel materials which synergistically combine \hard" POMs with a range of \soft", mostly organic materials to form novel compounds with soft matter properties. 5,16 In a way, liquids could be described as the ultimate soft material, and the development of the promising, yet young class of polyoxometalate-ionic liquids will be described here.…”

POM-ILs 17 are obtained when anionic POM clusters are combined with a range of organic bulky cations to give versatile materials which are liquid at or around room temperature.…”

Competitive Self-Assembly Manifests Supramolecular Darwinism in Soft-Oxometalates

“…It has been shown by us and others that each of the components of the above host-guest species [PMo 12 @Mo 72 Fe 30 ] i.e., PMo 12 and Mo 72 Fe 30 independently shows superstructured soft-oxometalate (SOM) formation by spontaneous assembly in colloidal lengthscales. 1,2,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] We have previously shown that a dilute sonicated dispersion of PMo 12 leads to the formation of peapod 37 like SOM structures. Initially, the peapods have nanosphere-type morphology and with time these spheres get converted to nanorods with nanospheres embedded inside this rod.…”
