A newly designed softoxometalate [BMIm]₂[DMIm][α-PW₁₂O₄₀]@hydrocalumite that controls the chain length of polyacrylic acid in the presence of light

Abstract

We have controlled the radical as well as cationic polymerization of acrylic acid using [BMIm]2[DMIm][α-PW12O40]@hydrocalumite (SOM 2) as a photocatalyst.

In situ self-assembly and photopolymerization for hetero-phase synthesis and patterning of conducting materials using soft oxometalates in thermo-optical tweezers

“…We demonstrated earlier that such a micro-bubble formed on a glass substrate drives self assembly of mesoscopic material in an aqueous dispersion due to hydrodynamic (Marangoni) flows caused by the temperature (and the resultant surface tension) gradient across the bubble. 21 At the core of the process is a soft oxometalate (SOM) material [22][23][24][25][26] which absorbs at the laser wavelength of 1064 nm to form a micro-bubble. SOMs self-assembled at the bubble base subsequently undergo a phase transition from the soft to crystalline state 21 as the bubble is translated by the optical tweezers.…”

Light driven decarboxylative cross coupling of acrylic acid and iodobenzene using [Mo 132 ] type keplerate as a catalyst

“…We have already shown that this cluster is photoactive and it acts as a catalyst in photochemical dimerization followed by oxidation reaction of styrene [42]. Now here we have shown that acrylic acid gets decarboxylated in the reaction medium and further couples with iodobenzene to form styrene in reaction mixture using [Mo 132 ] as a photocatalyst.…”

“…Also polyoxometalates are photoactive and generally stable under photochemical conditions. POMs have been used as photocatalyst in different photopolymerization reaction and organic reactions by us already [38][39][40][41][42]. Thus we are now interested to use those giant POMs in photo catalytic organic coupling reaction.…”

Light Driven Water Oxidation Coupled With C‐N Coupling Reaction Using a Hybrid Cu‐PW12O40 Based Soft‐Oxometalate

“…We have used SOM 1 as a photocatalyst for photochemical water oxidation coupled with organic reactions. We have previously shown the photocatalytic activity of the phosphotungstate based inorganic material . The photocatalytic experiments are performed without any external photosensitizer.…”
