Abstract The selective synthesis of thiocyanatoalkyl meth(acrylic) esters were obtained with 71 to 95 % yield under phase transfer catalysis from corresponding chloro- and bromoalkyl (meth)acrylicesters and potassium thiocyanate in presence of potassium iodide.

conveniently obtained by simple condensation of potassium cyanate with ω-halogeno-alkyl (meth)acrylates under appropriated phase transfer catalytic conditions. Depending on the reaction media and the temperature, these isocyanate derivatives may be isolated, trimerized to the corresponding isocyanurates or trapped in situ as carbamates or ureas compounds.

The covalent immobilization of the biomimetic, photo‐organocatalyst (−)‐riboflavin on silica micro‐ and nanoparticles via atom transfer radical polymerization (ATRP) is disclosed. Given the effectiveness of (−)‐riboflavin as a versatile, environmentally benign photocatalyst, an immobilization strategy based on acrylate‐linker modification of the catalyst core and controlled polymerization on initiator
Organic photovoltaic devices (OPVs) are rapidly approaching the commercialization threshold thanks to continuous advances in conversion efficiencies and device durability. Even though the design of high performing active dyes (polymeric and molecular) has dominated the literature, the formulation of strategies improving stability and processability is at least as important as the achievement of record
