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.

Photobistable chiral polymers were obtained by covalent attachment of inherentlydissymmetric 2-hydroxy-9-(7′methyl-1′,2′,3′,4′-tetrahydrophenanthrene-4′-ylidene)-9H-thioxanthene to methacrylate copolymers with appropriate spacers. Upon irradiation at 300 nm the opticalactivity of thin films of these polymers could be altered.
