Zinc bis(allyldithiocarbamate) for highly refractive and flexible materials via the thiol-ene reaction

Abstract

Novel zinc bis(allyldithiocarbamate) (Zn(ADTC)2) complexes, prepared from allylamines, carbon disulfide and zinc nitrate, were applied for the synthesis of highly refractive materials. Transparent and flexible films were prepared by the thiol-ene reaction of Zn(ADTC)2 derivatives with a tetrathiol and a diacrylate initiated with Irgacure 651. The refractive index of the films increased with the feed ratio of the Zn(ADTC)2 derivatives. The calculated n D values of the components originating from the two Zn(ADTC)2 complexes were 1.71 and 1.67.
