Abstract

In this work, nanoparticles of nonlinear optical organic molecular cocrystal DAST (4-dimethylamino-N-methylstilbazolium p-toluenesulfonate) were obtained by pulsed laser ablation in liquid monomer isodecyl acrylate (IDA). Sizes of obtained nanoparticles were determined by scanning electron microscope and were about 200 nm in width. Laser ablation does not lead to photocuring or photodegradation of liquid monomer. Ablation processes was similar to the processes in classical liquids (water, organic solvents). Since in this case the nanoparticles were synthesized directly in the liquid medium of the surfactant monomer, so they are stabilized in it. Nanocomposites films were synthesized on the basis of these stable colloid solution by photocuring. For aliphatic polymer IDA long molecules cross-linking 1,6-Hexandiol diacrylate was used (DIOL). Optical properties of colloid solution and nanocomposites were investigated. It was found that obtained nanoparticles are amorphous form of DAST cocrystal and have a rod-like shape. Also dodecane and polyphenelene ether were tried in this work as liquids with different viscosity to find its effect on size and shape of nanoparticles.
