Photochemical Synthesis of Nonlinear Optical and Photorefractive Materials
Abstract:Photochemical formation of image with nonlinear optical and photorefractive properties in polymer layers is displayed. The layers were obtained using composition of polyhydroxyaminoether containing aromatic amino groups in polymer chains and tetrabromomethane. Donor-acceptor complexes form in the layers and irradiation of the layers by light in the range 330-450 nm stimulates electron transfer from the donor to the acceptor leading to the synthesis of colored polycation product which possesses the nonlinear optical and charge carrier photo-generating properties. Besides, these layers are electron-transporting ones. All of it allowed to obtain light-sensitive layers for recording nonlinear optical and photorefractive images and patterns.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
