摘要： Of hydrogen atoms constituting 2-adamantylamino-5-nitropyridine, at least hydrogen atom of N--H part is substituted with deuterium to obtain a deuterated AANP. An organic optical material is made from the deuterated AANP. Content of the deuterated AANP in this case is preferably more than 25%. With this method, an organic nonlinear optical material can be provided for devices having a large wavelength conversion efficiency in wavelength conversion relating to optical communications wavelength region, particularly at and around 1.55 .mu.m wavelength.

摘要： In a sealed system, a polymerization initiator and a chain transfer agent are added to a methyl methacrylate monomer distilled under reduced pressure condition via a distillation step of the former both ingredients, the methyl methacrylate monomer is successively polymerized to prepare a core polymer while maintaining the reduced pressure condition, then the resulting core polymer is subjected to melt spinning to form a core fiber while maintaining the sealed system, and a clad of a macromolecular compound having a refractive index lower than that of the aforesaid core fiber is adhered around the periphery thereof, whereby a low-loss plastic optical fiber with excellent optical transmission characteristics having a core-cladding structure is fabricated. Plastic optical fibers so made exhibit light attenuation as low as 60 dB/km or lower.
