ABSTRACT:
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.
