Abstract: PURPOSE:To increase SHG and to contrive the stability at room temp. by consisting the above material of specific p-toluene sulfonic acid.1-methyl-4-[2-(4- N, N-dimethylaminophenyl)vinyl] pyridinium. CONSTITUTION:This material consists of the p-toluene sulfonic acid.1- methyl-4-[2-(4-N, N-dimethylaminophenyl)vinyl] pyridinium expressed by formula I. The p-toluene sulfonic acid.1-methyl-4-[2-(4-N, N-dimethylaminophenyl)vinyl] pyridinium can be grown to a large single crystal by a slow evaporation method. The org. crystal which has the large second harmonic wave generation (SHG) activity, is stable at room temp., and can be easily grown to the large single crystal at need is obtd. in this way.

Abstract: PURPOSE:To obtain the titled material useful as material for a light wavelength converting element, etc., stable at room temperature, readily providing large single crystal, comprising p-toluenesulfonic acid 1-methyl-4-[2-(4-hydroxyphenyl) vinyl[pyridinium. CONSTITUTION:An organic material for non-linear optical use comprising p- toluenesulfonic acid 1-methyl-4-[2-(4-hydroxyphenyl)vinyl] pyridinium shown by formula I and one comprising p-toluenesulfonyl acid 1-methyl-4-[2-(4-(N,N- dimethylamino)phenyl)] vinyl pyridinium shown by formula II. The compounds shown by formula I and formula II are synthesized by condensing 1,4- dimethylbipyridinium obtained from gamma-picoline and methyl iodide with 4- hydroxybenzaldehyde and 4-(N,N-dimethylamino)benzaldehyde through dehydration and reacting the reaction products with p-toluenesulfonic acid. Large single crystal is obtained by slow evaporation method, etc.
