Abstract: NEW MATERIAL:A compound shown by the formula I (R is H, or methyl; R is 10-20C straight-chain alkyl). EXAMPLE:N-Octadecyl-2-methyl-4-nitroaniline. USE:Useful for producing an optical element having highly active laser. PREPARATION:A 4-nitroaniline shown by the formula II or 2-methyl-4- nitroaniline is reacted with an alkylating agent shown by the formula X-R (X is strong acid residue) in the presence of an alkali (e.g., Na, K, NH3, pyridine, etc.), to give a compound shown by the formula I. An alkyl chloride, alkyl bromide, etc., may be cited as the alkylating agent. The compound shown by the formula I is useful for forming an accumulated film having a functional group showing specifically optical characteristics.

Abstract: PURPOSE:To obtain a nonlinear optical org. material which has the second harmonic waves generation as large as several times that of urea, is stable at room temp. and is easily growable to a large single crystal by using specific 4-amino-4'-nitrobiphenyl as said org. material. CONSTITUTION:The 4-amino-4'-nitrobiphenyl expressed by the formula I is the single crystal without having a symmetrical center and, therefore, exhibits the second harmonic wave generation (SGH) activity of several times that of urea and is stable at room temp. Said material generates the second harmonic waves (SHG) and generates green light of the wavelength (532mum) of half the wavelength of incident light when measurement is made by projection of Nd: YAG laser (wavelength = 1064mum, output 3mJ/pulse) in the powder state. This material is growable to a single crystal of mm order. The org. crystal which has the large SHG activity, is stable at room temp. and is easily growable to the large single crystal at need is thereby obtd. This crystal is adequate as a material for light wavelength conversion elements, optical shutters, high- speed optical switching elements and optical logical gates as well as the stock for optical transistors, etc.

Abstract: PURPOSE:To obtain the titled material having a large 2nd high frequency generating capacity (SHG) and a high stability at a room temp. and a large-sized monocrystal by incorporating a specific org. compd. to the titled material. CONSTITUTION:The titled material comprises a 2-amino fluorenone shown by formula I or a 4-amino-4'-nitrobiphenyl shown by formula II. The prescribed compds. may grow to the large monocrystal by a slow evaporation method. The prescribed compds. has a SHG larger than that of an urea by few times and has a good stability at the room temp. and may be easily grown to the large monocrystal. Thus, the titled material is used for materials of an optical wavelength conversion element, an optical shutter, a high switching element, a optical logical gate and an phototransistor.
