Second harmonic generation 3-methyl-4-nitroaniline

Optical processing systems are proposed based on relative intensity changes of second harmonic generation in sorbate complexes of p-nitroaniline and 2-methyl-p-nitroaniline in molecular sieve hosts [98]. Optical data storage would be one of a variety of potential electro-optical applications. In addition, molecular optical effects by third harmonic generation are suggested for optical data storage based on the possible formation of bistabilities for the local fields [65,99]. 

Phase-matched second harmonic generation in single crystal polymers was first observed in 2-methyl-4-nitroaniline substituted diacetylene polymers. Subsequently, a number of other diacetylene structures... 

ABSTRACT. Second harmonic generation(S.H.G.) in inclusion complexes between dimethyl-cyclodextrin(dimethyl -CD) and nitroaniline derivatives occurs. This is due to the destruction of the centrosyimntric crystal structure in nitroaniline derivatives caused by forming inclusion complexes. S.H.G. intensity of dimethyl /-CD complex with N-methyl-nitroaniline is 5 5 times as large as that of urea.
