A series of novel monomethylated salts derived from linear benzobisthiazole was prepared The push-pull attributes of these new compounds are represented by a quaternized azolium cycle as the acceptor part at one end of the structure and the dialkylamino- or diarylamino-substituted benzene ring as the donor part at the opposite end. Both moieties are connected by a conjugated linker consisting of one or two double bonds. Such dipolar structures are promising candidates for non-linear optical materials. The quantum-chem. indexes describing linear and non-linear optical properties were obtained from semi-empirical calculations The relationships between the chem. structure and non-linear optical properties of the cations studied were obtained. Effective conjugation was confirmed by measuring the optical properties in the UV-VIS region. In the experiment, the researchers used many compounds, for example, 4-(4-Methylpiperazin-1-yl)benzaldehyde (cas: 27913-99-1SDS of cas: 27913-99-1).
4-(4-Methylpiperazin-1-yl)benzaldehyde (cas: 27913-99-1) belongs to piperazine derivatives. Industrial applications of piperazine include the manufacture of plastics, resins, pesticides and brake fluids. Piperazine is an anthelminthic especially useful in the treatment of partial intestinal obstruction caused by Ascaris worms, which is a condition primarily seen in children. Piperazine hydrate and piperazine citrate are the main anthelminthic piperazines.SDS of cas: 27913-99-1
