Abstract:

A literature search focusing on the utilization and the synthesis of push-pull systems based on pyridinium betaines has been carried out. The utilization of these compounds is based on their NLO properties. The synthetic part of this work focuses mainly on pyridinium betaines substituted with electron-donor N,N-dialkylamino group and linked through different đ-linkers. 1-methyl-4-N,N-dialkylaminopyridinium iodide (1) can be prepared in a one-step synthesis. This was experimentally verified in the preparation of specific derivate 1-methyl-4-N,N-dimethylaminopyridinium iodide (26). 1-methyl-4-[4'-(N,N-dialkylamino)phenylethynyl]pyridinium iodide (2) can be prepared in a three-step synthesis. This was also verified in the preparation of 1-methyl-4-[4'-(N,N-dimethylamino)phenylethynyl]pyridinium iodide (28). Analogical preparations of 1-methyl-4-[2-(4'-N,N-dialkylaminophenyl)azo] pyridinium iodide (3) and 1-methyl-4-(4'-N,N-dialkylaminophenyl)pyridinium iodide (4) were also verified in preparation of 1-methyl-4-[2-(4'-N,N-dimethylaminophenyl)azo] pyridinium iodide (30) and 1-methyl-4-(4'-N,N-dimethylaminophenyl)pyridinium iodide (32) respectively.
