HYBRID MOLECULES OF COUMARINÙ(BENZO-IMIDAZO-INDOLIZINE) WITH NON-LINEAR OPTIC PROPERTIES.

摘要

The present invention describes the design of organic molecules of the push-pull type. The invention describes the synthesis of novel compounds derived from coumarin-benzo-imidazo-indolizine. The obtained molecules were evaluated as materials with non-linear optic properties of the third order. The synthesis process resulted to be efficient (5 min to 24 h) upon using alternate sources of microwave and infrared energy, also being effective due to the high chemical yield in the different stages of the synthesis (30% to 98%). The coumarin-benzo-imidazo-indolizine molecules have an excellent non-linear property since they require a minimum energy (1-9mW) for emitting the formation of self-diffraction rings (5-17); the molecules may be used as cell trackers, in the visualization and quantification of heat, generation and manufacture of wave guides in communication systems and optic switches, and in the manufacture of sensors.
