Five and six member ring azaheterocycles demonstrating fascinating potential applications for medicine, opto-electronics, agriculture, etc.. Molecular computers (ensemble of molecular logic devices (basically logic gates) that can process multiple signals), are miniaturized devices based on assemblies of single molecules that can execute functions on a “molecular level”. Within this work we present some core results obtained by our group in the field of podants with nitrogen heterocycles skeleton for multiple tasks: anticancer and antimycobacterial agents, fluorescent sensors, logic gates and molecular computers.
