"s-Heptazines – heterocycles with interesting properties and versatile potential applications"

Abstract

s-Heptazines, i;e compounds containing the tricyclic aromatic building block C₆N₇ have been discovered in the 1830s. We investigated synthesis routes to symmetric and asymmetric deritatives. The fact, that s-heptazine polymers like melon [C₆N₉H₃]n were found to be semiconductors and (photo)catalysts initiated a lot of research activities in recent years. Molecular derivatives might also be useful (photo)catalysts. We observed that some derivatives show (photo)luminescence while others might be useful flame retardants.

"Photo- and redox- active artificial molecular machines and motors"

Abstract

We will describe here some recent investigations undrtaken in our laboratory on photo- and electroactive molecular devices, based on two classes of molecules, which are endowed with peculiar features for the design of directionally controlled motors.
