Diarylethenes for Memories and Switches

Synthetic Principles for Bandgap Control in Linear pi-Conjugated Systems.

Helicenes: synthesis and applications.

Reversible Photocontrol of Biological Systems by the Incorporation of Molecular Photoswitches

Two-dimensionally extended, polycyclic heteroaromatic molecules (heterocyclic nanographenes) are a highly versatile class of organic materials, applicable as functional chromophores and organic semiconductors. In this Review, we discuss the rich chemistry of large heteroaromatics, focusing on their synthesis, electronic properties, and applications in materials science. This Review summarizes the historical development and current state of the art in this rapidly expanding field of research, which has become one of the key exploration areas of modern heterocyclic chemistry.
