Molecular Switches
Beilstein Organic Chemistry Symposium 2014

24 – 26 September 2014
Yachthotel Chiemsee, Prien (Chiemsee), Germany

Introduction

The Beilstein Organic Chemistry Symposium 2014 is dedicated to "Molecular Switches" and will bring together ca. 50 experts in the field. It will be held September 24–26th, 2014 in Prien, Germany on the shores of lake Chiemsee. The meeting is intended to stimulate fruitful discussions between colleagues that focus on basic physical and chemical aspects of molecular switches and those who are primarily interested in their application in complex systems.

The symposium is organized by the Beilstein-Institut and has been inspired by the Thematic Series "Molecular switches and cages" published in the Open Access Beilstein Journal of Organic Chemistry and edited by Dirk Trauner.

Molecular switches toggle between two or more states that interact with their environment in different ways. As the chemistry of well-known representatives, such as azobenzene or diarylethenes, is refined and new types are discovered, molecular switches increasingly find useful applications in the materials sciences and in biology. The conference will cover a variety of aspects, including the synthesis of molecular switches, their (photo)physical characterization, their stability and reversibility,  their incorporation, spatial and temporal addressability, and their ability to control highly complex systems such as neural circuits, microbial societies, or the tracks and motors that underlie cellular migration and division. The question of how synthetic molecular switches relate to those found in biology will receive special attention at the conference.
