Abstract

Krumme Kristalle: Große Einkristalle eines einfachen organischen kleinen Moleküls gehen ein lichtinduziertes Verbiegen ein (siehe Bild). Der Biegeprozess wird von einem starken visuellen Fluoreszenzkontrast begleitet, was für die Ferndetektion photomechanischer Arbeit genutzt werden kann.
