Abstract

original image

Zwei in Eins: Ein an zwei photochrome Einheiten gebundenes Porphyrin fungiert als digitaler 2:1-Multiplexer (MUX). Wärme und rotes Licht sind die Eingangsdaten (ein 1 und ein 2), und ein dritter, schaltbarer Eingang (grünes Licht, sel) entscheidet, ob als Ausgang (Porphyrinfluoreszenz) der Zustand von „ein 1“ oder von „ein 2“ angezeigt wird. Jede photochrome Einheit lässt sich unabhängig so isomerisieren, dass sie die Porphyrinfluoreszenz löscht.
