Abstract

original image

Mehr hilft mehr: Fluoreszierende photochrome organische Nanopartikel (FPONs) aus 1 (siehe Bild) zeigen eine mit zunehmender Konzentration stark ansteigende Fluoreszenzemission sowie eine bistabile Photochromie. Ein kontrastreiches Ein/Aus-Schalten der Fluoreszenz wurde in größenabgestimmten FPONs aus 1 und in einem wiederbeschreibbaren Polymerfilm mit hoher Beladung an 1 verwirklicht.
