Abstract

Wellenreiten: Ein Aldehyd löst die orientierte Kristallisation selbstorganisierender fibröser Diphenylalanin-Peptidnetzwerke über große Entfernungen aus (siehe Bild). Das Kristallwachstum ist selbstregelbar und wird wahrscheinlich kinetisch reguliert, was zu dreidimensionaler Beschränkung uniaxial orientierter Unterstrukturen im resultierenden Kristall führt. Die Peptidkristalle zeigen bemerkenswerte thermische Stabilität und optische Wellenleitung.
