Abstract

original image

Säurespezifische Konformationsänderungen: Die Protonierung von meso-Aryl-substituiertem Rubyrin 1 mit HCl und CF3CO2H bewirkt unterschiedliche Konformationsänderungen, wie die Verschiebungen der UV/Vis-Absorptionsbanden relativ zu denen der freien Base belegen (Cl: Blauverschiebung; CF3CO2: Rotverschiebung). Die deutlichen Gegenion-abhängigen Farbänderungen bei der Säurezugabe zum „Anionensensor“ 1 lassen sich einfach nachweisen.
