A small molecule was designed for reactivity toward Cu(ii)–amyloid-β over Zn(ii)–amyloid-β, which will expand on the development of chemical tools to uncover the role of metal–Aβ species in Alzheimer's disease.

intramolecular protontransfer via a six number-membered ring transition state. In contrast, it cannot be processed through five- and seven-number-membered ring transitionstates of the studied dyes. The molecular geometry optimization of the studied dyes reveals fundamental factors for the difficulties of intramolecular protontransfer in excited states via five- and seven-number-membered ring transition states
