Abstract

Abstract : The dynamics of alkyne → copper(i ) interactions has been determined and used to self-assemble a fast nanorotor, which underwent a self-catalyzed click transformation to a triazole rotor, an interesting process for the production of biohybrid devices. Abstract : The HETPYNE (HETeroleptic Phenanthroline and alkYNE metal) and DABCO·(zinc porphyrin)2 interactions were used to assemble the four-component nanorotor ROT-1 that exhibited a highly dynamic alkyne → copper(i ) dissociation ( k 298 = 240 kHz) at 298 K. Quantitative click reaction transformed ROT-1 into the new rotor ROT-2 ( k 298 = 77 kHz) with a triazole → copper(i ) linkage thus opening perspectives for bioorthogonal click strategies to biohybrid machinery.
