Abstract

The N-substituted acridinium motif is an electron-deficient unit with appealing multi-responsive properties which have been exploited in the field of supramolecular chemistry. This building block reversibly alters its shape, with its chemical and optical properties in response to a chemical or redox signal. In this Review, we discuss selected examples where the switchable properties of 9-aryl-N-methyl-acridinium lead to actuators, multi-input and multi-output systems, host or guest systems, and to interlocked systems with controllable motion.

Keywords: acridinium; host-guest chemistry; multi-output units; multi-responsive units; supramolecular chemistry.
