The development and investigation of (supra)molecular‐based architectures characterized by light‐activated functionalities is a highly relevant topic of chemical research. The interest on photo‐controlled systems arises not only from their potential applications in different fields of technology but also from their scientific significance related to the understanding of light–matter interactions at the nanoscale. Indeed, light is a peculiar and unique tool as it can be conveniently applied to supply the energy required to affect and operate a system and, at the same time, to probe its state and investigate its transformations. Some basic aspects of light‐induced processes in (supra)molecular architectures are discussed here in the frame of their use to implement novel functionalities in nanostructured systems and materials. In this perspective, a few recent examples from our own work will be illustrated which are meant to provide an overview of the current directions in this highly cross‐disciplinary field of research.

“…When 1.1 equivalents of Zn 2+ ions are added, the pyridine/aniline moiety in the macrocycle and the amine in the thread complex with Zn 2+ , and the macrocycle return to the amine site. It is well known that photoinduced electron transfer takes place from the aniline and amine groups to the anthracene unit [56][57], which can be influenced by the alternation of distance between them, protonation/deprotonation and metal ion complexation/decomplexation of aniline and amine groups [58,59]. Thus, in this system, protonation/ deprotonation and metal-ion complexation/decomplexation of aniline and amine, which can induce movement of the macrocycle, will all affect the fluorescent emission of the anthracene unit.…”

The aim of this article is to explore the molecular design, synthesis and construction of molecular shuttles based on conjugated organic molecules with photo-electronic activity by self-assembly techniques. The new functions of molecular shuttles, such as switching surface properties, protecting dyes and insulating molecular wires, controlling the energy transfer, controlling nanostructural morphologies, molecular transporting and multilevel fluorescence switching, are also discussed.

“…Later on, second-generation versions of this switching principle with the photosensitizer as integral part of the ring (13) or the thread (14) were presented as well (Scheme 6.7) [32,33]. [34]. The thread of rotaxane 15 is composed of a glycylglycine dipeptide station with a nearby anthracene stopper and a long alkyl chain as solvophobic station.…”
