“…The imidization reaction using glycine in refluxing propionic acid [ 113 ] was followed with treatment by a sodium hydroxide solution ( Figure 10 ). This PDI derivative with a maximum absorption at 525 nm in water was incorporated to reach a hybrid nanosystem composed of triple components Dextran-g-Poly(N-isopropylacrylamide)/Au nanoparticles/PDI (D-gPNIPAM/AuNPs/PDI) [ 114 ]. This system could act as a thermoresponsive fluorescent optical switch in aqueous solution in which the change in the intensity of photoluminescence was shown to result from the competing effects of plasmonic enhancement and the nonradiative FRET effect of electronic excitation energy during the thermo-induced lower critical solution temperature (LCST) transition of the D-g-PNIPAM macromolecule.…”

The emblematic perylenediimide (PDI) motif which was initially used as a simple dye has undergone incredible development in recent decades. The increasing power of synthetic organic chemistry has allowed it to decorate PDIs to achieve highly functional dyes. As these PDI derivatives combine thermal, chemical and photostability, with an additional high absorption coefficient and near-unity fluorescence quantum yield, they have been widely studied for applications in materials science, particularly in photovoltaics. Although PDIs have always been in the spotlight, their asymmetric counterparts, perylenemonoimide (PMI) analogues, are now experiencing a resurgence of interest with new efforts to create architectures with equally exciting properties. Namely, their exceptional fluorescence properties have recently been used to develop novel systems for applications in bioimaging, biosensing and photodynamic therapy. This review covers the state of the art in the synthesis, photophysical characterizations and recently reported applications demonstrating the versatility of these two sister PDI and PMI compounds. The objective is to show that after well-known applications in materials science, the emerging trends in the use of PDI- and PMI-based derivatives concern very specific biomedicinal applications including drug delivery, diagnostics and theranostics.
