“…In 2017, Ye et al reported a highly efficient FRET process from aggregation-induced emission to BODIPY emission based on hostguest interaction for mimicking the LHS [46]. In this work, AIE luminogen tetraphenylethene (TPE) was chosen to combine with crown ether moieties as a host (M1) and energy donor in FRET system (Scheme 1).…”

Artificial light-harvesting systems (LHSs) have drawn increasing research interest in recent times due to the energy crisis worldwide. Concurrently, macrocycle-based host-guest interactions have played an important role in the development of supramolecular chemistry. In recent years, studies towards artificial LHSs driven by macrocycle-based host-guest interactions are gradually being disclosed. In this mini-review, we briefly introduce the burgeoning progress of artificial LHSs driven by host-guest interactions. We believe that an increasing number of reports of artificial LHSs driven by host-guest interactions will appear in the near future and will provide a viable alternative for the future production of renewable energy.

“…In contrast to the aforementioned examples of the pH‐responsive supramolecular polymers or complexes, a pH stable fluorescence resonance energy transfer (FRET) system has been constructed for mimicking light harvesting based on the host–guest interaction between crown‐ether modified TPE as a FRET donor and boron‐dipyrromethene (BODIPY) as the energy acceptor bearing benzylamino group and triazole unit as two binding sites . FRET is an electrostatically intermediated energy transfer process.…”

host and guest bears excellent selectivity. [5] On the other hand, the noncovalent interactions are sensitive to various influential elements in the surrounding environment, including light irradiation, [6] redox reactions, [7] pH variations, [8] competitive factors, [9] and chemical or biological interfering. [10,11] Owing to the highly desired characteristics of host-guest systems comprising of supramolecular macrocycles and their guests, the dynamic nature of their molecular activities, the reversibility between assembly and disassembly, the particular intermolecular recognition and the responsiveness toward external stimuli, supramolecular host-guest systems become outstanding candidates as building blocks in the construction of nanoscaled smart materials with controllable properties, which are substantial in the research ranges of nanotechnology and materials science. Up till today, a number of host compounds, such as crown ethers, [12,13] cyclodextrins (CDs), [14] calixarenes, [15] cucurbit[n]urils (CB[n]s), [16][17][18] and pillararenes, [19,20] on account of their developed synthetic procedures, relatively high yieldings, numerous modification possibilities and tunability, [21,22] along with their well-explored host-guest properties, [5] have been utilized to construct stimuliresponsive smart materials to serve as either supramolecular recognizing agents or the major building blocks for reversible artificial complexes. [1,23,24] An important use of macrocyclic compounds to create functional smart materials lies in the construction of controllable fluorescent systems. [25] In the literature, one can find considerable examples of fluorescent systems manipulated by supramolecular macrocycles through their distinctive inclusion complexation activities. [26][27][28][29] The concept of aggregation-induced emission (AIE) was first proposed by Tang and co-workers in 2001, [30] demonstrating an unprecedented fluorescent phenomenon, which bears luminescent features in sharp contrast to the traditional aggregation-caused quenching (ACQ) that is typical for conventional organic fluorophores. While the ACQ effect stands as a major hindrance for the solidation of luminescent materials since luminophores with planar molecular structures undergo fluorescence quenching in aggregated state, dye molecules possessing unplanar conformations, on the contrary, are able to exhibit stronger emission upon aggregation according to the restriction of intramolecular motions (RIM) or rotations (RIR), which suppresses nonradiative relaxation and actuates the energy release through radiative pathway. [31,32] Two essential elements of smart materials are their capabilities of responding to external stimuli and the specific recognition toward different targets, which renders supramolecular macrocycles an ideal type of building blocks for materials construction. Aggregation-induced emission (AIE) has been intensively investigated for two decades not only for the realization of solid-state fluorescent materials, but also for the fabrication...

“…Photochromic molecules have attracted considerable attention due to their potential applications in optical memories, , molecular switches, , and super-resolution imaging. − Dithienylethene (DTE)-based photochromic derivatives have been extensively studied because of their thermal bistability and fatigue resistance enabling nondestructive readout for optical memories. − To realize a nonvolatile optical memory, several methods have been proposed, such as readout with IR absorption, optical rotation, supramolecular conformational changes, and fluorescence switching. , Fluorescence quenching of DTE-based photochromic derivatives is attributed to two mechanisms: fluorescence resonance energy transfer (FRET) − and photoinduced electron transfer (PET). − DTE-based photochromic derivatives can obtain reversible photochromism and fluorescence switching via FRET with a high fluorescence on/off ratio and fatigue resistance . However, FRET inherently induces the photochromic reverse reaction of the ring-closed form to the ring-open one during fluorescence readout. , Thus, such systems are detrimental to nonvolatile optical memories due to the crosstalk between reading and writing/erasing wavelengths.…”

A near-infrared fluorescence-switchable molecule, dithienylethene-terrylenediimide (TDI-4DTE) exhibits high near-infrared fluorescence and on/off ratio, decent reversibility, and fatigue resistance upon alternating UV/vis (305/621 nm) irradiation. Photoinduced electron transfer mainly contributes to the fluorescence quenching of TDI-4DTE. As an information storage unit, single molecular TDI-4DTE in the polymer film can be written by red light (621 nm) and erased by UV light (305 nm), while nondestructive fluorescence readout (750 nm) of a single molecular memory has been obtained upon excitation with near-infrared light (720 nm). The fluorescence patterning of TDI-4DTE in the polymer film demonstrates that the erasing/writing/reading wavelengths are deciphered to minimize the signal crosstalk in nonvolatile fluorescent molecular memories.
