“…These systems can be suitable for performing synchronously as a whole unit, integrating donor and acceptor chromophoric units in their structure [129]. In addition, their well-defined branched architectures would allow for various chromophore arrays with relative positions and orientations to create one-step or multi-step gradients (cascades) of energy and spatial focalization of the excitation energies [130]. These are relevant aspects since they condition the system's behavior concerning the harvesting of light and the efficiency of the energy-transfer processes.…”

Dendrimers (from the Greek dendros → tree; meros → part) are macromolecules with well-defined three-dimensional and tree-like structures. Remarkably, this hyperbranched architecture is one of the most ubiquitous, prolific, and recognizable natural patterns observed in nature. The rational design and the synthesis of highly functionalized architectures have been motivated by the need to mimic synthetic and natural-light-induced energy processes. Dendrimers offer an attractive material scaffold to generate innovative, technological, and functional materials because they provide a high amount of peripherally functional groups and void nanoreservoirs. Therefore, dendrimers emerge as excellent candidates since they can play a highly relevant role as unimolecular reactors at the nanoscale, acting as versatile and sophisticated entities. In particular, they can play a key role in the properties of light-energy harvesting and non-radiative energy transfer, allowing them to function as a whole unit. Remarkably, it is possible to promote the occurrence of the FRET phenomenon to concentrate the absorbed energy in photoactive centers. Finally, we think an in-depth understanding of this mechanism allows for diverse and prolific technological applications, such as imaging, biomedical therapy, and the conversion and storage of light energy, among others.

“…In most photosynthetic organisms such as plants, algae, and photosynthetic bacteria, the rigid protein scaffolds serve as key elements to bind pigments and control their excitation energy transfer. Until now, a variety of artificial sequential energy transfer systems have been developed to mimic nature, by anchoring donor/acceptor (D/A) chromophores to the scaffolds including vesicles 6 – 8 , micelles 9 , 10 , macrocycles 11 , 12 , biomacromolecules 13 – 19 , and supramolecular gels 20 – 23 . However, most of the examples exhibit the overall energy transfer efficiency (Φ overall ) lower than 70% 6 – 23 , lower than the natural LHSs of purple photosynthetic bacteria (Φ overall : close to unity) 5 .…”

Sequential energy transfer is ubiquitous in natural light harvesting systems to make full use of solar energy. Although various artificial systems have been developed with the biomimetic sequential energy transfer character, most of them exhibit the overall energy transfer efficiency lower than 70% due to the disordered organization of donor/acceptor chromophores. Herein a sequential energy transfer system is constructed via supramolecular copolymerization of σ-platinated (hetero)acenes, by taking inspiration from the natural light harvesting of green photosynthetic bacteria. The absorption and emission transitions of the three designed σ-platinated (hetero)acenes range from visible to NIR region through structural variation. Structural similarity of these monomers faciliates supramolecular copolymerization in apolar media via the nucleation-elongation mechanism. The resulting supramolecular copolymers display long diffusion length of excitation energy (> 200 donor units) and high exciton migration rates (~1014 L mol−1 s−1), leading to an overall sequential energy transfer efficiency of 87.4% for the ternary copolymers. The superior properties originate from the dense packing of σ-platinated (hetero)acene monomers in supramolecular copolymers, mimicking the aggregation mode of bacteriochlorophyll pigments in green photosynthetic bacteria. Overall, directional supramolecular copolymerization of donor/acceptor chromophores with high energy transfer efficiency would provide new avenues toward artificial photosynthesis applications.

“…Using stimuli‐responsive optical materials to use sunlight represents a smart approach to ALHS devices because FRET can now be used to transform energy output. [ 19 ] Here, we describe the successful construction of a new solar‐electrical conversion device that differs from traditional solar cells. [ 20 ] To the best of our best knowledge, this is the first report to describe the use of a FRET‐active ALHS, which uses multiple conversion processes (light‐harvesting, FRET, photothermal, and thermoelectric conversion) for sequential photo‐thermo‐electric conversion (Figure 1).…”

Light is essential to all life on the earth. Thus, highly efficient light‐harvesting systems with the sequential energy transfer process are significant for using solar energy in photosynthesis. For developing an efficient light‐harvesting system, a liquid aggregation‐induced emission (AIE) dye TPE‐EA is obtained, as a donor and solvent, which can light up the aggregation caused quenching (ACQ) Nile Red (NiR, acceptor) to construct a quantitative Förster resonance energy transfer (FRET) system in NiR⊂TPE‐EA. Impressively, this FRET pair shows an impressive photothermal effect, producing a peak temperature of 119 °C while excited by UV light, with 37.8% of conversion efficiency. NiR⊂TPE‐EA is quite different from most other photothermal materials, which require excitation with long wavelength light (>520 nm). Therefore, NiR⊂TPE‐EA firstly converts the solar into thermal energy and then into electric energy to achieve sequential photo‐thermo‐electric conversion. Such sequential conversion, suitable for being excited by sunlight, is anticipated to unlock new and smart approaches for capturing solar energy.
