“…Herein, Fmoc-blocked peptide self-assembled structures with a positively charged surface and hydrophobic core were used as templates to mediate TPPS aggregation. Because the electrostatic interaction between the core NH + and the peripheral SO 3 – groups of neighboring TPPS molecules (NH + ···–SO 3 – ) is a prerequisite for the J-aggregate arrangement, the peptide-mediated TPPS aggregation was conducted at pH 3.0 to allow the protonated dianion formation of most TPPS . If the pH of the solution was greater than the p K a of the nitrogen on the pyrrole (∼4.9), there were no J-aggregates.…”

“…The difference in the geometry of the self-assembled Fmoc-FFGK and Fmoc-ChaChaGK structures results in the distinct template effect on TPPS aggregation. In comparison with the acetyl-blocked analogs, the Fmoc-blocked peptides can self-assemble into regular nanostructures even at a relatively lower concentration, suggesting a high tendency of self-assembly as a result of increased aromatic and hydrophobic intermolecular interactions.…”

Natural photosynthesis provides a perfect example of solar energy utilization that converts CO2 to carbohydrates at high efficiency. Herein, an innovative approach was developed to construct light-harvesting antennas via the precise control of porphyrin aggregation and platinum organization on the surface of the self-assembled structures of Fmoc-blocked peptides (Fmoc-ChaChaGK-NH2 and Fmoc-FFGK-NH2). The photophysical properties and the photocatalytic activity of the antenna are dependent on the aggregating structure of porphyrin and arrangement of Pt nanoparticles, which are related closely to the molecular structure of peptides, as well as to the peptide/porphyrin molar ratio and their concentrations. The Fmoc-ChaChaGK/porphyrin complexes prepared at a peptide (Fmoc-ChaChaGK)/TPPS molar ratio of 2 and TPPS concentration of 500 μM possess the highest photo-to-electric conversion efficiency and photocatalytic ability in transforming light energy into chemical energy and storing in the energy-storage molecules (reduced nicotinamide adenine dinucleotide, NADH). The results demonstrate the correlation between the hierarchical structure and light-responsive properties of the antenna and highlight the mediating effect of noncovalent interactions in the construction and stabilization of the photoresponsive materials.

“…Xiu et al compared the co-assembly of tetrakis(4-sulfonatophenyl)porphyrin and Pt particles with similar peptides (51a-d) to understand how the peptide molecular structure influences the light harvesting system [110,111]. The Fmoc group and the Cha residue (51a) promoted the assembling and the formation of J-aggregates, enhancing the phototo-electric conversion efficiency and photocatalytic ability (NAD+/NADH conversion) of these architectures.…”

The covalent and noncovalent association of self-assembling peptides and tetrapyrroles was explored as a way to generate systems that mimic Nature’s functional supramolecular structures. Different types of peptides spontaneously assemble with porphyrins, phthalocyanines, or corroles to give long-range ordered architectures, whose structure is determined by the features of both components. The regular morphology and ordered molecular arrangement of these systems enhance the photochemical properties of embedded chromophores, allowing applications as photo-catalysts, antennas for dye-sensitized solar cells, biosensors, and agents for light-triggered therapies. Chemical modifications of peptide and tetrapyrrole structures and control over the assembly process can steer the organization and influence the properties of the resulting system. Here we provide a review of the field, focusing on the assemblies obtained from different classes of self-assembling peptides with tetrapyrroles, their morphologies and their applications as innovative functional materials.

“…It is therefore necessary to develop economical methods for NADH cofactor regeneration. To achieve this goal, chemical, photochemical, and electrochemical regeneration of NADH has been developed over the last few decades [ 122 , 144 , 145 , 146 ]. Electrochemically mediated electron injection into the enzyme not only bypasses the requirement of NADH but also simplifies product separation [ 147 ].…”

Rapid growth in the world’s economy depends on a significant increase in energy consumption. As is known, most of the present energy supply comes from coal, oil, and natural gas. The overreliance on fossil energy brings serious environmental problems in addition to the scarcity of energy. One of the most concerning environmental problems is the large contribution to global warming because of the massive discharge of CO2 in the burning of fossil fuels. Therefore, many efforts have been made to resolve such issues. Among them, the preparation of valuable fuels or chemicals from greenhouse gas (CO2) has attracted great attention because it has made a promising step toward simultaneously resolving the environment and energy problems. This article reviews the current progress in CO2 conversion via different strategies, including thermal catalysis, electrocatalysis, photocatalysis, and photoelectrocatalysis. Inspired by natural photosynthesis, light-capturing agents including macrocycles with conjugated structures similar to chlorophyll have attracted increasing attention. Using such macrocycles as photosensitizers, photocatalysis, photoelectrocatalysis, or coupling with enzymatic reactions were conducted to fulfill the conversion of CO2 with high efficiency and specificity. Recent progress in enzyme coupled to photocatalysis and enzyme coupled to photoelectrocatalysis were specially reviewed in this review. Additionally, the characteristics, advantages, and disadvantages of different conversion methods were also presented. We wish to provide certain constructive ideas for new investigators and deep insights into the research of CO2 conversion.
