“…Mimicking a powerhouse cell by reconstitution of the ETC system onto a membrane is not a new idea; it first appeared in 1977. Although the protocol can vary from group to group, the main components are an appropriate interface (formed from lipids, polymers, or hybrids [119] ), a proton pump or photoacid/ photobase generator, [110,114] and ATP synthase. [4a,106a,120] An appropriate interface can be achieved from different building blocks, such as natural and synthetic lipids, three-block copolymers, or hybrid materials.…”

The demand to discover every single cellular component has been continuously increasing along with the development of biological techniques. The bottom‐up approach to construct a cell‐mimicking system from well‐defined and tunable compositions is accelerating, with the ultimate goal of comprehending a biological cell. From among the available techniques, the artificial cell has been increasingly recognized as one of the most powerful tools for building a cell‐like system from scratch. This review summarizes the development of artificial cells, from a pure giant unilamellar vesicle (GUV) to a controllable, self‐fueled proteoliposome, both of which are highly compartmentalized. The basic components of an artificial cell, as well as the optimal conditions required for successful, reproducible GUV formation and protein reconstitution, are discussed. Most importantly, progress in studying the metabolic reactions in and the motility of a reconstituted artificial cell are the main focus of the review. The ability to perform a complicated reaction cascade in a controllable manner is highlighted as a promising perspective to obtaining an autonomous and movable GUV.

“…Increasing the photocatalyst surface area by processing bulk semiconductors into NPs or nanofibers is a simple and commonly employed strategy to increase their EQE. [9,244,245,264,[275][276][277][278][279] Other strategies include designing porous semiconductors such as conjugated microporous polymers and covalent-organic frameworks (COFs) which can allow ingress of hole or electron scavengers into the semiconductor pores. [8,[280][281][282] If the photocatalyst needs to operate in a liquid matrix, efficient wetting of the pores by the solvent/scavenger solution is essential to maximize efficiency.…”

Organic semiconductors require an energetic offset in order to photogenerate free charge carriers efficiently, owing to their inability to effectively screen charges. This is vitally important in order to achieve high power conversion efficiencies in organic solar cells. Early heterojunction‐based solar cells were limited to relatively modest efficiencies (<4%) owing to limitations such as poor exciton dissociation, limited photon harvesting, and high recombination losses. The development of the bulk heterojunction (BHJ) has significantly overcome these issues, resulting in dramatic improvements in organic photovoltaic performance, now exceeding 18% power conversion efficiencies. Here, the design and engineering strategies used to develop the optimal bulk heterojunction for solar‐cell, photodetector, and photocatalytic applications are discussed. Additionally, the thermodynamic driving forces in the creation and stability of the bulk heterojunction are presented, along with underlying photophysics in these blends. Finally, new opportunities to apply the knowledge accrued from BHJ solar cells to generate free charges for use in promising new applications are discussed.

“…However, these Pdots appeared to be stable for a maximum of 4 h with high roll‐off efficiency. Surprisingly, the same groups reported hollow structured Pdots prepared using conjugated polymer PFODTBT and 8‐hydroxypyrene‐1,3,6‐trisulfonic acid trisodium salt (HTPS) as the copolymer instead of PS−PEG−COOH for hydrogen evolution . Notably, the photocatalysis enhancement mainly depended on the decrease in particle size from 90 to 5 nm.…”

“…Surprisingly, the same groups reported hollow structured Pdots prepared using conjugated polymer PFODTBT and 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HTPS) as the copolymer instead of PSÀ PEGÀ COOH for hydrogen evolution. [92] Notably, the photocatalysis enhancement mainly depended on the decrease in particle size from 90 to 5 nm. Overall, this work revealed that nature-mimicking hollow Pdots with porous shells could be ideal photocatalysts applicable in solar energy conversion and storage systems.…”

Efficient polymer photocatalysts that mimic natural photosynthesis to generate H 2 through the visible-light-promoted splitting of water are ideal systems for the conversion of solar energy into usable fuel with high energy density and in an environmentally friendly manner. In this article, we review recent reports on donor-acceptor-based π-conjugated polymers as photocatalysts, including conjugated linear polymers, microporous polymers, triazine frameworks, covalent organic frameworks, polymer dots, and other related organic polymers, which show superior photocatalytic activity and robust stability under visible-light irradiation, for hydrogen production. Moreover, their syntheses and material design strategies, photophysical properties, proposed mechanisms, and applications are systematically summarized. Finally, recent research on and challenges related to organic polymer photocatalysts are discussed. This minireview will help readers to more easily understand the recent advances in and future direction of this field.
