“…[60][61][62][63][64][65] We have also demonstrated that homogeneous 3D porous supramolecular organic frameworks can exhibit an important confinement effect for homogeneous photocatalysis in aqueous media. [66][67][68][69] The high stability of CBSP allows it to maintain a nanoscale size at micromolar concentrations of the building blocks. We thus studied the capability of CBSP for simultaneous enrichment of the photosensitizer Na 4 [Ru(BDC) 3 ] (PS, BDC = 2,2′-bipyridyl-4,4′-carboxylate) (Scheme 1) and the Keggin-type polyoxometallate catalyst Na 3 PW 12 O 40 (POM), which forms an important integrated photocatalytic system for visible light induced reduction of protons into H 2 .…”

“…[34] CB [8] is established as a rigid macrocycle that can induce self-assembly to form supramolecular polymers from organic monomers. [117][118][119] They designed and synthesized 24 and 25 consisting of multiple viologens and azobenzene functional groups. Supramolecular 2D materials based on ternary complexes can provide derivatives 24 and 25 upon the addition of CB [8].…”

the construction of functional 2D materials by the self-assembly of synthetic building blocks such as amphiphilic block copolymers, [10] lipid molecules, [11] deoxyribonucleic acids (DNAs), [12] rod-coil amphiphiles, [13] and oligopeptides. [14] Among diverse self-assembling modules, aromatic amphiphiles can serve as remarkable candidates for the creation of well-defined supramolecular 2D structures owing to their rigidity and the π-π stacking of aromatic groups. [15-17] In self-assembled 2D structures composed of aromatic amphiphiles, the rigid aromatic segments surrounded by hydrophilic flexible chains can form relatively stable noncovalent interactions in a preferred direction. [18] Besides, the packing arrangements of aromatic segments can reversibly transform into a different equilibrium state when subjected to subtle environmental changes, demonstrating a distinct adaptive capability of dynamic shape alterations. [19] Therefore, the supramolecular 2D materials formed by aromatic amphiphiles hold promise in biological applications because the physical and chemical properties of the supramolecular 2D structure, which are attributed to the large surface area of these materials, can enhance the detection sensitivity of target molecules and increase the molecular loading and bio-conjugation efficiency. Furthermore, the flexibility, low toxicity, dispersibility, and permeability offered by 2D materials can contribute to the development of the next generation of functional materials in biological systems. [20-25] In this regard, several types of studies have been conducted on supramolecular 2D materials with biological applicability because supramolecular systems are more convenient for the fabrication of materials with multiple functionalities for biology applications. [26-34] Herein, we summarize supramolecular 2D materials based on the corresponding aromatic amphiphiles and discuss several of their biological applications (Figure 1). We classified the strategies of self-assembly of the 2D structure as follows: direct assembly of monomers and assembly in a stepwise manner via primary structures. In the direct assembly strategy, the aromatic amphiphilic blocks are assembled into 2D structures without transition into an intermediate state, in which the monomers are directly arranged in parallel, zigzag, or hexagonal conformations through hydrophobic, hostguest, and electrostatic interactions. However, in the stepwise assembly strategy, the monomers are assembled into primary structures such as dimeric micelles and fibers in the initial state, which is followed by lateral interactions to 2D structures. Various biological systems rely on the supramolecular assembly of biomolecules through noncovalent bonds for performing sophisticated functions. In particular, cell membranes, which are 2D structures in biological systems, have various characteristics such as a large surface, flexibility, and molecule-recognition ability. Supramolecular 2D materials based on biological systems provide a novel perspective for the deve...

Polyoxometalates (POMs) are a family of anionic metal-oxo clusters, attracting much attention based on their unique structures and remarkable properties. POM is one type of widely used catalyst owing to their special features of excellent thermal stability, strong redox activity, and multi-electron transfer and storage properties. Cyclometalated units of Ru(N^N) 3 and Ir(C^N) 2 (N^N) have intriguing photo physicochemical properties, such as strong photo-absorption and long excited state lifetime, thus playing an important role in photocatalysis. In the past decade, the photocatalysis system incorporating Ru (Ir)-photosensitizers and POMs received rapid development. In this review, the coupled modes of Ru (Ir)-photosensitizer and POMs were classified into four categories, and the future development was prospected as well.
