“…In the soft‐templating method the mesopore arrangement is achieved by employing soft‐matter supramolecular aggregates such as amphiphilic surfactant molecules or block copolymers, which can co‐assemble with inorganic (or organic) guest species 98,99 . Owing to their intrinsic amphiphilic nature and hydrophobic effect, such amphiphilic molecules self‐assemble into micellar structures constituted by a hydrophobic (nonpolar) core and an outer rim (shell) of polar groups, when dispersed in a polar medium (e.g., water or ethanol).…”

“…The interactions between the organic template molecules and guest species are considered the most important driving forces for obtaining ordered templated mesophases. These interactions mainly include weak noncovalent bonds, such as hydrogen bonds and Van der Waals or electrostatic interactions 97–99,102–104 . Eventually, upon the removal of the organic template by calcination, pyrolysis, ion‐exchange, or solvent extraction, the final ordered mesoporous material (with open pores) can be obtained with a pore structure that resembles the structure of the liquid‐crystal mesophase.…”

Porous metal chalcogenides have emerged as promising materials for environmental remediation and sustainable energy generation. Their tunable optical band gap (from infrared to the visible range), highly polarizable surface, chemical activity, and adjustable structure make them attractive for various applications. This review summarizes the recent developments concerning the synthesis and characterization of multifunctional porous chalcogenide materials. It explores their remarkable potential in addressing environmental and energy challenges. Moreover, we discuss the several factors that affect the performance of porous metal chalcogenides, such as their microstructure, morphology, and chemical composition, to gain deeper insights into these materials. Finally, we highlight some of the key challenges and future research directions in the development of porous metal chalcogenides as effective and efficient materials for environmental remediation and sustainable energy generation.image

Amphiphilic block copolymers comprise a fascinating class of smart materials due to their unique ability to selforganize, making them attractive candidates for a wide range of applications in materials engineering and medical sciences. The synthesis of these copolymers commonly involves harmful solvents, especially in classical living anionic polymerization. With the development of reversible addition−fragmentation chain transfer (RAFT) and polymerization−induced self-assembly (PISA), an environmentally more friendly and versatile method has been established for the synthesis of such amphiphilic block copolymers. Through the utilization of visible light to initiate polymerization through the so-called photoiniferter process, we emphasize the adaptability of this photopolymerization in different scales although the incident light illuminates only the surface area of the reaction vessels. We describe an easily adjustable, blue-lightinitiated RAFT PISA approach to synthesize a series of amphiphilic poly(N,N-dimethylacrylamide)−block−polystyrene (PDMA−b− PS) and poly(4-vinylpyridine)−block−polystyrene (P4VP−b−PS) diblock copolymers with low molecular weight dispersities. The polymerizations were conducted as both two-step and semibatch processes. Furthermore, the effect of scalability on the polymerization kinetics was investigated, proving the light-induced RAFT polymerization as a scalable polymerization method in a batch process with a reaction volume of up to 500 mL. The bulk morphology of both resulting diblock copolymers having different weight fractions of the minor and major blocks was analyzed. While a cylindrical PDMA microdomain in a PS matrix can be observed at 20−25% by weight of PDMA, the equivalent composition reveals a spherical morphology of P4VP domains in a PS matrix. In essence, the scalable, rather eco-friendly photoinduced synthesis of tailored, nanostructured block copolymers without harmful solvents significantly increases their suitability for applications.
