The polymorphism of phosphorus-based materials has garnered much research interest, and the variable chemical bonding structures give rise to a variety of micro and nanostructures. Among the different types of materials containing phosphorus, elemental phosphorus materials (EPMs) constitute the foundation for the synthesis of related compounds. EPMs are experiencing a renaissance in the post-graphene era, thanks to recent advancements in the scaling-down of black phosphorus, amorphous red phosphorus, violet phosphorus, and fibrous phosphorus and consequently, diverse classes of low-dimensional sheets, ribbons, and dots of EPMs with intriguing properties have been produced. The nanostructured EPMs featuring tunable bandgaps, moderate carrier mobility, and excellent optical absorption have shown great potential in energy conversion, energy storage, and environmental remediation. It is thus important to have a good understanding of the differences and interrelationships among diverse EPMs, their intrinsic physical and chemical properties, the synthesis of specific structures, and the selection of suitable nanostructures of EPMs for particular applications. In this comprehensive review, we aim to provide an in-depth analysis and discussion of the fundamental physicochemical properties, synthesis, and applications of EPMs in the areas of energy conversion, energy storage, and environmental remediation. Our evaluations are based on recent literature on well-established phosphorus allotropes and theoretical predictions of new EPMs. The objective of this review is to enhance our comprehension of the characteristics of EPMs, keep abreast of recent advances, and provide guidance for future research of EPMs in the fields of chemistry and materials science.

Starfish-Inspired Diamond-Structured Calcite Single Crystals from a Bottom-up Approach as Mechanical Metamaterials

Hassan Sadek, Suhail K. Siddique, Chi-Wei Wang, Po-Ting Chiu, Chang-Chun Lee, and Rong-Ming Ho

Inspired by knobby starfish, this work demonstrates a bottom-up approach for fabricating a calcite single-crystal (CSC) with a diamond structure by exploiting the self-assembly of the block copolymer and corresponding templated synthesis. Similar to the knobby starfish, the diamond structure of the CSC gives rise to a brittle-to-ductile transition. Most interestingly, the diamond-structured CSC fabricated exhibits exceptional specific energy absorption and strength with lightweight character superior to natural materials and artificial counterparts from a top-down approach due to the nanosized effect. This approach provides the feasibility for creating mechanical metamaterials with the combined effects of the topology and nanosize on the mechanical performance.

Coordination-Promoted Bio-Catechol Electro-Reforming toward Sustainable Polymer Production

Ran Wang, Chong Li, Jianxiang Wu, Wei Du, Tao Jiang, Yizhou Yang, Xuejing Yang, and Ming Gong

Sustainable polymer production is essential for a carbon-neutral society. cis,cis-Muconic acid is attracting growing interest as a biomass-derived platform molecule with direct access to adipic acid and terephthalic acid, prominent monomers of commercial polymers. Here, a sustainable route of electro-reforming biorenewable catechol to cis,cis-muconic acid with concurrent H2 production has been proposed. By using a CuO foam electrode, a high cis,cis-muconate yield of 90% and a high faradaic efficiency of 87% can be achieved under ambient conditions without external oxidant. Zn2+ coordination with the catechol is central to the yield and selectivity. In a combinatory analysis via steady-state electrochemical kinetics, in situ spectroscopy, and theoretical calculation, we revealed that the reaction ensemble of catechol electrooxidation involves three major processes of polymerization, ring cleavage, and depolymerization, in which Zn2+ coordination is highly effective in delaying polymerization and promoting ring cleavage toward cis,cis-muconate. The catecholate coordinated to the Zn2+ cations reallocated its electron density with partial structural deformation to accelerate the electron transfer and facilitate the OH– nucleophilic attack. A practical two-electrode system was eventually demonstrated to efficiently and stably electro-reform catechol into isolable cis,cis-muconic acid and hydrogen, providing solutions for polymer sustainability via utilizing alternative biomass resources and electrified processes.

Two-Step Synthesis of B2N2-Doped Polycyclic Aromatic Hydrocarbon Containing Pentagonal and Heptagonal Rings with Long-Lived Delayed Fluorescence

Huan Luo, Qingyun Wan, Wookjin Choi, Yusuke Tsutsui, Evgenia Dmitrieva, Lili Du, David Lee Phillips, Shu Seki, Junzhi Liu

Polycyclic Aromatic Hydrocarbons
A pentagon-heptagon-embedded polycyclic aromatic hydrocarbon (PAH) consisting of B-N heteroatoms (BN-2) is synthesized in only two steps. Combining spectroscopic measurements and theoretical calculations, the excited-state dynamics of the resultant BN-doped PAHs are well-investigated, demonstrating both prompt fluorescence and long-lived delayed fluorescence components with their triplet excited-state lifetimes in the microsecond time region. More details can be found in article number 2301769 by Shu Seki, Junzhi Liu, and co-workers.
