Two decades after the rapid expansion of photovoltaics, number solar panels reaching end-of-life is increasing. While precious metals such as silver and copper are usually recycled, silicon, which makes up bulk a cells, goes to landfills. This due defect- impurity-sensitive nature in most silicon-based technologies, rendering it uneconomical purify waste silicon. Thermoelectrics represents rare class material defects impurities can be engineered enhance performance. because majority-carrier...
In this study, unique methyl-functionalized derivatives (T*PP+) of the drug carrier triphenylphosphonium (TPP+) that exhibit significant enhancement accumulation both cation and its conjugated cargo in cell mitochondria are designed. We show presence methyl group(s) at key positions within phenyl ring results an increase hydrophobicity solvent accessible surface area T*PP+. particular, when para position T*PP+ is functionalized with a group, most exposed to surrounding environment, leading...
The ability to rationally design and predictably construct crystalline solids has been the hallmark of crystal engineering research. To date, numerous examples multicomponent crystals comprising organic molecules have reported. However, cocrystals both inorganic chemical units is still poorly understood mostly unexplored. Here, we report a new diverse set higher-order (HOCs) based on structurally versatile-yet largely unexplored-phosph(V/V)azane heterosynthon building block. novel ternary...
Mechanochemistry is emerging as a powerful solvent-free approach to chemical synthesis, having been applied metal oxides, pharmaceutical materials, organic compounds and lesser extent, coordination complex synthesis. Notably, examples of applications mechanochemical methodologies in the synthesis main-group are few far between. Herein, we demonstrate that ball milling enabled range phosphazane frameworks with broad substrate scope, yielding seven new acyclic macrocyclic species. The strength...
Mechanochemistry has been established to be an environmentally-friendly way of conducting reactions in a solvent-free manner.
Mixed-dimensional perovskites containing mixtures of organic cations hold great promise to deliver highly stable and efficient solar cells. However, although a plethora relatively bulky have been reported for such purposes, fundamental understanding the materials' structure, composition, phase, along with their correlated effects on corresponding optoelectronic properties degradation mechanism remains elusive. Herein, we systematically engineer structures template low-dimensional contrasting...
The massive adoption of renewable energy especially photovoltaic (PVs) panels is expected to create a huge waste stream once they reach end-of-life (EoL). Despite having the highest embodied energy, present recycling neglects high purity silicon found in PV cell. Herein, scalable and low process developed recover pristine from EoL solar panel through method which avoids energy-intensive temperature processes. extracted was upcycled form lithium-ion battery anodes with performances comparable...
Chromium catalysts with diazaphospholane ligands have shown good activities and selectivities for ethylene tri- tetramerisation. Oligomerisations a doubly N-bridged cyclodiphosphazane result in Schulz–Flory distribution of α-olefins.
Herein we describe that oxidation reactions of the dimeric cyclophosphazanes, [{P(μ-NR)}2(μ-NR)]2, R = tBu (1), to produce a series diagonally dioxidized products P4(μ-NtBu)6E2 [E O (2), S (3), and Se (4)] tetraoxidized frameworks. The latter display an unexpected C–N bond activation cleavage novel phosphazane macrocyclic arrangements containing newly formed N–H bonds. Macromolecules P4(μ-NtBu)4(μ-NH)2O4 (5) P4(μ-NtBu)3(μ-NH)3E4, E (6) (7), dicleaved tricleaved products, respectively, are...
Bench-top stable <italic>cis</italic>-cyclodiphosph(<sc>v</sc>/<sc>v</sc>)azanes are demonstrated to form robust R21(8) bifurcated hydrogen-bonds and PSe⋯Br halogen bonds. This work highlights the potential of cyclodiphosph(<sc>v</sc>/<sc>v</sc>)azane building blocks in creating new supramolecular assemblies.
We have synthesized a completely new family of acyclic trimeric cyclodiphosphazane compounds comprising NH, Ni Pr, Nt Bu and NPh bridging groups. In addition, the first NH-bridged dimeric cyclophosphazane has been produced. The species display highly tuneable characteristics so that distance between terminal N(H)R moieties can be readily modulated by steric bulk present in groups (ranging from ≈6 to ≈10 Å). Moreover, these exhibit pronounced topological changes when weak non-bonding NH⋅⋅⋅π...
Inorganic macrocycles remain challenging synthetic targets due to the limited number of strategies reported for their syntheses. Among these species, large fully inorganic cyclodiphosphazane have been experimentally and theoretically highlighted as promising candidates supramolecular chemistry. In contrast, hybrid organic-inorganic counterparts are lagging behind lack routes capable controlling size topological arrangement (i.e., folded vs unfolded) target macrocycle, rendering synthesis...

Photovoltaic Waste In article number 2110518, Nripan Mathews, Jing Wu, Ady Suwardi and co-workers enable upcycling of waste photovoltaics into thermoelectrics, making use the majority-carrier nature which are generally more defect- impurity-tolerant than minority-carrier-based photovoltaics. This work helps to close loop circular economy for renewable energy.
The ability to rationally design and predictably construct crystalline solids has been the hallmark of crystal engineering research over past two decades. When building higher-order multicomponent cocrystals (i.e. crystals containing more than constituents), differential hierarchical way molecules interact assemble in solidstate is pinnacle importance. To date, numerous examples comprising organic leading salts, or ionic have reported. However, hybrid organicinorganic with sophisticated...
Herein, we report an unprecedented combination of pre-arranged building blocks and a multi-step synthetic route to rationally simultaneously enable access unfolded tetrameric macrocycle, which is not accessible using conventional strategies. The obtained cis-[μ-P(μ-NtBu)]2(μ-p-OC6H4C(O)O)]4[μ-P(μ-NtBu)]2 (4), the first open-face hybrid cyclodiphosphazane macrocycle reported displays cavity area 110.1 Å2 - largest its kind.<br>
