We have structurally and magnetically characterized a total of 12 complexes based on the Single-Molecule Magnet (SMM) [MnIII6O2(sao)6(O2CH)2(MeOH) 4] (1) (where sao2- is dianion salicylaldoxime or 2-hydroxybenzaldeyhyde oxime) that display analogous structural cores but remarkably different magnetic behaviors. Via use derivatized oxime ligands bulky carboxylates we show it possible to deliberately increase value spin ground state [Mn6O2(Me-sao)6(O2CCPh3)2(EtOH)4] (2),...
Abstract Although all‐inorganic perovskite solar cells (PSCs) demonstrate high thermal stability, cesium‐lead halide perovskites with iodine content suffer from poor stability of the black phase (α‐phase). In this study, it is demonstrated that incorporating InCl 3 into host lattice helps to inhibit formation yellow (δ‐phase) and thereby enhances long‐term ambient stability. The enhanced achieved by a strategy for structural reconstruction CsPbI 2 Br means 3+ Cl − codoping, which gives rise...
The synthesis and characterisation of a large family hexametallic [Mn(III)(6)] Single-Molecule Magnets general formula [Mn(III)(6)O(2)(R-sao)(6)(X)(2)(sol)(4-6)] (where R = H, Me, Et; X (-)O(2)CR' (R' Ph etc) or Hal(-); sol EtOH, MeOH and/or H(2)O) are presented. We show how deliberate structural distortions the [Mn(3)O] trinuclear moieties within [Mn(6)] complexes used to tune their magnetic properties. These findings highlight qualitative magneto-structural correlation whereby type (anti-...
This article takes a broad view of the understanding magnetic bistability and quantum tunneling in single-molecule magnets (SMMs), focusing on three families relatively simple, low-nuclearity transition metal clusters: spin S = 4 Ni4, Mn(III)3 (S 2 6) Mn(III)6 12). The Mn(III) complexes are related by fact that they contain triangular Mn3 units which exchange may be switched from antiferromagnetic to ferromagnetic without significantly altering coordination around centers, thereby leaving...
Trigonal selenium (t-Se) is a promising wide-band-gap photovoltaic material with high absorption coefficient, abundant resources, simple composition, nontoxicity, and low melting point, making it suitable for absorbers in advanced indoor tandem applications. However, severe electrical losses at the rear interface of t-Se absorber, caused by work function lattice mismatches, limit voltage output overall performance. In this study, strategy to enhance carrier transport collection modifying...
Inventing the double wheel: A mixed–valent [Mn32] cluster with a very rare "double-decker" wheel topology (see its metal–oxygen core: MnIII blue, MnII pink, O red) is reported. It by far highest-nuclearity example of type, and it displays SMM behavior largest effective barrier to magnetization relaxation (Ueff≈44.5 K) for any molecular wheel. Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset....
The use of derivatised salicylaldoximes in manganese chemistry has led to the synthesis a family approximately fifty hexanuclear ([Mn(III)(6)]) and thirty trinuclear ([Mn(III)(3)]) Single-Molecule Magnets (SMMs). Deliberate, targeted structural distortion metallic core afforded members with increasingly puckered configurations, leading switch pairwise magnetic exchange from antiferromagnetic ferromagnetic. Examination both data revealed semi-quantitative magneto-structural correlation, which...

A biased spin doctor: Structural distortions change the intramolecular exchange from antiferromagnetic to ferromagnetic, producing a range of 3D networks [MnIII3] exchange-coupled single-molecule magnets (SMMs, 1–6), which demonstrate that quantum tunnelling magnetisation (QTM) can be controlled using interactions. This opens up new perspectives in use supramolecular chemistry modulate physics molecular nanomagnets.
The first 3d-4f clusters built using derivatised salicylaldoximes (R-saoH(2)) describe unusual hexagonal prisms. Replacement of the paramagnetic Gd(III) ions with diamagnetic Ln(III) allows for a more thorough understanding magnetic properties, whilst replacement Tb(III) doubles U(eff).
