During the past decade, it has been shown that light-matter strong coupling of materials can lead to modified and often improved properties which stimulated considerable interest. While charge transport be enhanced in n-type organic semiconductors by electronic transition thereby splitting conduction band into polaritonic states, is not clear whether same process also influence carrier valence p-type semiconductors. Here we demonstrate indeed possible enhance both conductivity...
Hysteresis and energy barrier of a phase transition are shown to be significantly modified by strong coupling (red curves).
Abstract A non‐interpenetrated metal–organic framework with a paddle‐wheel secondary building unit has been activated by direct thermal evacuation, guest exchange volatile solvent, and supercritical CO 2 drying. Conventional activation yields mixture of crystalline phases some amorphous content. Exchange solvent prior to vacuum produces pure breathing phase high sorption capacity, selectivity for over N CH 4 , substantial hysteresis. Supercritical drying can be used access guest‐free open...
Two one-step-synthesized ligands, one chiral and emissive, assemble with Pd II into a heteroleptic cage that shows enhanced CPL.
The self-assembly between a bis-monodentate tecton based on two pyridine units connected to an enantiomerically pure isomannide stereoisomer and HgCl2 leads the formation of triple stranded helical infinite coordination network which was structurally characterised by X-ray diffraction single crystal.
A series of emitters displaying efficient photoluminescence (PL) and electroluminescence (EL) into the true- to sky-blue regions is herein described employed as electroluminescent materials for fabrication blue organic light-emitting diodes (OLEDs). The compounds possess linear, yet a twisted, donor−π–acceptor−π–donor (D−π–A−π–D) architecture, where D are (substituted) carbazole (Cz) thiazolo[5,4-d]thiazole (TzTz) moiety electron donor accepting unit, respectively. = 9H-carbazol-9-yl...
Abstract Optoelectronic devices that emit into the near infrared (NIR) region are appealing technologies with applications in optical communication and as disposable, lightweight cheaper photodynamic biomedical devices. The development of efficient is currently hampered by lack suitable NIR‐emissive materials. Achieving this goal even more challenging when use non‐toxic, earth‐abundant metal complexes electroactive materials targeted. Herein, an enlarge family binuclear Cu(I) emitters ( D1 –...
Two new coordination polymers (1 (2D) and 2 (3D)), based on the use of a V-shaped ligand L (9,9-bis(4-carboxyphenyl)fluorene) combined with Cu(NO 3 ) or Zn(NO , were synthesized structurally characterized by single-crystal X-ray diffraction.
Copper(I) complexes have attracted considerable attention as efficient redox photocatalysts (PCs) in photopolymerization. In this study, two copper(I) bearing a pyridine-benzothiazole ligand were thoroughly investigated for the free radical photopolymerization of ethoxylated trimethylolpropane triacrylate under violet and green light irradiation. A three-component system comprising copper complex, di-tert-butyl-diphenyl iodonium hexafluorophosphate, ethyl dimethylaminobenzoate additives was...
Upon crystallisation of two bismonodentate tectons based on pyridine units, interconnected at the meta position by a tetra- or hexa-ethylene glycol fragment and Ag+ cation, double stranded helical infinite coordination networks were formed structurally characterised. The cationic architectures obtained may be regarded as analogues DNA in terms topology.

Using CoCl2 and a chiral tecton possessing C2 chirality based on two coordination poles composed of pyridine unit connected at the 4-position to bearing 2 6 positions optically active oxazoline moieties, polar solid is obtained. The latter results from acentric packing directional 1-D networks.
Two binuclear heteroleptic CuI complexes, namely Cu-NIR1 and Cu-NIR2, bearing rigid chelating diphosphines π-conjugated 2,5-di(pyridin-2-yl)thiazolo[5,4-d]thiazole as the bis-bidentate ligand are presented. The proposed dinuclearization strategy yields a large bathochromic shift of emission when compared to mononuclear counterparts (M1-M2) enables shifting luminescence into near-infrared (NIR) region in both solution solid state, showing maximum at ca. 750 712 nm, respectively. radiative...
The role played by different anions (XF6− (X = P, As, Sb), BF4−) on the connectivity of coordination networks formed a combination silver salts and an organic tecton based piperazine bearing two pyridine units has been studied in crystalline phase X-ray diffraction single crystal. All four weakly coordinating lead to formation analogous 2-D networks. For isostructural XF6− Sb) crystals are isomorphous.

The pore size and shape of cuboid 3-D coordination networks may be modulated by combining rigid neutral organic tectons different length bearing two pyridines oriented in a divergent fashion with zinc dication SiF6 dianion behaving as metallic node an inorganic tecton, respectively.
Supramolecular arrays composed of 1-D coordination networks on surfaces, with nanoscale control over both the geometry and directionality, are achieved through design combination organic tectons metal complexes (CoCl2) or centers (Pd(BF4)2). Scanning tunneling microscope at solid/liquid interface allows visualization long shape-persistent arrays, either linear zig-zag geometries.
