trans-A2B-corroles bearing -OCH2CONHR groups at the ortho position of the meso-phenyl substituent undergo self-organization both in the solid state as well as in solution. The lack of additional donor atoms induces sheet formation, but if the pyridine unit is present in the structure, more complex helical forms are formed.
The synthesis and photophysical properties of two multichromophoric systems, Pt(II)/B(III) and Pt(II)/Ir(III), based on novel N^O-julolidine ligands are reported. The functionalization of the julolidine core enables the introduction of two different anchoring sites, a terminal acetylene and an N^O chelating moiety, which allow the assembling of two… (More)
A novel class of luminescent octahedral ruthenium complexes 2-4 displaying a π-bonded quinonoid ligand is described. Remarkably, the presence of this organometallic ligand affects their UV-vis properties and transforms them into panchromatic absorbers. Furthermore, it turns on room temperature NIR emissions.
A unique class of neutral cyclometalated platinum(ii) complexes with π-bonded benzenedithiolate are reported including two X-ray molecular structures. To the best of our knowledge these are the first structures to be reported for cyclometalated platinum complexes with a benzenedithiolate ligand. All of the complexes are luminescent in fluid solution at room… (More)
Alkaline earth (group 2) metal ion organic frameworks (AEMOFs) represent an important subcategory of MOFs with interesting structures and physical properties. Five MOFs, namely, [Mg2(H2dhtp)2(μ-H2O)(NMP)4] (AEMOF-2), [Mg2(H2dhtp)1.5(DMAc)4]Cl·DMAc (AEMOF-3), [Ca(H2dhtp)(DMAc)2] (AEMOF-4), [Sr3(H2dhtp)3(DMAc)6]·H2O (AEMOF-5), and [Ba(H2dhtp)(DMAc)] (AEMOF-6)… (More)
The preparation and the photophysical behaviour of novel julolidine derivatives designed for displaying excited state intramolecular proton transfer (ESIPT) are reported. These dyes exhibit panchromatic photoluminescence covering the whole visible spectral range, both in organic solvents and in the solid state.
Here we report on the synthesis, characterization, and photophysics of multichromophoric arrays based on a triptycene scaffold that acts as a bridging ligand for Ir(III) and Os(II) satellite active components. The triptycene scaffold not only furnishes a rigid star-shaped 3D displacement of the metallic units in space but also plays an active role in the… (More)
This paper describes expeditious stepwise synthesis of polynuclear complexes based on heteroleptic iridium(iii) and osmium(ii) fragments linked to a central Pt(ii) module via a spirobifluorene-bridge using a strategy based on the construction of preformed complexes. The luminescence features of the final multi-chromophoric array, i.e. a tetrad consisting of… (More)
A series of bipyridyl (bpy) Pt(II) complexes with π-bonded catecholate (cat) [(bpy)Pt(LM)][BF4]n (2-5) (LM = Cp*Rh(cat), n = 2; Cp*Ir(cat), n = 2; Cp*Ru(cat), n = 1; and (C6H6)Ru(cat), n = 2) were prepared and fully characterized. The molecular structures of the four compounds were determined and showed that the solid-state packing is different and… (More)
We report the synthesis and luminescence properties of a novel platinum(ii)-silver(i) cluster exhibiting supramolecular donor-acceptor dative Pt → Ag bonds as well as d(10)...d(10) argentophilic interactions. This compound was obtained by a self-assembly process upon mixing silver triflate with the [Pt(bdt)(bpy)] (1) building block. The new compound was… (More)
