The use of fluorescent labels is the most common tool to visualize cells. However, internalization dye molecules often modifies cell behavior. In this paper we demonstrate that it possible transiently label cells using a 3D scaffold, hydrogel, covalently functionalized with luminescent cyclometalated iridium(III) complexes. unique feature our design complexes are emissive only when they interact membrane while their emission quenched in water. We exploited perform real-time and staining-free...
Two series of Pt(II)-cyclometallated compounds containing N^C^N tridentate and alkynyl-chromophore ligands have been synthesized structurally characterized. The differ on the presence R1 = H or F in central aromatic ring, while six different chromophores introduced to alkynyl moiety. Single-crystal X-ray structures for some reveal weak intermolecular contacts responsible formation dimers aggregates. photophysical characterization shows two emission bands solution assigned 3π-π* transition...
We report the synthesis of a luminescent Pt(II) complex, PtL 2 , based on "two-wall" aryl-extended calix[4]pyrrole (C[4]P). characterize its binding properties as receptor methyl trioctyl ammonium chloride (MTOA·Cl) in dichloromethane solution. To this end, we performed 1H NMR and UV-vis spectroscopic titrations. The singular allowed use highly sensitive emission spectroscopy to monitor binding. affinity for MTOA·Cl is 2-fold smaller than that C[4]P precursor. This difference attributed...
The synthesis of five novel cyclometalated platinum(II) compounds containing different alkynyl-chromophores was achieved by the reaction previously synthesized Pt-Cl compound (1) with corresponding RC≡CH a Sonogashira reaction. It observed that spectral and photophysical characteristics complexes (Pt-Ar) are essentially associated platinum-cyclometalated unit. Room-temperature emission Pt-Ar attributed to phosphorescence in agreement DFT calculations. Broad nanosecond (ns)-transient...
Platinum-based chemotherapy persists to be the only effective therapeutic option against a wide variety of tumours. Nevertheless, acquisition platinum resistance is utterly common, ultimately cornering conventional drugs palliative in many patients. Thus, encountering alternatives that are both and non-cross-resistant urgent. In this work, we report synthesis, reduction studies, luminescent properties series cyclometallated (C,N,N')PtIV compounds derived from amine-imine ligands, their...
Abstract Three series of metal salophen complexes derived from Zn 2+ , Cu Pt and Ni have been synthesized their interaction with quadruplex DNA has evaluated. The compounds differ on the number ethyl piperidine substituents. They characterized by 1 H NMR, IR UV‐visible spectroscopies HR‐mass spectrometry. Their luminescent properties also evaluated we can observe that, as expected, are those displaying more interesting luminescence an emission band red‐shifted respect to corresponding...
New [C,N,N′]-cyclometallated platinum(<sc>ii</sc>) and platinum(<sc>iv</sc>) complexes are prepared their emission properties reported.
The synthesis of three novel [C,N,N'] Pt(IV) cyclometallated compounds containing hydroxo, dichloroacetato or trifluoroacetato axial ligands is reported. Compound [PtCl(OH)
Luminescence studies performed on Ln( iii ) compounds with the formula [Ln 2 (μ -2FBz) 4 (2FBz) (H-2FBz) (H O) ] for Ln = Eu (1) and Tb (2) indicate improved luminescence emission.
Abstract Room temperature phosphorescence characteristics on filter paper of dibenzofuran (DF) and several polychlorinated dibenzofurans (PCDFs) in the presence different heavy atoms conjunction with a surface active agent, sodium lauryl sulfate (NaLS), have been studied. The use this surfactant produces an enhancement intensity all cases studied, which improve sensitivity determination DF PCDFs. optimization experimental conditions like type paper, drying cooling times after spotting...
