A lysosome-specific near-infrared fluorescent probe for: In vitro cancer cell detection and non-invasive in vivo imaging

Near-infrared (NIR) fluorescent probes have been developed as potential bio-materials having profound applications in diagnosis and clinical practice. Herein, we wish to disclose a highly photostable ultra-bright NIR probe for the specific detection of lysosomes in numerous cell lines. Furthermore, the applicability of the developed NIR probe was evaluated for in vivo imaging.

A Water-Soluble, NIR-Absorbing Quaterrylenediimide Chromophore for Photoacoustic Imaging and Efficient Photothermal Cancer Therapy

Precision phototheranostics, including photoacoustic imaging and photothermal therapy, requires stable photothermal agents. Developing such agents with high stability and high photothermal conversion efficiency (PTCE) remains a considerable challenge. Her

Viable access to the triplet excited state in peryleneimide based palladium complex §

Abstract: Triplet excited state in organic chromophores is ubiquitously significant owing to its utility in light harvesting and photovoltaic device applications. Herein, we report the enhancement in the triplet character of an innately triplet deficient peryleneimide chromophore via incorporation of a heavy atom. Palladium incorporated perylenemonoimide (PMI-Pd) was synthesized via oxidative addition of PMI-Br into Pd(0) under inert experimental conditions. The structural sanctity of the PMI-Pd and the model derivative PMI was characterized via single crystal X-ray diffraction and the close-packing was examined employing Hirshfeld surface analysis. The steady-state spectroscopic measurements of PMI-Pd in chloroform reveal an apparent perturbation in the UV-Vis absorption, fluorescence emission and lifetime characteristics. A much higher perturbation is observed in the ultrafast photoexcited processes of PMI-Pd in chloroform as envisaged via nanosecond transient absorption (nTA) measurements. The nTA measurements of PMI-Pd in chloroform reveal a significant enhancement in the triplet character of PMI-Pd as compared to the model derivative PMI. Spin-orbit coupling (SOC) mediated triplet enhancement in PMI-Pd suggest heavy atom incorporation as a viable route for accessing the triplet excited states in triplet deficient aromatic chromophores. SOC mediated triplet enhancement in innately triplet deficient organic chromophores can revive the utility of these materials for novel photovoltaic and energy storage applications. Graphical abstract: SYNOPSIS Synthesis and characterization of a perylenemonoimide palladium(II) complex (PMI-Pd) and the enhancement in the triplet excited state of PMI-Pd as compared to PMI are explored. The results suggest that the combined spin-orbit coupling mediated by the incorporation of palladium and bromine atoms results in the enhancement of the triplet character in PMI-Pd.

Synthesis of an Acceptor-Donor-Acceptor Multichromophore Consisting of Terrylene and Perylene Diimides for Multistep Energy Transfer Studies

Motivated by the results obtained from the investigation of singlet-singlet annihilation in a linear multichromophore comprising terrylene diimides (TDI) and perylene diimide (PDI) in 2010, we report the detailed process toward the successful synthesis of a TDI-PDI-TDI dyad. Ineffective synthetic pathways, which were necessary for the understanding of the step-by-step construction of the complex multichromophore, are described, leading toward a universal synthetic plan for multicomponent systems containing rylene diimides separated by rigid oligophenylene spacers.

Photo-initiated multi-step electron transfer in donor-acceptor systems using a novel bi-functionalized perylene chromophore

tThe excited state and redox properties of a new bi-functional perylene redox chromophore, 2,3-dihydro-1-azabenzo[cd]perylene (DABP), are described. Perylene has been widely used in electron donor-acceptormolecules in fields ranging from artificial photosynthesis to molecular spintronics. However, attachingmultiple redox components to perylene to carry out multi-step electron transfer reactions often produceshard to separate regioisomers, which complicate data analysis. The use of DABP provides a strategy toretain the electronic properties of perylene, yet eliminate regioisomers. Ultrafast photo-initiated single-and two-step electron transfer reactions in three linear electron donor-acceptor systems incorporatingDABP are described to illustrate its utility.

New soluble near-infrared dyes based on terrylene diimides with four aromatic heterocycles

Terrylene diimides with four aromatic heterocycles (AHTDIs) were synthesized under Stille Cross-coupling conditions and fully characterized by NMR and mass spectrometry. The aggregation of the terrylene diimide (TDI) was suppressed by four heterocycles substituents on the bay region, and these AHTDIs exhibited good solubility in common organic solvents. The effects of the substituted groups on the optical and electrochemical properties were also investigated. The introduction of four aromatic heterocycles on the bay of TDI resulted in significant red-shifts of the absorption peak (100 nm), corresponding to a decrease in the band gap from 1.82 to 1.50 eV. Furthermore, with four rich electron aromatic heterocycles, the AHTDIs showed 280 mV negative-shifts of first oxidation potentials and a new oxidation wave, corresponding to an increase in the HOMO levels from?-5.60 to?-5.28 eV. Two soluble NIR dyes based on terrylene diimides were synthesized by the introduction of aromatic heterocycles substituents on the bay region. The effects of the substituted groups on the optical and electrochemical properties were further investigated. Copyright

Photocontrolled intramolecular charge/energy transfer and fluorescence switching of tetraphenylethene-dithienylethene-perylenemonoimide triad with donor-bridge-acceptor structure

Photochromic 1,2-dithienylethene (DTE) derivatives with a high thermal stability and fatigue resistance are appealing for optical switching of fluorescence. Here, we introduce a donor-photochromic bridge-acceptor tetraphenylethene-dithienylethene-perylenemonoimide (TPE-DTE-PMI) triad, in which TPE acts as the electron donor, PMI as the electron acceptor, and DTE as the photochromic bridge. In this system, the localized and intramolecular charge transfer emission of TPE-DTE-PMI with various Stokes shifts have been observed due to the photoinduced intramolecular charge transfer in different solvents. Upon UV irradiation, the fluorescence quenching resulting from photochromic fluorescence resonance energy transfer in TPE-DTE-PMI has been demonstrated in solution and in solid films. The fluorescence on/off switching ratio in polymethylacrylate film exceeds 100, a value much higher than in polymethylmethacrylate film, thus indicating that the fluorescence switching is dependent on matrices.

Design, synthesis and photoswitching of broad-spectrum fluorescent hexaarylbiimidazoles

A series of novel hexaarylbiimidazole (HABI)-containing fluorophores with broad-spectrum emissions ranging from blue, green and red emissions, have been designed and synthesized. Their photochromism and fluorescence switching properties are investigated by UV-Vis absorption and fluorescence spectra in solutions and PMMA films. By connecting carbazole (Cz), naphthalimide (NI) and perylene-mono-imide (PMI) to HABI with a spacer, three molecular photoswitches with broad-spectrum fluorescence varying from deep blue (Cz-O-HABI, λem = 390 nm, ΦF = 0.27), green (NI-O-HABI, λem = 490 nm, ΦF = 0.25) to far red (PMI-O-HABI, λem = 650 nm, ΦF = 0.25) have been obtained. The "ON"/"OFF" ratios are calculated to be about 8.9, 8.0 and 3.7 (calculated from FL spectra) for Cz-O-HABI, NI-O-HABI and PMI-O-HABI, respectively. Such a series of photoswitchable fluorophores constitute prototypes of a photochromic molecular library in which fluorescence resonance energy transfer can be reversibly modulated by an external stimulus, namely, UV light.
