BODIPY-Au(I): A Photosensitizer for Singlet Oxygen Generation and Photodynamic Therapy

Upon complexation with Au(I), a photoinactive BODIPY derivative was transformed into a highly photoactive triplet sensitizer. Along with high efficiency in singlet oxygen generation (φδ = 0.84), the new BODIPY-Au(I) skeleton showed excellent ph

Switching of the photophysical properties of bodipy-derived trans bis(tributylphosphine) Pt(ii) bisacetylide complexes with rhodamine as the acid-activatable unit

A rhodamine moiety was used for the preparation of trans bis(tributylphosphine) Pt(ii) bisacetylide complexes (RH-BDPY-Pt-1 and RH-BDPY-Pt-2, with two different Bodipy acetylide ligands), which show acid/base-switchable photophysical properties. The rhoda

A Ratiometric Fluorescent Probe for Gold and Mercury Ions

A fluorescent probe that displays a ratiometric fluorescence response towards gold and mercury ions has been devised. Emitting at a relatively longer wavelength, the conjugated form of the fluorescent dye transforms in the presence of the gold or mercury

Trans-Bis(alkylphosphine) platinum(ii)-alkynyl complexes showing broadband visible light absorption and long-lived triplet excited states

Heteroleptic trans-bis(alkylphosphine) platinum(ii) bisacetylide complexes Pt-1 and Pt-2 were prepared to achieve broadband absorption of visible light. Two different ethynylBodipy ligands, 2-ethynylBodipy and 2,6-diethynylBodipy or 8-(4′-ethynylphenyl)Bodipy, were used in each complex. Each Bodipy ligand gives strong absorption in the visible spectral region, but at different wavelengths, thus broadband absorption in the visible spectral region was achieved for the Pt(ii) complexes (ε is up to 1.85 × 105 M-1 cm-1 in the region of 450-700 nm). Singlet energy transfer from the peripheral coordinated Bodipy to the central coordinated Bodipy (with 2,6-diethynyl substitution) was confirmed by steady state absorption/luminescence spectroscopy, fluorescence excitation spectroscopy and nanosecond/femtosecond ultrafast time-resolved transient absorption spectroscopy. Long-lived triplet excited states were observed for both complexes (τT = 63.13 μs for Pt-1 and τT = 94.18 μs for Pt-2). Nanosecond time-resolved transient absorption spectroscopy indicated that the triplet excited state of Pt-1 is distributed on both Bodipy units. For Pt-2, however, the T1 state is confined to the central coordinated Bodipy ligand. These complexes show high singlet oxygen (1O2) quantum yields (ΦΔ = 76.0%). With nanosecond pulsed laser excitation, delayed fluorescence was observed for the complexes (τDF = 43.8 μs for Pt-1 and τDF = 111.0 μs for Pt-2), which is rarely reported for transition metal complexes. The complexes were used as efficient multi-wavelength excitable triplet photosensitizers for triplet-triplet annihilation upconversion. This journal is

Red-light-absorbing diimine Pt(ii) bisacetylide complexes showing near-IR phosphorescence and long-lived 3IL excited state of Bodipy for application in triplet-triplet annihilation upconversion

Bodipy is used for the preparation of Pt(ii) bisacetylide complexes which show strong absorption of visible light and long-lived triplet state. Room temperature (RT) near-IR phosphorescence of Bodipy was observed. The π-conjugation framework of visible li

Organic triplet sensitizer library derived from a single chromophore (BODIPY) with long-lived triplet excited state for triplet-triplet annihilation based upconversion

Triplet-triplet annihilation (TTA) based upconversions are attractive as a result of their readily tunable excitation/emission wavelength, low excitation power density, and high upconversion quantum yield. For TTA upconversion, triplet sensitizers and acceptors are combined to harvest the irradiation energy and to acquire emission at higher energy through triplet-triplet energy transfer (TTET) and TTA processes. Currently the triplet sensitizers are limited to the phosphorescent transition metal complexes, for which the tuning of UV-vis absorption and T1 excited state energy level is difficult. Herein for the first time we proposed a library of organic triplet sensitizers based on a single chromophore of boron-dipyrromethene (BODIPY). The organic sensitizers show intense UV-vis absorptions at 510-629 nm (ε up to 180,000 M-1 cm-1). Long-lived triplet excited state (τT up to 66.3 μs) is populated upon excitation of the sensitizers, proved by nanosecond time-resolved transient difference absorption spectra and DFT calculations. With perylene or 1-chloro-9,10-bis(phenylethynyl) anthracene (1CBPEA) as the triplet acceptors, significant upconversion (ΦUC up to 6.1%) was observed for solution samples and polymer films, and the anti-Stokes shift was up to 0.56 eV. Our results pave the way for the design of organic triplet sensitizers and their applications in photovoltaics and upconversions, etc.

Incorporating BODIPY fluorophores into tetrakis(arylethynyl)benzenes

Six structural isomers of a tetrakis(arylethynyl)benzene (TAEB) chromophore functionalized with dibutylamine and BODIPY moieties as the corresponding donor and acceptor units were prepared. To evaluate the effectiveness of the donor group, two TAEB molecules and three structurally related bis(arylethynyl)benzene (BAEB) isomers containing only acceptors were also synthesized. The electronic absorption and emission spectra of each series were examined. Additionally, computational studies were employed to corroborate the relative energy levels and gaps present in each series.
