<p>The sensitivity of a QCM-based VOCs sensor with two kinds metal phthalocyanine, i.e., copper phthalocyanine (CuPc) and zinc (ZnPc) was examined for various VOCs. The the determined by compatibility overlapped orbitals (Cu(II) dan Zn(II)) corresponding CuPc ZnPc layer were deposited on quartz crystal oscillator vacuum evaporation method. frequency shift sensors functional layers tested ...

Asymmetric zinc phthalocyanines with alkyl chain substituents formed highly efficient light-harvesting layers on a TiO2 surface. Dye-sensitized solar cells using PcS20 exhibited a record efficiency of 6.4% under one-sun irradiation.

Organic solar cells based on a series of water-soluble zinc phthalocyanines (wsZnPc) with varying numbers of sulfonate peripheral substituents and a C60 donor have been fabricated and characterised. We find that the number of substituents affects both the V(oc) and J(sc) of the devices, with the disulfonated wsZnPc devices performing best.

Panchromatic response is essential to increase the light-harvesting efficiency in solar conversion systems. Herein we show increased light harvesting from using multiple energy relay dyes inside dye-sensitized solar cells. Additional photoresponse from 400-590 nm matching the optical window of the zinc phthalocyanine sensitizer was observed due to Förster resonance energy transfer (FRET) from t...

We disclose herein the perfluoroalkylation of alkenes catalyzed by trifluoroethoxy-coated zinc phthalocyanine under irradiation of visible light. Perfluoroalkyl iodides were nicely incorporated into unsaturated substrates, including alkyne, to provide perfluoroalkyl and iodide adducts in moderate to good yields. Trifluoromethylation is also possible by trifluoromethyl iodide under the same reac...

Photoexcitation of a zinc phthalocyanine-perylenediimide (ZnPc-PDI) dyad affords the triplet excited state without the fluorescence emission, whereas addition of Mg2+ to the photoexcited ZnPc-PDI results in formation of a long-lived charge-separated state (ZnPc.+-PDI.-/Mg2+) in which PDI.- forms a complex with Mg2+.

The aim of the present study was to evaluate the photodynamic efficacy of a novel phthalocyanine derivate 2,3,9,10,16,17,23,24-octakis[(N,N-dimethylamino) ethylsulfanyl]phthalocyaninatozinc(II) (referred here as S1) using MCF-7c3 human breast cancer cells and the LM2 adenocarcinoma subcutaneously implanted in Balb/c mice as experimental models. The S1-l-alpha-dimyristoyl-phosphatidylcholine lip...

The photophysical properties of zinc phthalocyanine (ZnPC) and chloroaluminum phthalocyanine (AlPHCl) incorporated into liposomes of dimyristoyl phosphatidylcholine in the presence and absence of additives such as cholesterol or cardiolipin were studied by time-resolved fluorescence, laser flash photolysis and steady-state techniques. The absorbance of the drugs changed linearly with drug conce...

A novel supramolecular triad composed of a zinc porphyrin-zinc phthalocyanine dyad and fullerenes has been assembled using a 'two-point' axial binding approach, and occurrence of efficient photoinduced energy transfer followed by electron transfer is demonstrated.

Density functional theory (DFT) simulations were used to determine the binding strength of 12 electron-donating analytes to the zinc metal center of a zinc phthalocyanine molecule (ZnPc monomer). The analyte binding strengths were compared to the analytes' enthalpies of complex formation with boron trifluoride (BF(3)), which is a direct measure of their electron donating ability or Lewis basici...
