Owing to high interfacial conductivity, organic heterostructures hold great promises augment the electrical performances of electronic devices. In this endeavor, present work reports fabrication novel polyporphine/phthalocyanine and investigates modulation charge transport induced by structural change polyporphine its implication on ammonia sensing properties. Polyporphines materials are electr...

The photosensitization of microorganisms is potentially useful for sterilization and for the treatment of certain bacterial diseases. Until now, any broad spectrum approach has been inhibited because, although Gram-positive bacteria can be photoinactivated by a range of photosensitizers, Gram-negative bacteria have not usually been susceptible to photosensitized destruction. In the present work...

We have demonstrated that the external quantum efficiency (EQE) of organic photovoltaic cells with a heterojunction zinc phthalocyanine (ZnPc) and fullerene (C60) bilayer films, which are used as donor an acceptor, respectively, is improved by photopolymerization (photon energy: 2–4 eV light fluence: 0.4 W cm−2) between adjacent C60 molecules via [2 + 2] cycloadditional four-membered ring. Comp...

A mathematical model is proposed for calculating the ionization potentials of molecules on surface dielectrics in order to quantify changes electronic characteristics materials a substrate. The semiconductor and photoelectronic properties nanosystems based phthalocyanine derivatives are determined by structure molecules. Based zinc phthalocyaninate molecule ZnC32N8H16, structures constructed th...

In vitro and in vivo studies were undertaken utilizing an established rat glioma cell line (C6) to compare the phototoxicity characteristics of aluminium tetrasulfonated phthalocyanine (AlSPc), zinc tetrasulfonated phthalocyanine (ZnSPc) and haematoporphyrin derivative (HpD). AlSPc and ZnSPc were inherently less cytotoxic in the dark compared to HpD with 50% colony survival at 275, 355 and 14 m...
