A Mobil Composition of Matter (MCM)-41 type mesoporous silica material containing N-propylacridone groups has been successfully prepared by co-condensation of an appropriate organic precursor with tetraethyl orthosilicate (TEOS) under alkaline sol-gel conditions. The resulting material was fully characterized by means of X-ray diffraction (XRD),(More)
Dithienylated phenothiazines (DTPTs) with different functional groups attached to the central nitrogen atom are presented as a class of versatile metal-free chromophores for the design of dye-sensitized solar cells (DSSCs) and organic light-emitting diodes (OLEDs). The electronic characteristics of spin-coated thin films on polycrystalline gold were studied(More)
The present study focused on genotoxic properties of the carcinogenic phenylpropanoids α-asarone and β-asarone, which are found in several herbs and spices, such as Acorus calamus or Acorus gramineus. Cytotoxic and genotoxic effects were determined in human liver carinoma HepG2 cells, in hamster lung fibroblast V79 cells and in human cytochrome P450 1A2 and(More)
Three highly fluorescent phosphonates have been prepared in good yields from different arylene bridged 5-iodothiophenes by following an optimized four-step procedure. The compounds have been immobilised on mesoporous zirconia, alumina and titania particles in order to probe their luminescence properties on the surfaces. The organic compounds as well as the(More)
