Metal phthalocyanines can be very efficient as catalysts and photocatalysts in oxidation reactions using molecular oxygen oxidant. Different types of soluble low weight or oligomeric insoluble heterogeneous were developed. The metal exist either impregnated on SiO 2 , Al O 3 charcoal TiO covalently coordinatively bound organic polymers ionically an ion exchanger. catalytic oxidations toxic sulfide thiol derivative are studied. In addition, phenols employed substrates for the photooxidation....
Novel dyes based on the phenothiazine system D/A–π–D–π–A exhibit that elongation of π-conjugation is advantageous in design efficient photosensitizers.
New D-π-D-π-A low-molecular-weight compounds, based on a phenothiazine scaffold linked via an acetylene unit with various donor moiety and cyanoacrylic acid anchoring groups, respectively, were successfully synthesized. The prepared dyes entirely characterized using nuclear magnetic resonance (NMR) spectroscopy elemental analysis. compounds designed to study the relationship between end-capping groups' structure their optoelectronic thermal properties as well dye-sensitized solar cells'...
Novel symmetrical anthracene derivatives with bulky carbazolyl‐fluorene, diphenylamino‐fluorene, or carbazolyl‐carbazole units connected to the frame through an ethynyl bridge were synthesized in excellent yield by using Sonogashira cross‐coupling. The dyes increases π‐electron conjugation and substituents considerably attenuate intermolecular interactions. possess high thermal stability, tremendous solubility common organic solvents, especially photoluminescence quantum ( Φ f ) solution...
A series of novel styrylquinolines with the benzylidene imine moiety were synthesized and spectroscopically characterized for their applicability in cellular staining. The spectroscopic study revealed absorption ultraviolet–visible region (360–380 nm) emission that covered blue-green range light (above 500 nm). fluorescence quantum yields also determined, which amounted to 0.079 best-case scenario. structural features are behind these values discussed. An analysis properties theoretical...
The impact of the thickness TiO2 blocking layer (50, 150 and 300 nm) on DSSC performance based a new D-D-π-A architecture metal-free organic dyes commercial N719 was investigated. layers were prepared by atomic deposition. New indolo[3,2,1-jk]carbazole derivatives as sensitizers with phenothiazine unit an acetylene linkage containing either aldehyde or cyanoacrylic acid designed, synthesized characterized. However, lack anchoring ability –CHO group demonstrated. It found that has important...
Two new compounds with an N-octyl phenothiazine core substituted at C(7) position via a triple bond imidazole-containing butyl or dodecyl chains bearing on the opposite side cyanoacrylate moiety were synthesized. Photophysical and electrochemical studies performed to evaluate possibility of applying them in dye-sensitized solar cells (DSSCs). The investigations supported by density functional theory time-dependent DFT. synthesized dyes showed similar absorption profile ranging from 250 600...
Abstract New quinolines bearing a 2,2′‐bithiophene motif have been prepared through Ru‐ and In‐catalyzed reactions as well by Suzuki cross‐coupling reactions.
