No institution will require any rights from this work too. The difference in the three dyes is majorly related to the acceptor part, which has variation in electron withdrawing nature, where the anchoring of TiO2 occurs. Based on the strategy, several arylamine donors have been employed to develop highly efficient organic dyes. Then, 1,2 —diaminobenzene react with S2 in the presence of water and glycerol, which gave the corresponding compound S3 via cyclocondensation reaction. The structures of the resulting compounds were also established from elemental analyses and spectral data, which are included in the experimental part.
A call for studies. The emission spectra of the dyes were recorded in dichloromethane solutions Figure 5 are in similar in nature and the effect peripheral units is not significant. No institution will require any rights from this work too. Each of these compounds exhibited two major absorption bands were observed in the range of nmnm with high molar extinction coefficient. Antitumor potential and possible targets of phenothiazine-related compounds. The compound with long alkyl chain substituent on the nitrogen atom of phenothiazine displayed a red shift with an increased absorptivity.
DOI: Synthesis and biological activity of N-acylphenothiazines. The synthetic pathways for the dyes involved stepwise protocol. The film absorption band displayed a broader band with respect to those in solutions.
Then using nichrome wire loop, 3 mm external diameter, a loopful of suspension was inoculated on the surface of each of LowensteinJensen medium containing the test compounds. None of the compounds produced inhibition zone against Gram-negative organisms like E. Based on the strategy, several arylamine donors have been employed to develop highly efficient organic dyes.
Keywords: benzimidazole, phenothiazine, acceptor unit, DSCs, sensitizer Introduction Organic materials are suitable for application in light emitting diodes, thin film transistors and photovoltaic devices have received immense attention in recent years.
Optical properties To quantify the light absorbing capacity of the dyes, optical spectra of the dyes and their precursors were measured in dichloromethane solution. Synthesis and antimicrobial activity of new triazolopyridinyl phenothiazines. Pharmacognostical, antibacterial and antifungal potentials of the leaf extracts of Pithecellobium dulce Benth. This contribution brings further credit to these molecular designs as efficient sensitizers for DSCs, enroute for a cheap and less toxic substitute to ruthenium based sensitizers and silicon based photovoltaics as potential eco-friendly energy candidates in future. The emission spectra of the dyes were recorded in dichloromethane solutions Figure 5 are in similar in nature and the effect peripheral units is not significant.
The bottle was shaken with the help of a mechanical shaker for 2 min.
