Öğe Chemical composition and antimicrobial activity of the essential oil of Anthemis wiedemanniana from Turkey(Springer, 2007) Kivcak, B.; Mert, T.; Saglam, H.; Ozturk, T.; Kurkcuoglu, M.; Baser, K. H. C.The chemical composition and antimicrobial activity of the essential oil from aerial parts of Anthemis wiedemanniana, an endemic taxon of Turkey, were investigated. Linalool (12.75%), 1,8-cineole (8.49%), hexadecanoic acid (6.09%), and chrysanthenone (5.67%) were found to be the main components among the 122 compounds characterized in the essential oil of Anthemis wiedemanniana. Antimicrobial activities were reported against 12 microorganisms and five yeast-like fungi by the disc diffusion method.Öğe CHEMICAL COMPOSITION AND ANTIMICROBIAL ACTIVITY OF THE ESSENTIAL OILS OF THREE Anthemis SPECIES FROM TURKEY(Springer, 2009) Kurtulmus, A.; Fafal, T.; Mert, T.; Saglam, H.; Kivcak, B.; Ozturk, T.; Demirci, B.; Baser, K.

Various studies have focused on the development of fused heterocyclic conjugated structures for hole transport materials. In this report, three novel ?-extended conjugated materials (M1-M3), based on thieno[3,2-b]thiophene (TT) and 4,4?-dimethoxytriphenylamine [TPA(OMe)2], were designed and successfully synthesized via Palladium (0) catalyzed Suzuki coupling reaction. Their optical, electrochemical, and thermal properties were investigated by UV-Vis, fluorescence, cyclic voltammetry, and thermal analysis. The materials were utilized as hole transport materials in p-i-n architecture perovskite solar cells, which displayed performances of open-circuit voltage (Voc) as high as 1,050 mV, a maximum short-circuit current (Jsc) of 16,9 mA/cm2, a maximum fill factor (FF) of 29.3%, and a power conversion efficiency (PCE) of 5.20%. This work demonstrated that thieno[3,2-b]thiophene and TPA(OMe)2-based structures are promising cores for high-performance hole transport materials in perovskite solar cell architecture.
