Synthetic Route of 52409-22-0, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 52409-22-0, molcular formula is C51H42O3Pd2, introducing its new discovery.
Synthesis and photovoltaic properties of an alternating polymer based on benzo[1,2-b:4,5-b?]dithiophene and fluorine substituted 4,7-dithiophene-2-yl-2,1,3-benzothiadiazole
An alternating polymer (PBDTFC10DBT) with benzo[1,2-b:4,5- b?]dithiophene (BDT) as electron-rich unit and 4,7-bis(4-decylthiophen-2- yl)-5-fluorine-2,1,3-benzothiadiazole (FC10DBT) as electron-withdrawing unit was synthesized and characterized. PBDTFC 10DBT showed similar absorption property with that of the counterpart polymer without fluorine atom (PBDTC10DBT). However, the low-lying highest occupied molecular orbit (HOMO) energy level of PBDTFC10DBT was -5.42 eV, about 0.22 eV deeper than that of PBDTC10DBT. In order to study the photovoltaic properties of the materials, polymer solar cells (PSCs) were fabricated with PBDTFC10DBT as donor blended with [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) as acceptor. The power conversion efficiency (PCE) of PSC was 1.19% with a high open circuit voltage (Voc) of 0.62 V for an optimized PBDTFC 10DBT:PC61BM ratio of 1:4, in comparison with that of PBDTC10DBT-based device (PCE of 0.99% with Voc of 0.53 V). This study indicated that fluorine substituted 4,7-dithiophene-2-yl-2,1,3- benzothia-diazole based copolymers would be promising material for the application in polymer solar cells.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 52409-22-0 is helpful to your research. Synthetic Route of 52409-22-0
