Related Products of 13991-08-7, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.13991-08-7, Name is 1,2-Bis(diphenylphosphino)benzene, molecular formula is C30H24P2. In a patent, introducing its new discovery.
We demonstrate highly efficient organic ultraviolet photodetectors using 4,4?,4??-tris[3-methyl-pheny(phenyl)amino]triphenylamine (m-MTDATA) and two excellent phosphorescent Cu(I) complexes, [Cu(DPEphos)(DPPz)]BF4 (CuDD) (DPEphos = Bis[2-(diphenylphosphino) phenyl]ether, DPPz = dipyrido(3,2-a:2?,3?-c) phenazine) and [Cu(DPEbenz)(DPPz)]BF4 (CuBD) (DPEbenz = 1,2-bis(diphenylphosphino) benzene) to act as the electron donors and acceptors, respectively. The optimized photodetector based on CuDD delivers a photocurrent of 588 muA/cm2 at -12 V, corresponding to a response of 560 mA/W under an illumination of 365 nm UV light irradiation with an intensity of 1.05 mW/cm 2 and a detectivity of 2.82 × 1011 cm Hz 1/2/W. The high response is attributed to the larger band offset at m-MTDATA/CuDD heterojunction, the suppression of radiative decay of m-MTDATA and efficient electron transfer from m-MTDATA to CuDD. The working mechanism of harvesting high performance is also discussed in detail.
