Electric Literature 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.
A series of cationic Pt(II) complexes with chelating bis-carbene and P,P- or P,S-ligands, viz. [(C^C)Pt(X^Y)][BF4]2 (2a?e), where C^C = methylenebis(3-methyl-1H-imidazol-1-yl-2-ylidene, and X^Y = Ph2PCH2CH2PPh2 (dppe) (a), Ph2P(CH2)3PPh2 (dppp) (b), 1,2-(Ph2P)2C6H4 (dppbz) (c), [Fe(eta5-C5H4PPh2)2] (dppf) (d), and Ph2PCH2CH2SPh (e), were synthesized and structurally characterized by NMR and MS spectroscopy and by single-crystal X-ray diffraction analysis. Furthermore, photophysical measurements showed that these compounds were non-emissive at room temperature. However, when cooled to 77 K, compounds 2a, 2b and 2c showed weak luminescence in the near UV region with emission maxima in the 380?395 nm range.
