Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Thi Minh Ha Vuong, once mentioned the application of 1439-36-7, Name is 1-(Triphenylphosphoranylidene)propan-2-one, molecular formula is C21H19OP, molecular weight is 318.35, MDL number is MFCD00008774, category is phthalazine. Now introduce a scientific discovery about this category, Safety of 1-(Triphenylphosphoranylidene)propan-2-one.
Blue highly fluorescent boron difluoride complexes based on phthalazine-pyridine
Three new boron difluoride complexes based on phthalazine-pyridine, denoted (6), (7) and (8), have been synthesized and their photophysical and electrochemical properties have been studied. Solutions of these new BF2-complexes exhibit an intense blue fluorescence under UV light at low concentrations. Fluorescence quantum yields (QYs) have been determined by photoluminescence (PL) spectroscopy and decay times (tau) by semi-empirical methods. QYs of (6), (7) and (8) vary from 25% to 79%. HOMO and LUMO energy levels have been estimated by cyclic voltammetry and PL spectroscopy. The HOMO and LUMO energy levels, at similar to -5.3 eV and similar to -2.3 eV, respectively, make these new complexes interesting candidates as blue emitters in OLED applications.
