The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Tong, Bihai, once mentioned the application of 623-25-6, Name is α,α’-Dichloro-p-xylene, molecular formula is C8H8Cl2, molecular weight is 175.06, MDL number is MFCD00000920, category is phthalazine. Now introduce a scientific discovery about this category, Category: phthalazines.
Two cyclometalated dimeric from complexes, [{Ir(mu-Cl)(mu-ppa)(dmppa)}(2)] (dimer 1) and (dmppa)Ir(mu-Cl) (mu-ppa)Ir(ppa) (dimer 2) (dmppa = 1-(2.6-dimethylphenoxy)-4-phenylphthalazine, ppa =1-hydroxy1-4-phenylphthalazine), containing the bridging phthalazine ligands and bridging chlorides have been synthesized and fully characterized. Dimer 1 can form a noncovalently linked crystalline porous frameworks. The emission wavelength of dimer 1 in CH2Cl2 solution was 596 nm and the further hydrolysis of phenolic groups red shift the emission of dimer 2 to 634 nm. Two dimers have relatively high quantum efficiency, i.e., ca. 0.21 for dimer 1 and 0.3 for dimer 2 in CH2Cl2 solution. (C) 2011 Elsevier B.V. All rights reserved.
