In this work, an ortho hydroxyl azobenzene heterocyclic dye has been prepared by using the post-modification synthetic strategy via the Fenton-type reaction, namely in situ Cu(II)/H2O2 catalytic oxidation and complexation, and the following demetallization. Special attention is given to the structural and spectral differences between dyes before and after implanting the ortho phenolic hydroxyl group...
Tris(8-hydroxyquinoline)aluminum(III) (Alq3) is characterized by crystallization in polymorphism both under vapor deposition and solvent evaporation. In this article, crystal growth of Alq3 in several organic solvents is studied. High quality bulk single crystals or crystalline microstructures are obtained, which depends on the varied conditions of crystallization. Two new crystalline solvates of...
