Structural, absorption, and molecular properties of o,o'-dihydroxyazo resorcinol dyes bearing an acryloyloxy group
(Elsevier B.V., 2017)
To the best of our knowledge, this is the first study reporting the synthesis and characterization of o,o?-dihydroxyazo dyes bearing an acryloyl group. The o,o?-dihydroxyazo dyes were synthesized through coupling of ...
Fabrication and characterization of magnesium and calcium trimesate complexes via ion-exchange and one-pot self-assembly reaction
(Elsevier B.V., 2018)
Using two different synthesis methods, two diversified magnesium and calcium complexes were successfully prepared. When the ion exchange method was used, C9H14MgO11.H2O and C18H30Ca3O24 complexes were obtained. When the ...
