Characteristics of Organic EL Device using PDPMA and Heat-Treated 8-Hydroxyquinoline-Zinc Complex

Optical, Magnetic, Electrochemical, and Electrical Properties of 8-Hydroxyquinoline-Based Complexes with Al3+, Cr3+, Mn2+, Co2+, Ni2+, Cu2+, and Zn2+

“…Tris(8-hydroxyquinoline) aluminum(III), AlQ 3 , and bis(8-hydroxyquinoline) zinc(II), ZnQ 2 , were used as-received from Sigma. The other bis or tris(8-hydroxyquinoline) M materials with M = Cr, Mn, Co, Ni, and Cu were synthesized in our laboratory, following standard procedures. − Typically, 1 g (6.88 mmol) of 8-hydroxyquinoline, HQ, (Sigma) was dissolved in 150 mL of ethanol; the solution was stirred and heated. A separate solution was prepared with the chosen cation M(II) or M(III) chloride salt in water so that the amount of HQ to metal in the solution is in a 2:1 or 3:1 ratio, respectively.…”

Investigations of Different Phases Responsible for Changes in Optical Properties of Organic Semiconducting Device Material Thin Films

“…The water molecules are loosely attached to zinc atom and are easily removed by heating the compound to 135 ∘ C [15]. Anhydrous Znq 2 is amorphous in nature and tends to form tetramer at temperatures slightly higher than 135 ∘ C [12].…”

Study on environmental stability of a Zn based metal chelate organic small molecule in powder and thin films

“…2 An exothermic peak for Znq 2 .2H 2 O at 199 o C may be due to release of energy by fusion of anhydrous Znq 2 molecules into oligomers. Next strong endothermic peak occurs at 357 o C followed by decomposition at 440 o C. The sublimation temperature of Znq 2 is 357 o C. The water molecules are loosely attached to zinc atom and are easily removed by heating the compound to 135 o C [14]. Anhydrous Znq 2 molecule is amorphous in nature and tends to form tetramer at temperatures slightly higher than 135 o C 12 .…”
