An Electrochemical Study on Photoluminescent and Electroluminescent Characteristics of $Zn(BOX)_{2}$ and $Zn(BTZ)_{2}$

($Zn(BOX)_{2}$와 $Zn(BTZ)_{2}$의 광발광 특성 및 전계발광 특성에 대한 전기 화학적 연구

Organic Electroluminescent devices(OELD) consisted of multilayer structures have been studied for the application the application to flat-panel display. Metal-chelate complexes, zinc bis(2-(2-hydroxyphenyl)benzoxazolate) ($Zn(BOX)_{2}$) and zinc bis(2-(2-hydroxyphenyl)benzothiazolate) ($Zn(BOX)_{2}$), have been intensively investigated as an white-light emitting layer and recognized to have good electroluminescent(EL) properties. In this study, ($Zn(BOX)_{2}$) and ($Zn(BTZ)_{2}$) were synthesized and characterized by FT-IR, $^{1}H-NMR$, UV-VIS and PL. Their EL properties were also studied and their ionization potential(IP) and electron affinity(EA) were also measured by cyclic voltammetry(CV).
