Abstract: 본발명은이오노모형발광고분자를이용한고분자전기발광소자에대한것이다. 본발명의고분자는종래에사용되어왔던공액, 비공액고분자와는달리그 구조가특수하고열 안정성이아주우수하여발광수명을개선할수 있는고분자로서부분적으로약 15 mol% 이하의이온기를함유하고있으며이온적가교로인하여이온들이많이모여있는영역과비이온성고분자사슬들이모여있는영역으로구분된미세상분리구조를형성한다. 이고분자가함유하고있는이온기는전자를잡아당기는역할과동시에발광에도참여할 수있다. 주사슬이공액으로이루어진공액형발광이오노머와주사슬이비공액으로이루어진비공액형발광이오노머가존재하며이들의조합인공액-비공액발광이오노머도가능하다. 주사슬과곁사슬의공액여부와종류, 그리고이온기와이에치환되는짝이온의종류에따라그 전기적특성과발광특성이다르게나타난다. 본발명의이오노머형발광고분자는 2V의낮은전압에서도파란색빛을발산하며, 발광전기소자가열에매우안정하여소자의수명을연장시킬수 있다.
