[EN] HETEROCYCLIC COMPOUND AND AN ORGANIC ELECTROLUMINESCENCE DEVICE COMPRISING THE HETEROCYCLIC COMPOUND [FR] COMPOSÉ HÉTÉROCYCLIQUE ET DISPOSITIF ÉLECTROLUMINESCENT ORGANIQUE COMPRENANT CE COMPOSÉ HÉTÉROCYCLIQUE
We synthesized diethynylbenzene macrocycles (DBMs), cyclic oligomers of diethynylbenzene, having functional groups in the periphery of the macrocyclic framework and investigated their self-association properties in solution resulting from π-π stacking interaction. The tetrakis-DBM having hexadecyl ester groups showed dimerization behavior not only in chloroform-d, but also in o-dichlorobenzene-d4.

본 발명은 유기발광소자에 사용가능한 보론 화합물 및 이를 포함하는 유기발광소자에 관한 것으로, 보다 자세하게는 [화학식 A] 내지 [화학식 D] 중에서 어느 하나로 표시되는 보론 화합물 및 이를 포함하는 유기발광소자에 관한 것으로서, 상기 [화학식 A] 내지 [화학식 D]는 발명의 상세한 설명에 기재된 바와 동일하다.
Butadiyne-bridged [44]- and [48]metacyclophanes having exo-annular t-butylgroups were prepared by intermolecular Eglinton coupling of the dimeric unit or by intramolecular ring closure of the linear tetramer. Comparison of the 1H and 13C NMR spectra of [44]metacyclophane with those of [48]cyclophane and diphenylbutadiyne revealed its prominent geometrical feature due to deformation of the triple bonds
通过二聚体的分子间Eglinton偶联或通过线性四聚体的分子内闭环制备具有环外叔丁基的丁二炔桥联的[4 4 ]-和[4 8 ]间环phanes 。比较[4 4 ]间环phane的1 H和13 C NMR谱与[4 8 ]环烷和二苯基丁二炔的1 H和13 C NMR谱,发现其突出的几何特征是由于三键由于线性变形而引起的。通过用硫化钠处理,以良好的产率将[4 4 ]甲基环环烷转变为[0 8 ]噻吩金属环烷。
