The present invention is directed to heterocyclic compounds which are antagonists of CGRP receptors and may be useful in the treatment or prevention of diseases in which CGRP is involved, such as migraine. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which CGRP is involved.
High colour rendering index and colour stable hybrid white efficient OLEDs with a double emitting layer structure using a single phosphorescence dopant of heteroleptic platinum complexes
characterizations of the corresponding europiumcomplexes reveal that the sensitization efficiencies (ηsens) are close to 100% and the total photoluminescence quantum yields can reach up to 84%. Most importantly, these structurally rigid luminescent europiumcomplexes exhibit outstanding photostability and thermostability. Unlike the widely used β‐diketone complexes that are easily photodegraded, ND‐based
在发光镧系元素络合物(LLC)领域以及有关有机发光过程的许多学科中,抗光漂白是一个关键的挑战。在这项工作中,开发了一种结构上刚性的有机配体,即4-羟基-1,5-萘啶(ND),它不仅可以有效地敏化emission的发射,而且还表现出独特的光稳定性。合成了一系列具有不同取代基的ND衍生物,并系统地研究了它们的单重态和三重态激发态能级。相应的铕络合物的光物理表征揭示,敏化效率(η SENS)接近100%,总的光致发光量子产率可达到84%。最重要的是,这些结构刚性的发光euro络合物表现出出色的光稳定性和热稳定性。与广泛使用的容易被光降解的β-二酮配合物不同,基于ND的螯合物在200小时内的UV老化测试(10 W m -2 340 nm紫外线A照射)下没有显示出明显的降解。如此出色的抗紫外线性甚至优于著名的化合物三(8-羟基喹啉)铝(Alq 3)。讨论了可能的原因,并提出了设计光稳定LLC的一般规
