有机电致发光材料、装置和相关方法
摘要：
本发明涉及有机电致发光材料、装置和相关方法。一种由第一化合物和第二化合物的混合物形成的组合物，其中所述第一化合物具有与所述第二化合物不同的化学结构。所述第一化合物和所述第二化合物均是有机化合物。所述第一化合物和所述第二化合物中的至少一者含有至少一种较低丰度的稳定同位素原子。所述第一化合物具有蒸发温度T1，且所述第二化合物具有蒸发温度T2，其中T1和T2均在100到400℃之间，且T1‑T2的绝对值小于20℃。所述第一化合物在所述混合物中具有浓度C1并且在膜中具有浓度C2，所述膜是通过在高真空沉积工具中以1×10‑6托到1×10‑9托之间的腔室基础压力、以2沉积速率在与被蒸发的所述混合物相距预定距离定位的表面上蒸发所述混合物而形成的；且其中(C1‑C2)/C1的绝对值小于5％。
摘要（英）：

A composition formed of a mixture of a first compound and a second compound wherein the first compound has a different chemical structure than the second compound. The first compound and the second compound are both organic compounds. At least one of the first compound and the second compound contains at least one less abundant stable isotope atom. The first compound has an evaporation temperature T1 and the second compound has an evaporation temperature T2 where both T1 and T2 are between 100 to 400 ° C. and the absolute value of T1-T2 is less than 20 ° C. The first compound has a concentration C1 in said mixture and a concentration C2 in a film formed by evaporating said mixture in a high vacuum deposition tool with a chamber base pressure between 1×10−6 Torr to 1×10−9 Torr, at a 2Å/sec deposition rate on a surface positioned at a predefined distance away from the mixture being evaporated; and wherein absolute value of (C1-C2)/C1 is less than 5%.
