revealing a helically arranged octamer, (R,R,R,R,R,R,R)-3, which showed intense circularly polarized luminescence (CPL) both in solution and in the solid state. The fluorescence quantum yields (ΦFL) in solution and in the solid state were 0.90 and 0.22, respectively, and the glum values in solution and in the solid state were +2.2×10−3 and +7.0×10−3, respectively. This is one of the highest solid-state CPL
合成了一系列低聚
萘并二恶英,揭示了一个螺旋排列的八聚体(R,R,R,R,R,R,R,R)-3,在溶液和固态下均显示出强烈的圆偏振发光(
CPL)。荧光量子产率(Φ FL)在溶液中和在固态下为0.90和0.22,分别与克LUM在溶液中和在固体状态值+ 2.2×10人-3 + 7.0×10和-3,分别。这是最高的固态
CPL之一克LUM尚未报告的值。高Φ FL和克LUM值是由于刚性,以及这样的事实:(- [R ,- [R ,- [R ,- [R ,- [R ,- [R ,- [R )- 3是一个非平面分子。此外,(R,R,R,R,R,R,R,R)-3在
化学和立体
化学上都是高度稳定的。
