Tetraindeno-fused spirofluorene based blue emitters with thioxanthene (Spiro-4S) or dioxothioxanthene (Spiro-4SO2) substitutes have been synthesized and characterized. Their thermal, photophysical, and electrochemical properties have also been studied. The appealing feature of this study is their 3D geometries with cruciform conjugated backbones, whose interactions are clearly revealed by single crystal analysis. Notably, this conformation is beneficial for reducing the trend of aggregation quenching and it is highly expected that these two molecules will have isotropic charge-transport and optical properties.

带有噻吨或二氧代噻吨并取代的刚性3D四茚并稠螺螺的合成，结构和光电性能

合成并表征了具有噻吨蒽（Spiro-4S）或二氧代噻吨蒽（Spiro-4SO2）替代物的四联萘基螺芴基蓝色发光体。还已经研究了它们的热，光物理和电化学性质。这项研究的吸引人之处在于其具有十字形共轭骨架的3D几何形状，其相互作用通过单晶分析清楚地揭示出来。值得注意的是，该构象有利于减少聚集猝灭的趋势，并且高度期望这两个分子将具有各向同性的电荷传输和光学性质。
