Four- and five-membered 1,2-telluraplatinacycles incorporated into dibenzobarrelene and triptycene skeletons were synthesized by the reaction of bis(dibenzobarrelenyl) ditelluride and bis(triptycyl) ditelluride, respectively, with [Pt(η2-norbornene)(PPh3)2] in the presence of PPh3. These complexes emit strong, orange phosphorescence in the solid state at room temperature (λem = 622–676 nm). Ligand-exchange
通过分别与 [Pt(η2-norbornene)(PPh3)2] 的双 (dibenzobarrelenyl) 二碲化物和双 (triptycyl) 二碲化物反应合成四元和五元 1,2-碲铂环并入二苯并碲烯和三苯乙烯骨架在 PPh3 存在下。这些复合物在室温下以固态发出强烈的橙色磷光 (λem = 622–676 nm)。五元碲铂环与双齿膦配体的配体交换反应产生了一系列衍生物,这些衍生物发出一系列颜色(蓝色到橙色,λem = 507–596 nm),并具有高发射量子产率(最大 ΦF = 0.93)。室温下的固态,观察到蒸气发光。
