Anthracene assembled hydrocarbon: The title aromatic hydrocarbon having four anthracene units was synthesized by the McMurry coupling of di(1-anthryl) ketone in 65 % yield. The X-ray and DFT calculations revealed that the molecule took a C2 symmetric structure with the ap conformation about the C(sp3)−C(sp3) single bond and a pair of stacked anthracene units. In the fluorescence spectrum, this compound
蒽组装烃:通过二(1-蒽基)酮的McMurry偶联以65%的产率合成具有四个蒽单元的标题芳烃。X 射线和 DFT 计算表明该分子采用C 2对称结构,p构象围绕 C(sp 3 )-C(sp 3 ) 单键和一对堆叠的蒽单元。在荧光光谱中,该化合物在 450 nm 处显示出长寿命的宽发射带,可归属于准分子型发射。借助非共价相互作用图和构象分析,根据分子结构讨论了这种光物理性质。
