自宋代以来,经筵一直是一种士人教化帝王的仪式传播。由于满汉族群差异,清初君臣之间缺失共通意义空间,以致于经筵的仪式功能难以发挥。在康熙年间,经历文化涵化和文化移转之后,经筵场域的共通意义空间完成重构。同时,皇权强制力的介入将经筵改造成训诫士人的工具。此后,经筵成为一种被压抑的仪式传播,并伴随着文化空间的萎缩和历史记忆的扭曲。

以2,3-二苯基吡嗪(H_2dpp)、5-甲基-2,3-二苯基吡嗪(H2mdpp)和2,3-二苯基喹喔啉(H_2dpq)为配体,乙酰丙酮(Hacac)为辅助配体,合成了一类单核和双核金属铂配合物[Pt(Hdpp)(acac)](1)、[Pt2(dpp)(acac)2](2)、[Pt(Hmdpp)(acac)](3)和[Pt(Hdpq)(acac)](4),并且得到了配合物2、3和4的晶体结构数据。通过对单核配合物1的类似物配合物3和双核配合物2的配位平面、分子扭曲程度等的晶体结构分析,我们合理地推断以2,3-二苯基吡嗪为配体的双核配合物2具有比相应的单核配合物1更加扭曲的分子平面。通过对配合物1和2的紫外-可见吸收光谱和激发光谱的比较,发现由于双核配合物2在激发态的构型变化造成了激发光谱中最低能带比相应的最低能量吸收带光谱红移了18 nm。因此,尽管双核配合物2具有与单核配合物1类似的紫外-可见吸收光谱,最低能吸收带仅比单核配合物1红移5 nm,但是双核配合物2的最大发射峰值λmax为609 nm,比单核配合物1(λmax=546 nm)红移了63 nm。双核配合物2的发射光谱红移现象与配合物的分子构型直接相关。分子扭曲程度更大的双核配合物2在激发态可能发生了一个向平面性更好的构型转变过程,从而进一步降低了激发态能量,造成了发射光谱的红移。
