研究了高压下Pt（dpg）_2薄膜的光学性质。随着压力的增加，复合物在可见光区的两个吸收带急剧向更长的波长移动。金属-配体电荷转移（M-L）带的红移速率约为1900 cm-1 GPa-1，5d-6p带的红移速率约为3000 cm-1 GPa-1。这些值是已知的一维d8金属配合物中最大的。在金刚石压砧压力室中观察了不同压力下薄膜的颜色。Pt（dpg）2的颜色由大气压下的红棕色变为0.27 GPa下的棕色、0.69 GPa下的绿色、1.24 GPa下的黄绿色和1.92 GPa下的黄色。这种材料可以用作GPa范围0-2的压力指示器。
The optical properties of thin films of Pt(dpg)2 have been studied at high pressures. Two absorption bands of the complex in the visible region shifted sharply to longer wavelengths with increasing pressure. The rates of the red shift with pressure were ca.–1900 cm–1 GPa–1 for the metal-to-ligand charge-transfer(M–L) band and –3000 cm–1 GPa–1 for the 5d-6p band. These values are the largest in the known one-dimensional d8 metal complexes. The colours of the thin films in the diamond-anvil pressure cell were observed visullay at various pressures. The colours of Pt(dpg)2 turned from red–brown at atmospheric pressure to brown at 0.27 GPa, green at 0.69 GPa, to yellow–green at 1.24 GPa and yellow at 1.92 GPa. This material can be utilized as an indicator of pressure over a GPa range 0–2.
