转子-定子相和polymer相中C60C8H8和C70C8H8的振动谱
Vibrational spectra of C60C8H8 and C70C8H8 in the rotor-stator and polymer phases
摘要:
C60-C8 H8和C70-C8 H8是转子-定子共晶的原型。我们提出了这些材料的红外光谱和拉曼光谱,并展示了转子-定子性质是如何反映在它们的振动特性。我们测量的振动光谱的聚合物相聚(C60 C8 H8)和聚(C70 C8 H8)产生的固态反应时发生加热。基于光谱,我们提出了一个连接模式的富勒烯在聚(C60 C8 H8),其中C60的对称性是D2 h。在用绿光或蓝光照射C60-C8 H8共晶时,观察到光化学反应,导致与热聚合类似的产物。
英文摘要:
C60-C8H8 and C70-C8H8 are prototypes of rotor-stator cocrystals. We present infrared and Raman spectra of these materials and show how the rotor-stator nature is reflected in their vibrational properties. We measured the vibrational spectra of the polymer phases poly(C60C8H8) and poly(C70C8H8) resulting from a solid state reaction occurring on heating. Based on the spectra we propose a connection pattern for the fullerene in poly(C60C8H8), where the symmetry of the C60 is D2h. On illuminating the C60-C8H8 cocrystal with green or blue light a photochemical reaction was observed leading to a similar product to that of the thermal polymerization.
