Photo-Physical Measurements of Fuctional Organic Materials under High Pressure

本研究的目的是开发高压光物理测量系统，并分析具有显著光电功能的有机材料的功能与结构之间的相关性。主要结果如下。1)构建了能够进行500mpa光吸收光谱、光电导率、拉曼散射测量的高压测量系统。其性能得到了充分的验证。2)对典型的光导聚合物PVK-TNF配合物进行了高压下的光吸收光谱测量，观察到光吸收光谱的几个区域变化，表明压力的施加使分子链中的排列更加紧密，促进了CT配合物的形成。3)通过高压x射线和罗马测量揭示了高压的作用，诱导了斜扭式向反式的构象转变，形成了结晶度更完美的晶体。4)获得了尿素-石蜡加合物在高压下固-固相转变的一些新数据。5)利用光电二极管阵列多光度计对部分蛋白质的凝胶化过程进行了监测。

The objectives of this study were to develop the measuring system for photo-physical measurement under high pressure and to analyze the correlation between the functionalities and structures in organic materials with notable photo-and electric functions. And major results are followings.1) The high pressure measuring system which is capable of conducting the photo-absorbance spectra, photo-conductivity, Raman scattering measurements up to 500 MPa was constructed. And its performance was fully ascertained.2) The photo-absorbance measurements under high pressure were conducted for typical photo-conductive polymers, PVK-TNF comples, and several district changes in photo-absorbance spectra were observed, suggesting that the application of pressure induces the closer packing in the molecular chains and promotes the CT complex formation.3) The application of high pressure was revealed by high-pressure X-ray and Roman measurements to induce the conformational transition from gauche to trans and the crystal formation with more perfect crystalinity.4) Several new data on the solid-solid phase transition under high pressure were obtained for urea-paraffin adducts.5) The multi-photospectrometer with photo-diode array was utilized to monitor the gelletion process in some protains.
