中文摘要：
通过金刚石对顶砧（DAC）高压装置产生高压,利用原位高压同步辐射能量色散X射线衍射（EDXD）和同步辐射远红外光谱研究了压力对DPP-11[2,5-二-（11-十一醇基）-3,6-二-（2-噻吩基）-1,4-二酮吡咯并[3,4-c]吡咯]固体及其在水溶液中胶束体系的影响.实验结果表明,在准静水压条件下,DPP-11固体没有发生相变,但随着压力的增加,分子间的π-π相互作用明显增强.在DPP-11胶束中发现了DPP-11固体中新的远红外吸收峰,此峰随着压力的增加而蓝移,这是由于胶束中π共轭染料基团的π-π相互作用增强所致.
英文摘要：
In-situ synchrotron X-ray diffraction and far-IR spectra of DPP-11{2,5-bis[ 11-（1-pyridinium） alkyl]-3,6-bis（2-thienyl）-1,4-dioxopyrrolo[ 3,4-c ] pyrrole ditosylate salts t and its micelles in aqueous solution were studied. Although X-ray studies show no indication of phase transition, however, the π-π interactions become stronger with increasing pressure which can be deduced from far-IR spectra. A new far-IR absorption peak is found to be related to the π-conjugated aromatic dyes in DPP-11 micelles. Upon increasing pressure, the peak shifted toward higher wavenumber region due to the stronger π-π interactions.
