Charge-transfer complexes (CTC) exhibit promising application in scientific field. A prototype CTC (TTF-TCNQ), formed by charge donating (tetrathiafulvalene) and charge accepting (tetracyanoquinodimethane) molecule, was systematically studied by Raman method. By combining Raman and synchrony X-ray diffraction (XRD), we investigated the high-pressure structures of TTF-TCNQ up to 15 GPa, and did not observe any first-order phase transition. Finally, a detailed evolution of structure for TTF-TCNQ, versus pressure, is provided, offering a new pathway to investigate the structural stability of CTC.
电荷转移复合物（CTC）在科学领域展现出了广阔的应用前景。一种由供电荷分子（四硫富瓦烯）和受电荷分子（四氰基对苯二醌二甲烷）形成的典型电荷转移复合物（TTF-TCNQ），通过拉曼光谱法进行了系统研究。通过结合拉曼光谱和同步X射线衍射（XRD），我们研究了TTF-TCNQ在高达15吉帕斯卡压力下的高压结构，未观察到任何一级相变。最后，给出了TTF-TCNQ结构随压力的详细演变情况，为研究电荷转移复合物的结构稳定性提供了一条新途径。
