摘要：

Three binary charge-transfer cocrystals (I, II, and III) and ten cocrystal solvates (IV(1)IV(10)) were prepared in different solvents, involving 1-phenyl-3-(pyren-1-yl) prop-2-en-1-one (PPPO) as electron donor (D) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) as electron acceptor (A). X-ray diffraction data, vibrational spectroscopy, thermal behaviors, and diffuse reflectance absorption spectroscopy were exploited to investigate their structures. The different charge-transfer interaction mode and molar ratio between donor and acceptor in these crystals can be affected by the change of solvents. In addition, PPPO and TCNQ can selectively accommodate aromatic solvents relative to other solvents except methanol to form an isostructural microporous framework with solvent residing in the channels. These results demonstrate that these crystals can have potential applications in purification and separation of aromatic hydrocarbons.
