金属合金、金属间化合物等无机混合晶体或固溶体是由两种或多种原子或离子均匀混合在晶体中组成的。[1-3]它们自古以来就被广泛制备和用作日常生活的结构材料。在寻找具有光学、电学和磁学特性的新型功能材料的过程中，混合晶体的形成已被广泛研究。由于无机材料的球形结构，原子和离子很容易在无机材料中混合，因此通常通过改变组分的组合和混合比例来进行功能的集成和微调[4]。另一方面，从溶液中重结晶或从熔体中结晶通常用于结晶有机化合物的纯化。对有机混合晶体的研究主要集中在晶态下明确的分子复合物，例如包合物晶体、[4]氢键共晶、[5]和电荷转移复合物。[6]由多种有机分子组成的有机固溶体或合金的形成较少受到关注。 Kitaigorodsky指出，分子结构的相似性在有机固溶体的形成中起着至关重要的作用，[1]以及一些例子，例如正链烷烃，[7]二羧酸，[8]萘衍生物，[9]
Inorganic mixed crystals or solid solutions such as metal alloys and intermetallic compounds are composed of two or more kinds of atoms or ions homogeneously mixed in the crystal.[1–3] They have been widely prepared and utilized as structural materials for daily life since ancient times. Formation of mixed crystals has been extensively investigated in the search for new functional materials with optical, electrical, and magnetic properties. Integration and fine-tuning of the functions have been often carried out by varying combinations of the components and the mixing ratios,[4] since the atoms and ions are easily mixed in the inorganic materials due to their spherical structures.On the other hand, recrystallization from solution or crystallization from the melt is generally used for purification of crystalline organic compounds. Studies on organic mixed crystals have focused chiefly on well-defined molecular complexes in the crystalline state, such as inclusion crystals,[4] hydrogen-bonded cocrystals,[5] and charge-transfer complexes.[6] Less attention has been paid to formation of organic solid solutions or alloys that are composed of many kinds of organic molecules. Kitaigorodsky pointed out that similarity of molecular structures plays a crucial role in formation of organic solid solutions,[1] and some examples such as nparaffins,[7] dicarboxylic acids,[8] naphthalene derivatives,[9]
