compounds based on hydroxynaphthene group have been prepared. Compound 2 was synthesized through the esterification of compound 1 in the acid conditions. They have been characterized by IR, EA and single crystal X-ray diffraction. Single X-ray diffraction reveals that compounds 1 and 2 belong to the P21/n and P21/c, respectively. It is obviously observed that there exist C/OH⋯O and the packing interactions
为了探索新的
发光材料,制备了两种基于羟基
萘基的化合物。化合物2通过化合物1在酸性条件下的酯化反应合成。它们已通过 IR、EA 和单晶 X 射线衍射进行了表征。单X射线衍射表明化合物1和2分别属于P 2 1 / n和P 2 1 / c。很明显,芳环之间存在C/O H⋯O和堆积相互作用。固态荧光光谱显示化合物1的最大值和2分别为 448 和 415 nm。发光发射最大值与化合物的堆叠相互作用一致。可以发现这两种化合物的熔点分别为 190–192 °C 和 78–80 °C。Hirshfeld 表面分析进一步表明紧密接触 C⋯C 是发光峰的原因,而 O⋯H/H⋯O 紧密键可以解释两种化合物的熔点。
