Chalcone based materials are widely used in many industrial applications. The two new similar chalcone based single crystals, namely (E)-3-(4-(benzyloxy)phenyl)-1-(4-hydroxyphenyl)prop-2-en-1-one (Crystal A) and (E)-1-(4-(benzyloxy)phenyl)-3-(4-hydroxyphenyl)prop-2-en-1-one (Crystal B) were synthesized and grown as single crystals by slow evaporation solution growth technique in acetone. The structures of the grown crystals were solved and refined by single crystal XRD and this demonstrates that crystal A shows an orthorhombic system with a space group of Pca21 and crystal B crystallizes in a monoclinic system with a space group of C2/c. The morphology of the crystals A and B was predicted using WINXMORPH. The hyperpolarizability studies were carried out for the chalcone single crystals using density functional theory (DFT) - triply parameter hybrid model DFT/B3LYP using GAUSSIAN 03. The calculated first order hyperpolarizability was found as 0.1314 × 10−30 e.s.u. for crystal A and 0.188 × 10−30 e.s.u. for crystal B. The second harmonic generation was studied by Kurtz–Perry test. The comparison statement of the enone shifted material properties enumerates interesting results in all the studies.
基于
查尔酮的材料被广泛应用于许多工业领域。通过在
丙酮中缓慢蒸发溶液生长技术,合成并生长了两种类似的
查尔酮基单晶,即(E)-3-(4-(苄氧基)苯基)-
1-(4-羟基苯基)丙-2-烯-1-酮(晶体 A)和(E)-1-(4-(苄氧基)苯基)-3-(
4-羟基苯基)丙-2-烯-1-酮(晶体 B)。通过单晶 XRD 对生长出的晶体的结构进行了解析和完善,结果表明晶体 A 呈空间群为 Pca21 的正方晶系,晶体 B 则呈空间群为 C2/c 的单斜晶系。晶体 A 和 B 的形态是通过 WINXMORPH 预测的。利用密度泛函理论(DFT)--三参数混合模型 DFT/B3LYP(使用 GAUSSIAN 03)对
查尔酮单晶进行了超极化率研究。计算得出晶体 A 的一阶超极化率为 0.1314 × 10-30 e.s.u.,晶体 B 为 0.188 × 10-30 e.s.u.。烯酮偏移材料特性的比较说明列举了所有研究中有趣的结果。
