The novel 2D bismuth–camphorate IEF‐1, formulated as [Bi(L)(HL)] (where H₂L = camphoric acid), has been successfully isolated as large single crystals and easily scaled up by hydrothermal synthesis. The crystalline structure of IEF‐1 was unveiled by single‐crystal X‐ray diffraction, in the monoclinic space group P2₁, and fully characterized by using several standard solid‐state techniques. IEF‐1 material is thermally stable up to ca. 240 °C without any visible structural change. In addition, the study of the nonlinear optical (NLO) properties of IEF‐1 by second harmonic generation (SHG) microscopy evidenced that IEF‐1 is noncentrosymmetric and has a more intensive blue component that may be explained by the ligand to metal charge transfer behavior.

非线性光学活性铋-樟脑酸酯配位聚合物

新颖的二维铋樟脑型IEF-1配制成[Bi（L）（HL）]（其中H ₂ L =樟脑酸），已成功分离为大单晶，可通过水热合成轻松放大。IEF-1的结晶结构是通过单晶X-射线衍射亮相，单斜晶系空间群P 2 ₁，并且通过使用多种标准固态技术完全表征。IEF-1材料的热稳定性最高可达。240°C，无明显结构变化。另外，通过二次谐波（SHG）显微镜对IEF-1的非线性光学（NLO）性质的研究证明，IEF-1是非中心对称的，并且具有更强的蓝色成分，这可以通过配体向金属的电荷转移来解释。行为。
