A “basophilic method” for phenolic hydroxyl bridged lanthanide coordination polymers (CPs) was developed. With this method, eleven CPs with the general formula of [Ln(HL1)L1·H2O]n (Ln = Tb (1), Nd (2), Eu (3), Gd (4), La (5), Er (6), Y (7), H2L1 = 4-methyl salicylic acid) and [Ln(HL2)L2·2MeOH]n (Ln = Eu (8), Tb (9), Gd (10), La (11), H2L2 = 3-hydroxy-2-naphthoic acid) were synthesized based on two ligands, and five of them (1–4 and 8) were characterised by X-ray single crystal diffraction. The powder X-ray diffraction patterns (PXRD) of complexes showed that 1–7 are isostructural, 8–11 are isostructural. Furthermore, 1 was characterised by Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), differential thermal analysis (DTA), elemental analysis (EA), one and two photon luminescence were investigated in detail.
开发了一种用于酚羟基桥接镧系元素配位聚合物(CP)的“嗜碱性方法”。通过该方法,11个CP的通式为[Ln(HL1)L1·H2O]n(Ln = Tb(1),Nd(2),Eu(3),Gd(4),La(5),Er) (6)、Y (7)、H2L1 = 4-甲基水杨酸) 和 [Ln(HL2)L2·2MeOH]n (Ln = Eu (8)、Tb (9)、Gd (10)、La (11) ,H2L2 = 3-羟基-2-萘甲酸)基于两个配体合成,其中五个(1-4和8)通过X射线单晶衍射进行了表征。配合物的粉末X射线衍射图(PXRD)表明1-7是同构的,8-11是同构的。此外,还通过傅里叶变换红外(FT-IR)、热重分析(TGA)、差热分析(DTA)、元素分析(EA)对1进行了表征,并对一光子和二光子发光进行了详细研究。
