  摘要：

  新型发光三元有机-无机介孔杂化材料bpy-Ln-Calix-NH2-PMO (Ln = Eu, Tb; Calix-NH2 = 5-氨基-25,26,27,28-四羟基杯[4]芳烃, PMO =通过共价键组装方法将 Ln3+ 和 2,2'-联吡啶 (bpy) 引入到 Calix-NH2-PMO 杂化材料中组装而成。 FTIR、UV、SAXRD、TEM、N2 吸附测量、光致发光光谱和热重图，结果表明所得材料具有高比表面积、介观结构均匀性和良好的结晶度。此外，与二元介孔杂化物Ln-Calix-NH2-PMO相比，三元介孔杂化物bpy-Ln-Calix-NH2-PMO在发光强度、发光寿命和量子效率方面均表现出整体提高，这表明引入第二配体2,2'-联吡啶可以敏化镧系离子的发光发射。 bpy-Ln-Calix-NH2-PMO 的热重分析表明，由于共价键合到 PMO 基体上，镧系配合物的热稳定性明显提高。

  Novel luminescent ternary organic–inorganic mesoprous hybrid materials bpy-Ln-Calix-NH2-PMO (Ln = Eu, Tb; Calix-NH2 = 5-amino-25,26,27,28-tetrahydroxycalix[4]arene, and PMO = periodic mesoporous organosilica) have been assembled by introducing Ln3+ and 2,2′-bipyridine (bpy) into the Calix-NH2-PMO hybrid material through a covalent bond assembling method. FTIR, UV, SAXRD, TEM, N2 adsorption measurements, photoluminescent spectra, and TG plots were obtained, and the results reveal that the resulting materials have high surface area, uniformity in the mesostructure, and good crystallinity. In addition, compared with the binary mesoporous hybrid Ln-Calix-NH2-PMO, the ternary mesoporous hybrids bpy-Ln-Calix-NH2-PMO show an overall increase in luminescent intensity, luminescent lifetime and quantum efficiency, which indicates that the introduction of the second ligand 2,2′-bipyridine can sensitize the luminescence emission of the lanthanide ions. Thermogravimetric analysis on bpy-Ln-Calix-NH2-PMO demonstrated that the thermal stability of the lanthanide complex was evidently improved as it was covalently bonded to the PMO matrix.

  of the resulting lanthanide mesoporous hybrids. The photoluminescent behavior (luminescence, lifetime, quantum efficiency, and energy transfer) for these chemically bonded mesoporous hybrids is studied in detail. Also, their quantum efficiencies are determined, which indicates that the different mesoporous hybrid material systems derived from different functionalized calix[4]arene derivative bridges
