金属-有机骨架（M0 F）是由金属离子或金属簇通过多齿有机配体连接而构成的晶体材料。本文中，我们描述了两种基于Zr的含蒽的MOF的合成和物理性质，这两种MOF由2，6-蒽二甲酸（2，6-ADCA和2，6-MOF）和1，4-蒽二甲酸（1，4-ADCA和1，4-MOF）组装而成。2，6-ADCA类似物形成高度结晶的八面体结构，其与众所周知的UiO-67骨架同构。另一方面，1，4-ADCA配体的掺入导致大的棒状晶体。两种M0 F均表现出基于连接体的发光。利用稳态漫反射光谱、发射光谱和时间相关单光子计数（TCSPC）光谱研究了2，6-MOF和1，4-MOF的激发态性质。的MOFs的物理化学性质进行了比较，在溶液中的相应的配体。
Metal–organic frameworks (MOFs) are crystalline materials constructed from metal ions or clusters, connected by multidentate organic ligands. Herein, we describe the synthesis and photophysical properties of two Zr-based, anthracene-containing MOFs, assembled from 2,6-anthracenedicarboxylic acid (2,6-ADCA and 2,6-MOF) and 1,4-anthracenedicarboxylic acid (1,4-ADCA and 1,4-MOF). The 2,6-ADCA analogue formed a highly crystalline octahedral structure that is isostructural with the well-known UiO-67 frameworks. Incorporation of the 1,4-ADCA ligand, on the other hand, resulted in large rod-shaped crystals. Both MOFs exhibit linker-based luminescence. The excited-state properties of the 2,6-MOF and 1,4-MOF were examined using stead-state diffuse reflectance and emission spectroscopies and time-correlated single photon counting (TCSPC) spectroscopy. The photophysical properties of the MOFs are compared with those of the corresponding ligand in solution.
