NH2-MIL-125（Ti）的性质

NH₂-MIL-125(Ti), AYRSORB™ T125金属有机框架（MOF）材料—由一个重复的单元组成。该单元电池由六个接头（配体）和一个金属簇组成。连接器通过将金属簇连接在一起，形成一个多孔网络，该金属簇被称为MOF。为了阐明图1中的结构，用其元素成分说明了群集，以帮助分析师匹配结构与其公式，如下所示。

• CAS＃1309760-94-8
• Formula: C₄₈H₃₄N₆O₃₆Ti₈
• Formula Weight: 1653.74
• Color and Form: Yellow powder
• Available Sizes: 250 mg, 1 g

隔离实心表示的MIL-125（Ti）-NH₂

Using a suitable choice of solvent mixtures (methanol and dimethylformamide (DMF), solid denoted Ti₈O₈(OH)₄(2OC-NH₂-C₆H₃-co₂)₆·18（CH₃哦）·3（ch₃)₂NCHO) or MIL-125(Ti)-NH₂has been separated (MIL is the acronym for Material from Institute Lavoisier). The synthesized solid was heated under vacuum at 200°C for 6 hours to remove the solvent molecules (see Thermogravimetric analysis in Figure 2).

Figure 2.Thermogravimetric analysis

MIL-125-NH₂is thermally powerful. X-ray diffractometry (Figure 3) does not signify any variation in crystallinity after the departure of the guest molecules at less than 200 °C.

Figure 3.

Nitrogen sorption experiments show thatMIL-125-NH₂is a highly porous property of microporous solids, a micropore volume (Vp) of 0.74(2) cm³·g^-1，一个BET表面积为1530 m²·g^-1（图4）。

Activation Protocol

This material can be activated by heating at 200 °C for 6 hours under vacuum. Upon cooling under vacuum, the activated product must be stored and handled in an inert atmosphere.
