Synthesis of MOF having functional side group

Synthesis of Zn-MOF incorporating titanium-hydrides as active sites binding H2 molecules

“…3 was stored in a glove box purged with Ar gas (99.999 %). The successful synthesis of 1, 2, and, 3 was confirmed by 1 H-NMR and differential scanning calorimetry (DSC) under a N 2 atmosphere (30 mL min -1 ) showing distinguishable melting point of each chemical [10][11][12].…”

“…S1) [10][11][12]. First, 10.2 mmol (1.69 g) of benzene-1,4-diboronic acid, 20.4 mmol (4.99 g) of methyl 4-bromo-3-methoxybenzoate, and 0.6 mmol (0.69 g) of Pd(PPh 3 ) 4 were slowly added to a mixed solution of THF (80 mL) and K 2 CO 3 (15 ml, 2 M dissolved in deionized water) at 80 °C.…”

“…HCC-1 was solvothermally synthesized based on the procedure we previously reported [10][11][12]. For the synthesis of HCC-1, 1.25 mmol (0.44 g) of di-OH-TPDC and 7.50 mmol (2.23 g) of Zn(NO 3 ) 2 •6H 2 O were dissolved in 200 ml of DMF.…”

“…This PSM to yield HCC-1/Ti(Cy) 3 was conducted following a slightly modified procedure we suggested previously [10][11][12]. In a bottle, 0.68 mmol (0.26 g) of Ti(Cy) 4 [30] dissolved in 50 mL of dry toluene was added to 0.1 g of HCC-1 with -OH functionality of 4.68 mmol g -1 inside the globe box at -30 °C.…”

“…In particular, the structures of Zn-based MOFs (ZnMOFs) have been controlled by varying organic struts coordinated to Zn nodes while providing a variety of free functionalities (-OH [10][11][12], -NH 2 [13], -CHO [14], and -CN [15]). This renders the use of Zn-MOFs as reactive supports since these functionalities were post-synthetically modified using organic/inorganic precursors to provide properties beneficial for the target applications [16,17].…”
