Amino substituted Cu3(btc)2: a new metal–organic framework with a versatile functionality

Abstract

A new amino substituted tricarboxylate linker and the new metal-organic framework Cu(3)(NH(2)btc)(2) have been synthesised. The new MOF shows good adsorption properties and is suitable for postsynthetic modification to form an amide functionalised framework.

Mapping the Cu-BTC metal–organic framework (HKUST-1) stability envelope in the presence of water vapour for CO2 adsorption from flue gases

“…copper benzene-1,3,5-tricarboxylate or HKUST-1 [11], is one of the most extensively studied MOFs for gas separation [12][13][14][15] and storage [16,17] due to its high surface area (normally in a range of 600-1600 m 2 g À1 for samples synthesised in a laboratory), large pore volume (ca. 0.70 cm 3 g À1 ) [18] and good thermal stability (thermally stable up to 350°C) [19].…”

“…To date, the primary research interest of CO 2 adsorption on HKUST-1 has been focused on the manipulation of the CO 2 adsorption capacity/selectivity by using materials design strategies [17,26] or postsynthetic modification approaches [15]. However, apart from tuning the CO 2 /N 2 selectivity to increase the CO 2 capture efficiency, the effect of the presence of water vapour in flue gas streams also needs to be considered to properly assess their performance as potential CO 2 capture materials.…”

Tuning the nitric oxide release behavior of amino functionalized HKUST-1

“…2). All MOFs are isostructural with HKUST-1 and UHM-30 [35] e the primary amino functionalized HKUST-1. We show how the amine groups influence the NO storage capacity and release performance of these MOFs.…”

Functional group tolerance in BTB-based metal–organic frameworks (BTB – benzene-1,3,5-tribenzoate)

“…In order to incorporate amino-modified biphenyldicarboxylate (NH 2 -BPDC) into the corresponding IRMOF-9, the amino function had to be protected with a tert-butyloxycarbonyl (Boc) protecting group [19]. Amino-functionalized benzene tricarboxylic acid (H 3 (NH 2 -BTC)) was synthesized by Fr€ oba and coworkers with further successful utilization in the synthesis of an HKUST-1 analog [20].…”
