Problems solved by technology

However, control over their spatial topology at the micro- and nano-levels is still limited and elusive (Stock and Biswas, 2011; Sindoro et al., 2014)

[0126] Materials and methods

[0127] General method: Pass a glass pressure tube through H in piranha solution (7:3 v / v 2 SO 4 / 30%H 2 o 2 ) for 10 minutes and in deionized (DI) water to clean, then dried at 130°C for 12 hours. WARNING: Piranha is a very dangerous oxidizer and should be handled with care using proper personal protection.

[0128] Transmission Electron Microscopy (TEM): TEM imaging was performed using a Philips CM-120 instrument operating at 120 kV equipped with a charge-coupled device camera (2k x 2k Gatan Ultrascan 1000). TEM samples were prepared by placing a 5 μl drop of the reaction mixture on formvar / carbon, 400 mesh Cu grid and sucking off after 10 seconds. Due to the beam sensitivity of the samples, TEM imaging and SAED measurements were performed under low-dose conditions. Elemental analysis was performed using the EDAX EDS system.

[0129] Scanning Electron Microscopy (SEM): SEM measurements were performed at an EHT voltage of 3 kV using HRSEM ...

Abstract

The present invention provides metal-organic materials, more specifically organometallic polymers, comprising polypyridyl organic ligands such as tetrakis(4-(pyridin-4-ylethynyl)phenyl)methane, tetrakis(4-(2-(pyridin-4-yl)vinyl)phenyl)methane,,3,5,7-tetrakis(4-(pyridin-4-ylethynyl)phenyl)adamantane or 1,3,5,7-tetrakis(4-(2-(pyridine-4-yl)vinyl)phenyl) adamantine, and metal ions structurally coordinated with said ligands, and having three-dimensional crystalline micro or sub-micro structure; as well as a method for the preparation thereof. These metal-organic materials are useful as adsorbents in processes for gas adsorption or separation.
