Abstract

A Cu-based metal-organic framework (HKUST-1 or Cu3(BTC)2, BTC = 1,3,5-benzene tricarboxylate) has been synthesized from insoluble Cu-based precursors and positioned on substrates. Patterning of HKUST-1 was achieved through a two-step process: (1) the positioning of the insoluble Cu-based ceramic precursors on substrates using a sol-gel solution, and (2) the subsequent conversion into HKUST-1 by treatments with an alcoholic solution containing 1,3,5-benzene tricarboxylic acid (H3BTC) at room temperature for 10 min. This technique has been found to be suitable for both inorganic and polymeric substrates. The HKUST-1 pattern on a polymer film can be easily bent without affecting the positioned MOFs crystals. This approach would allow for versatile and practical applications of MOFs in multifunctional platforms where the positioning of MOFs is required.
