I want to synthesize Metal Organic Frameworks . When I mix TPA ,metals and DMF as solvent they don't homogenize and start settling down .
Can you tell me what's the matter ? Either my solvent is not good or any other procedure ?
Dear Hareem,

Dear Hareem Shaukat Awan many thanks for sharing this interesting technical question with the RG community. Metal-organic frameworks (MOFs) are normally / often synthesized by hydrothermal methods, which means that the aqueous reaction mixtures are heated above the boiling point of water. Under these conditions, pressure builds up so that the reactions must be carried out in closed vessels such as metal autoclaves or thick-walled sealed glass tubes. Controlled slow cooling to room temperature eventually provides crystalline MOFs (if you are lucky...). This mean that just mixing the starting materials under normal conditions will usually not yield a MOF right away. In addition to the useful literature references suggested by Francisco Manuel Marquez I strongly suggest that you also use RG directly as a valuable source of information. Just search RG for terms like "MOF synthesis" and then click on "Publications". That way you can find and access very many useful articles (including review articles) which have been posted by RG members, many of them even as public full texts. It might also be useful to check the "Questions" section of RG for closely related questions. Quite often the answers given to such similar questions are also very helpful. Moreover, please note that terephthalic acid (TPA) is one of the most often employed "linkers" in MOF chemistry. Various MOFs containing TPA have already been published and studied in detail. Thus please check the previous literature for articles on TPA-based MOFs.
I hope this helps. Good luck with your work and best wishes, Frank Edelmann
Dear Hareem, there are so many reports on the synthesis of different MOFs in thr literature. Why don't you use one of the reported procedure for synthesizing your MOF?
