Special Issue Information

Dear Colleagues,

In recent years, metal–organic frameworks (MOFs) have been recognized as an emerging class of crystalline porous materials and attracted tremendous interest. Numerous MOFs have been developed and found to be promising materials in a wide variety of fields because of their structural, textural, and functional diversity and tunability. Current trends in MOF research have mostly focused on finding a way to use MOFs or MOF-related materials in real-world applications. There are different kinds of devices/systems, such as gas storage/separation, adsorption in polar/non-polar media, molecular sensing, drag storage/delivery, and catalysis, developed using MOF-related materials. Moreover, the performance or new functionalities may be added to a MOF structure via suitable incorporation of secondary metals or ligands to obtain MOFs with bi-metals and bi-ligands, respectively. Moreover, MOFs are very promising materials for composites with other materials, utilizing their pore spaces and metal/ligand sites, which generally result in better functionality in various applications. In addition, MOFs including pristine, bimetallic, and composites are often used as a precursor to obtain fascinating nanohybrid carbon materials with impressive results in adsorption, catalysis, storage/separations, sensing, etc.

This Special Issue on “Current Trends in the Metal–Organic Framework for Environment and Catalysis” welcomes original scientific research articles, comprehensive reviews, and communications in relevant research areas focusing on the design, synthesis, post-modification, and characterization of MOFs (pristine, bimetallic, and composites) and their derived carbons for environmental remediation through adsorption, storage/separation, catalysis, and sensing.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Two Cd(II) based coordination polymers, {Cd3(btc)2(BTD-bpy)2]∙1.5MeOH∙4H2O}n (1) and [Cd2(1,4-ndc)2(BTD-bpy)2]n (2), where BTD-bpy = bis(pyridin-4-yl)benzothiadiazole, btc = benzene-1,3,5-tricarboxylate, and 1,4-ndc = naphthalene-1,4-dicarboxylate, were hydro(solvo)thermally [...] Read more.
Two Cd(II) based coordination polymers, {Cd3(btc)2(BTD-bpy)2]∙1.5MeOH∙4H2O}n (1) and [Cd2(1,4-ndc)2(BTD-bpy)2]n (2), where BTD-bpy = bis(pyridin-4-yl)benzothiadiazole, btc = benzene-1,3,5-tricarboxylate, and 1,4-ndc = naphthalene-1,4-dicarboxylate, were hydro(solvo)thermally synthesized. Compound 1 has a three-dimensional non-interpenetrating pillared-bilayer open framework with sufficient free voids of 25.1%, which is simplified to show a topological (4,6,8)-connected net with the point symbol of (324256)(344454628)(3442619728). Compound 2 has a three-dimensional two-fold interpenetrating bipillared-layer condense framework regarded as a 6-connected primitive cubic (pcu) net topology. Compounds 1 and 2 both exhibited good water stability and high thermal stability approaching 350 °C. Upon excitation, compounds 1 and 2 both emitted blue light fluorescence at 471 and 479 nm, respectively, in solid state and at 457 and 446 nm, respectively, in the suspension phase of H2O. Moreover, compounds 1 and 2 in the suspension phase of H2O both exhibited a fluorescence quenching effect in sensing Ag+, attributed to framework collapse, and a fluorescence enhancement response in sensing Al3+ and Cr3+, ascribed to weak ion–framework interactions, with high selectivity and sensitivity and low detection limit.
