Special Issue Information

Dear Colleagues,

Following a very successful first run, we are pleased to announce the launch of a second edition of a Special Issue on the synthesis and application of metal–organic frameworks, instigated by the still wide applicability of MOFs in analytical science as materials with exceptional properties and advantages. As such, we are inviting authors to present their experience with regard to MOFs’ use.

Metal–organic frameworks (MOFs) are among the most promising novel materials. They belong to a new class of crystalline materials that consist of a coordination bond between metal clusters (e.g., metal–carboxylate clusters and metal–azolate clusters), metal atoms, or rod-shaped clusters and multidentate organic linkers that contain oxygen or nitrogen donors (carboxylates, azoles, nitriles, etc.), thus forming a three-dimensional structure.

The properties of both metal ions and linkers determine the physical properties of MOF networks (e.g., porosity, pore size, and pore surface). Additionally, the structural properties of the prepared frameworks can be controlled by the solvent system, pH, metal–ligand ratio, and temperature.

The concept of MOFs was first introduced in 1990. They were initially used in catalysis, gas separation, membranes, and electrochemical sensors. Later on, they were introduced as SPE (solid phase extraction) sorbents for PAHs (polycyclic aromatic hydrocarbons) in environmental water samples, then the range expanded to the field of analytical chemistry, both in chromatographic separation and sample preparation, with great success in, e.g., SPE and SPME (solid phase mico-extraction). Since then, the number of analytical applications implementing MOFs as sorbents in sorptive sample preparation approaches has been steadily increasing. Τhis is reinforced by the fact that, at least theoretically, an infinite number of structures can be designed and synthesized, thus making tuneability one of the most unique characteristics of MOF materials. Moreover, they have been designed in various shapes, such as columns, fibers, and films, so that they can meet more analytical challenges with improved analytical features.

Their exceptional properties have attracted the interest of analytical chemists who have taken advantage of their unique structures and properties and have already introduced them in several sample pretreatment techniques, such as solid phase extraction, dispersive SPE, magnetic solid phase extraction, solid phase microextraction, stir bar sorptive extraction, etc.

This Special Issue aims to present recent developmentts in the synthesis and applications of MOFs.

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. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). 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
Detection of nitro pollutants is an important topic in environmental protection. A total of 3 Cd (II) complexes (13) based on 3 soft organic isomers, n-(3,5-dicarboxylato benzyloxy) benzoic acid (n = 2, 3 or 4-H3DBB), and [...] Read more.
Detection of nitro pollutants is an important topic in environmental protection. A total of 3 Cd (II) complexes (13) based on 3 soft organic isomers, n-(3,5-dicarboxylato benzyloxy) benzoic acid (n = 2, 3 or 4-H3DBB), and a linear N-donor ligand, 3-bis(imidazole-l-ylmethyl) benzene (3-bibz), have been synthesized hydrothermally. Structural diversity of Complexes 13 displays the architectural 2D or 3D change: Complex 1 exhibits a 2D network featuring tri-nuclear metal units, Complex 2 is a 3D framework based on similar tri-nuclear metal units, and Complex 3 shows a 3D network with binuclear units. Fluorescent sensing properties exhibited in all these complexes have been discovered to detect nitrobenzene (NB) selectively and sensitively. In particular, Complex 3 possesses high sensitivity for NB with the lowest detection limit of 1.15 × 10−10 M. The results of the theoretical calculation verified the fluorescence detection mechanism of NB by these Cd-based complexes. Therefore, these Cd-based complexes might be used as excellent luminescent sensors for NB. Full article
