Special Issue Information

Dear Colleagues,

Supramolecular chemistry has long since evolved from its original definition more than 30 years ago and has generated new areas of chemistry that have continously been in development. New architectures have been initially created only to express the beauty of chemical diversity. Later, these supramolecular assemblies have steadily found new applications as sensors, receptors, molecular machines, catalysts, smart materials, dynamic biomaterials, etc.

Looking back to the progress of supramolecular chemistry and related materials chemistry fields, it is very likely that supramolecular materials are going to dominate in the future decades. This is because the principles used for their construction operate with simple, yet complex concepts and use easily renewable materials. Moreover, researchers can turn back to small, diverse, and cheap building blocks that are able to yield stable, elaborated structures with unexpected properties and functions.

The synthetic approaches of such supramolecular materials have concomitantly emerged from the desired applications and represent the main interest of many research groups. Structural analysis and investigation methods aimed to unveil a variety of properties have also become available during the past decades and are now commonly used for materials characterisation.

The field of supramolecular materials is coming to its maturity, and we are witnessing its intersection with numerous areas of chemistry, physics, biology and medicine.

We invite all of you working in supramolecular and related fields to share the ultimate experiences that reinforce the idea of functional materials stabilised by non-covalent interactions which can lead to future and immediate innovative applications.

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

Supramolecular chemistry, although focused mainly on noncovalent intermolecular and intramolecular interactions, which are considerably weaker than covalent interactions, can be employed to fabricate sensors with a remarkable affinity for a target analyte. In this review the development of cyclodextrin-based electrochemical sensors is described and discussed. Following a short introduction to the general properties of cyclodextrins and their ability to form inclusion complexes, the cyclodextrin-based sensors are introduced. This includes the combination of cyclodextrins with reduced graphene oxide, carbon nanotubes, conducting polymers, enzymes and aptamers, and electropolymerized cyclodextrin films. The applications of these materials as chiral recognition agents and biosensors and in the electrochemical detection of environmental contaminants, biomolecules and amino acids, drugs and flavonoids are reviewed and compared. Based on the papers reviewed, it is clear that cyclodextrins are promising molecular recognition agents in the creation of electrochemical sensors, chiral sensors, and biosensors. Moreover, they have been combined with a host of materials to enhance the detection of the target analytes. Nevertheless, challenges remain, including the development of more robust methods for the integration of cyclodextrins into the sensing unit. Full article
