Special Issue Information

Dear Colleagues,

The 21st National Symposium on Macrocyclic Chemistry and 13th National Symposium on Supramolecular Chemistry will be held at Tianjin Normal University in August (15–18), 2023. This conference is an internationally recognized symposium held every two years in different cities of China, aiming to promote the cross and penetration of macrocyclic chemistry and supramolecular chemistry in the fields of materials, pharmacy, biology, medicine and other disciplines, and create an important platform for experts and scholars engaged in macrocyclic chemistry and supramolecular chemistry to exchange research results, to contribute to the sustainable development of chemistry-related fields.

The Scientific Committee would like to invite scientists with expertise in macrocyclic chemistry, molecular devices and molecular machines, molecular self-assembly and assembly, rotaxanes and pseudorotaxanes, supramolecular polymers, soft matter, optoelectronic materials and devices, chemical and biosensors to submit an article to this Special Issue of the journal Molecules. Three types of contributions will be considered: (i) research articles; (ii) communications; and (iii) reviews.

Prof. Dr. Chunju Li
Guest Editor

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. 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.

Research on stimuli-responsive host–guest systems is at the cutting edge of supramolecular chemistry, owing to their numerous potential applications such as catalysis, molecular machines, and drug delivery. Herein, we present a multi-responsive host–guest system comprising azo-macrocycle 1 and 4,4′-bipyridinium salt G1 for pH-, photo-, and cation- responsiveness. Previously, we reported a novel hydrogen-bonded azo-macrocycle 1. The size of this host can be controlled through light-induced E↔Z photo-isomerization of the constituent azo-benzenes. The host is found in this work to be capable of forming stable complexes with bipyridinium/pyridinium salts, and implementing guest capture and release with G1 under light in a controlled manner. The binding and release of the guest in the complexes can also be easily controlled reversibly by using acid and base. Moreover, the cation competition-induced dissociation of the complex 1a2G1 is achieved. These findings are expected to be useful in regulating encapsulation for sophisticated supramolecular systems.
