Special Issue Information
Dear Colleagues,
Luminescence is an important physical phenomenon, without which the operation and even existence of many electronic devices would be impossible. Coordination compounds include a central ion and ligands (neutral molecules or anions) linked to it by the coordination bonds. By combining metal ions with ligands of different natures, one can tune the luminescent properties of the resulting coordination compounds. Knowledge of the crystal structure of metal complexes makes it possible to study the dependencies of the luminescent properties of compounds on their structure, which is important for the rational synthesis of coordination compounds with desired photophysical properties. Various luminescence mechanisms can be realized in coordination compounds: metal-centered luminescence, as in lanthanide complexes, metal-to-ligand charge transfer (MLCT) and ligand-to-metal (LMCT) charge transfer in transition metal compounds. Intraligand luminescence is also possible, in which the organic ligand is the carrier of luminescent properties, while the metal ion plays a structure-directing role. Of great importance are more complex examples of photophysical properties, such as thermally activated delayed fluorescence (TADF), excitation wavelength-dependent emission, and multi-band emission. In addition to photoluminescence, which occurs under the action of light, electroluminescence and triboluminescence play an important role. In recent years, more and more attention is paid to stimuli-responsive luminescence, when the photophysical properties of the material can be controlled by the external physical or chemical stimuli, such as temperature, pressure, electromagnetic radiation, pH of the medium, or the presence of certain compounds.
The topics of this issue include, but are not limited to:
- Synthesis and crystal structure of new luminescent metal complexes and coordination polymers;
- Study of structure–property relationships for the photophysical properties of coordination compounds;
- Coordination compounds demonstrating solvo- or vaporchromism of luminescence;
- Stimuli-responsive luminescence of coordination compounds;
- Sensing applications of luminescent coordination compounds.
Submissions in the form of Research papers, Communications or Reviews are anticipated.

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.
