Special Issue Information

Dear Colleagues,

As is well known, noble metals (NMs) represent global valuable and strategical assets and play a critical role in a wide range of conventional (i.e., jewelry, coins, bio-medicine) as well as high-tech fields (i.e., electric and electronic equipment, catalysis, pharmaceuticals, photonics). Specifically speaking about optical applications, NM complexes have largely been demonstrated to behave, when properly designed, as photoactive moieties where light-induced functions can be tuned and controlled by modification of the ligands with an impact on electron and energy transfer processes addressed at molecular switching, signaling, and energetics. The high quest of NMs coupled with the increasing risk of shortage in the supply, both for depletion of natural resources and governance and trade aspects of suppliers, make these metals critical elements and their recovery from scraps highly appealing for economic and environmental purposes. In this framework, this Special Issue of Molecules is devoted to collecting valued contributions on: i) sustainability in NM recovery and recycling via waste enhancement to secondary resources addressed at circular economy models, and ii) molecular engineering of NM complexes to achieve linear and nonlinear optical and stimuli-responsive properties. All scientists working in these fields are warmly invited to submit their works for publication in this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at 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 papers will be 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 2000 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.
