Special Issue Information
Dear Colleagues,
The excessive volume of produced plastics with various origins present today means that we are increasingly faced with the problem of environmental pollution, which is growing at an incredible pace. This creates the need to search for novel materials that can replace those currently employed by humans, and simultaneously find materials that have comparable or enhanced photophysical and physicochemical properties. Among the most promising materials are polymer derivatives, which have been modified with additives of natural origin to become biopolymers. As is evident in the data found in the latest literature, newly obtained materials often have far superior physicochemical and other properties compared to previously utilized materials. This creates new methods for their development and application in practically every area of human life. We can utilize them in new biodegradable packaging, reflective materials, surface protection materials and UV absorbers, among others.
The latest publication trends show an elevated interest in polymeric and biopolymer materials, with the addition of various molecules. The additives employed can significantly alter the photophysical or physicochemical properties of the obtained materials, thus dramatically increasing their applicative potential. The development of modern spectroscopic techniques, particularly fluorescence, provides us with a significant opportunity to explore the research topic.
Understanding the molecular mechanisms that enhance their properties offers an extraordinary opportunity to solve the escalating issues caused by the production of materials that are difficult to recycle and pollute our environment uncontrollably. Closing any molecule in the biopolymer system facilitates the access of molecules to triplet states, which launches a new emission route and thus promotes the novel application of known materials.
This Special Issue is primarily dedicated to topics related to the application of polymers and biopolymers modified with the addition of various compounds, both known and newly synthesized.
We are particularly interested in the fluorescent and phosphorescent effects of molecules enclosed in rigid polymer matrices. Enclosed molecules in a rigid polymer/biopolymer matrix possess properties that are unattainable in solvent systems or aqueous solutions, and this is of particular interest to us. We strongly encourage you to submit papers related to the above-mentioned topics in combination with the utilization of nanoparticles and other modern materials.
We are particularly interested in the effects of room-temperature phosphorescence (RTP) emission. In this Special Issue, we welcome original papers on the described subject and review papers summarizing achievements in the field so far; papers that present spectroscopic methods at the most basic to the most advanced level; DFT, [TD]DFT and crystallographic results supported by calculations in the field of quantum chemistry; and the results of biological tests on the molecules placed in biofilms in the domain of antifungal activity. We support works in which the authors try to combine several spectroscopic properties of the obtained system and present an interesting theoretical discussion. Therefore, we encourage you to submit experimental spectroscopic, theoretical and biological papers in this field.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
