Special Issue Information

Dear Colleagues,

Polyelectrolytes constitute a broad group of compounds, which, depending on their origin, are divided into natural polyelectrolytes, synthetic polyelectrolytes, and chemically modified biopolymers. The ease of creating polyelectrolyte complexes (PECs) and the possibility of introducing various modifiers into them mean that there is enormous potential for obtaining systems with the desired composition and architecture. Obtaining functional materials with strictly controlled properties is extremely important for their application and constitutes the basis of modern nanotechnologies. The primary goal is to understand and quantitatively describe the fundamental laws and phenomena that determine the properties of such materials. PECs show huge potential for application in biotechnology, medicine, pharmacy, and environmental protection, among other areas.

This Special Issue, “Polyelectrolytes and Polyelectrolyte Complexes: Ionic Macromolecule-Based Functional Materials”, will present publications that show the spectrum of applications of materials based on polyelectrolyte systems, including correlations showing the close relationship between the composition and properties of the obtained materials.

Interdisciplinary publications covering experimental methods and simulations that identify the physicochemical properties of polyelectrolyte systems to control their function and structure at the molecular level are welcome.

We will accept full articles and reviews presenting significant and recent achievements in using polyelectrolytes and analyses of their structure, properties, and applications.

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.

We synthesized novel polyelectrolytes based on naphthalene diimide with quaternary amine featuring hydroxyl groups at the side chain, along with different counteranions (PF-NDIN-Br-OH and PF-NDIN-I-OH) for polymer solar cell (PSC) application as the interlayer. The polyelectrolytes establish a beneficial interface dipole through the ionic moieties and synergistic effects arising from the hydroxyl groups located at the side chain. Incorporating polyelectrolytes as the cathode interlayer resulted in an enhancement of the power conversion efficiency (PCE). The PCE of the device with PF-NDIN-Br-OH increased from 8.96% to 9.51% compared to the ZnO-only device. The best PCE was obtained with the device based on PF-NDIN-I-OH, up to 9.59% resulting from the Jsc enhancement. This outcome implies a correlation between the performance of the device and the synergistic effects observed in polyelectrolytes containing hydroxyl groups in the side chain, along with larger anions when employed in PSCs.
