Conjugated Polymer Materials for Emerging Electronic Device Applications

Dear Colleagues,

In 1977, Shirakawa, MacDiarmid, and Heeger were the first to report a conducting polymer, namely polyacetylene doped with halogen ions or arsenic pentafluoride, for which they won the Nobel Prize in Chemistry in 2000. Since then, π-conjugated polymers have attracted extensive interest for applications in noble optoelectronic devices owing to their mechanical flexibility, optoelectronic tunability, and potentially low-cost manufacturing using graphic arts printing techniques. Recently, a polymer semiconductor-based light-emitting diode (PLED) produced using inkjet printing came close to commercialization. Polymer semiconductor-based organic field-effect transistors (OFETs) and their applications in various electronic sensors, as well as polymer-based energy harvesting devices, such as organic photovoltaic cells (OPVs) and thermoelectric devices, are emerging as next-generation electronic devices.

This Special Issue is focused on the optoelectronic applications of π-conjugated molecule-based semiconductor materials. Topics may cover the design and synthesis of π-conjugated molecules for emerging optoelectronic applications, π-conjugated organic semiconductor-based electronic devices including OLED, OPV, and OFETs, and their optimized fabrication process. The issue may also address the structure–properties relationship, electronic structures, charge generation and annihilation phenomena, or charge-transporting mechanisms in π-conjugated molecules, which will help to compile the current state of the art and to highlight their range of applications. Both original contributions and reviews are welcome.

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 250 words) can be sent to the Editorial Office for assessment.

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. Polymers 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.
