Special Issue Information

Dear Colleagues,

Polymers and low-molar-mass derivatives, containing electroactive fragments and capable of thin amorphous film formation on the substrate, are used to fabricate functional layers for organic light-emitting diodes (OLEDs), photovoltaic cells, field effect transistors and photorefractive materials. Recent advances in organic optoelectronics, particularly in efficient OLEDs, have called for new electro-active organic materials, as well as for new device technologies. Small OLED-based displays already generate hundreds of millions of dollars. Larger OLED displays will penetrate the television market in the not-too-distant future. Nowadays, white displays play an important role in lighting.

Despite their recent progress, OLEDs and other devices are still dealing with issues of efficient and balanced carrier injection and transportation because of large differences in barrier heights and low carrier mobility. Therefore, new, more effective, compounds are being developed. These compounds have good film-forming properties, high hole mobility in their layers, and photoconductive properties. The ideal material for a device should display good solubility, high thermal stability, good film-forming ability, and high hole mobility in its layer. Hence, materials possessing low ionization potential for efficient hole or electron injection, high mobility, thermal durability, and morphological stability with high glass transition temperatures are still necessary. The efficiency of these devices would be increased several times by using materials with multilayer structures.

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. Coatings is an international peer-reviewed open access monthly 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 2600 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.
