Special Issue Information

Dear Colleagues,

In recent years, new organic semiconducting materials have been rapidly developed for use in practical applications, e.g., light-emitting devices, solar cells, transistors, and detectors.

The present Special Issue intends to highlight the results of experimental and theoretical investigations into the emerging organic optoelectronic materials, with extension to organic/inorganic hybrid materials, particularly related to state-of-the-art quantum dots and perovskite families. This issue mainly covers light/electricity generation and harvesting mechanisms, based on structure–property relationships. Broad aspects of this topic will be compiled, such as the synthesis of new materials, morphological control, photophysical characterization, defect passivation, thin-film growth, and optical manipulation.

Original manuscripts (full-length articles, reviews, communications, etc.) highlighting results from experimental and theoretical investigations with reference to emerging materials for light-to-electricity or electricity-to-light conversion are all 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 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 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.

Blue exciplexes, a critical innovative component in organic light-emitting diodes (OLEDs) technology, exhibit substantial potential for enhancing device efficiency, reducing driving voltage, and simplifying structural designs. This article reviews the pivotal role of blue exciplexes in OLEDs, analyzing their unique advantages and challenges as emitters and host materials. Through optimized molecular design, blue exciplexes achieve high color purity and emission efficiency, surpassing conventional fluorescent materials. Additionally, their wide energy bands and high triplet energy provide opportunities to improve the performance of sky-blue, deep-blue, and white OLEDs. However, limitations in deep-blue efficiency, material degradation due to high-energy excitons, and spectral red-shift pose significant challenges to their development. This review offers a comprehensive perspective and research reference on the photophysical mechanisms of blue exciplexes and their applications in display and lighting fields. Full article
