Advances in Nonlinear Optical Molecular Materials

Dear Colleagues,

Nonlinear optical materials are crucial for advanced photonic and optoelectronic applications, including high-speed optical communication, laser technology, and integrated photonic devices. This Special Issue will publish innovative research on molecular designs, synthesis strategies, and characterization techniques, with a focus on enhancing NLO efficiency, thermal stability, and processability. Topics of interest include novel π-conjugated systems, donor–acceptor architectures, supramolecular assemblies, and hybrid organic–inorganic composites. Theoretical insights and computational modeling will further bridge the gap between molecular structures and macroscopic NLO performance.

In this Special Issue, we aim to compile manuscripts that highlight cutting-edge research into the design, synthesis, and applications of molecular materials with nonlinear optical (NLO) properties. We invite researchers to submit original research articles, reviews, and short communications that contribute to a deeper understanding and the further development of these fascinating materials.

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. 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.
