1,8-Naphthalimide Derivatives as Signal Elements in Chemical Sensors

Dear Colleagues,

In recent years, the field of chemical sensors has seen significant growth due to the development of various sensor materials that feature high sensitivity, selectivity, and stability. Among these materials, 1,8-naphthalamide derivatives have gained popularity as versatile signal elements in chemical sensor design and construction due to their unique photophysical properties, structural flexibility, photostability, and ease of functionalization. On the other hand, by varying the electron donor substituent spatiality on the C-4 atom, compounds emitting blue wavelengths and yellow-green fluorescence with different intensities can be obtained.

1,8-Naphthalamides, as signal elements, offer several advantages, including a strong fluorescence, large Stokes shifts, and excellent photostability, which make them ideal for the design and fabrication of a wide range of optical sensors. These sensors find applications in environmental monitoring, industrial processes, medical diagnostics, and biological imaging. In addition, 1,8-naphthalamides can be designed to respond to specific analytes, such as metal ions, anions, pH changes, and biomolecules, enabling the creation of highly selective sensors.

This Special Issue seeks original research papers and review articles that address the design, synthesis, and application of chemical sensors based on 1,8-naphthalamides as signal units.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors 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 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.
