Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your research (communications/articles) and/or reviews to Molecules’ Special Issue on “Chemiluminescence and Photoluminescence of Advanced Compounds”.

Luminescence is a fascinating phenomenon regarding the formation of molecules in the electronically excited state, which then emit radiation, returning to the ground state. For the recent two decades, the compounds expressing luminescent properties have found many applications—especially in biomedical, chemical, and environmental analyses—as luminescent indicators or luminescent label fragments. Interest in the use of techniques utilizing luminescence is also increasing in laser technology and optoelectronic devices. They routinely offer superior sensitivity and simplicity at relatively low costs, often without the need for the use of complex optical systems. The search for novel luminescent compounds characterized by a high efficiency and easily tailorable dynamics of light emission, stability in solutions, and solid states is a priority for the applications of luminescent compounds. Therefore, the prospects for the use of luminescent compounds in biological and environmental systems, biotechnology, and material technologies are widespread and growing.

This Special Issue, titled “Chemiluminescence and Photoluminescence of Advanced Compounds”, is devoted to the collection of up-to-date original and review papers in this fast-growing field. In the original articles, both experimental and computational research on the design, synthesis, luminescent properties, mechanism of light generation, application prospects, and other aspects are welcome. Through this Special Issue, we hope to inspire others to gain an interest in luminescence and join us on our journey.

Thanks to recent developments in spectrophotometric instruments, the spectra, quantum yields (Φf), and lifetimes (τf) of photoluminescence from organic and inorganic compounds can be readily determined not only in solution but also in the solid state. It is known that naphthalene emits fluorescence in solution, but not in the solid state. In a previous paper, we reported that solid-state emission can be seen from biaryl compounds comprised of chromophores that show no emission in the solid state. In this work, we prepared diphenylnaphthalenes (DPNs), and the spectra and the Φf and τf values of fluorescence were determined in solution and the solid state, as well as the crystallographic features. The 2,6-Diphenylnphthalene (26DPN) showed solid-state emission in the wavelength region for longer than those in solution, while the emission spectra of the others in the solid state were similar to those in solution. The crystal structure of 26DPN belonged to a herringbone motif, whereas those of the others were column-stacked structures. Based on these spectroscopic and crystallographic facts, the relationship between the crystal motif and the emission features in the solid state is discussed. Full article

Indocyanine green (ICG), a near-infrared (NIR) fluorescent dye with unique photoluminescent properties, is a helpful tool in many medical applications. ICG produces fluorescence when excited by NIR light, enabling accurate tissue visualization and real-time imaging. This study investigates the fundamental processes behind ICG’s photoluminescence as well as its present and possible applications in treatments and medical diagnostics. Fluorescence-guided surgery (FGS) has been transformed by ICG’s capacity to visualize tumors, highlight blood flow, and facilitate lymphatic mapping, all of which have improved surgical accuracy and patient outcomes. Furthermore, the fluorescence of the dye is being studied for new therapeutic approaches, like photothermal therapy, in which NIR light can activate ICG to target and destroy cancer cells. We go over the benefits and drawbacks of ICG’s photoluminescent qualities in therapeutic contexts, as well as current studies that focus on improving its effectiveness, security, and adaptability. More precise disease detection, real-time monitoring, and tailored therapy options across a variety of medical specialties are made possible by the ongoing advancement of ICG-based imaging methods and therapies. In the main part of our work, we strive to take into account the latest reports; therefore, we used clinical articles going back to 2020. However, for the sake of the theoretical part, the oldest article used by us is from 1995. Full article
