Abstract

The surge of photonics as key enabling technology for lighting has driven the search of new chart of modern applied fluorophores. In this line, we recently found that a set of compounds previously synthesized by us and pertaining to the family of benzo[f]indazoles, were able to absorb light and convert it into glow blue fluorescence. Prompted by these findings, we came interested in exploring their viability as versatile fluorophores for bioimaging. To this aim, in this work we present a comprehensive study of the electronic, structural, electrochemical and photophysical properties of this new library of dyes in solution and solid-state under mild and hard irradiation regimes. We intend to understand the molecular structure-photophysics relationship and estimate the strengths and weaknesses of these dyes as potential fluorescent probes for bioimaging or other kind of light-driven applications. One of the main outcome of this study is that the photonic performance of the herein reported benzo[f]indazole-based dyes surpasses coumarines, considering as benchmark in the same spectral window, yielding brighter and long lasting emission even under intense and prolonged illumination.

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
