Abstract:

Benzothiadiazole (BTD) is one of the most important classes of conjugated systems because of their photophysical properties such as high extinction coefficient, intense fluorescence, and large Stokes shift. These features make them useful in a variety of applications such as optical materials and chemosensors. Fluorescent BTD derivatives are used in practical applications, including their utility as laser dyes, emitters in light-emitting diodes, photoconductors, optical data storage, and optical switches. Imidazolium salts have advantageous physicochemical properties, which can be modulated by the use of different cations and anions. In this work we are interested to explore a straightforward synthesis of a new class of luminescent imidazolum salts derived from imidazole-BTD as starting material.
