A novel strategy for the functionalization and design of 4-methylene-4H-pyran merocyaninesviaenamination and 1,8-conjugate addition

Abstract

4-Methylene-4H-pyrans are popular merocyanine dyes, but their functionalization is limited by the Knoevenagel condensation with aromatic aldehydes. In this work, we developed a novel approach for the construction of the...

Exploring optical, electrochemical, thermal, and theoretical aspects of simple carbazole-derived organic dyes

“…The electron-deficient nature of barbituric acid and thiobarbituric acid has garnered significant attention in the realm of optoelectronic devices, due to their exceptional photophysical characteristics [ [38] , [39] , [40] ]. Barbituric acid exposed to exhibit high absorbance and emission in the ultraviolet (UV) range.…”
