Used primarily in organic electronics as a key intermediate in the synthesis of fluorescent dyes and optoelectronic materials. Its conjugated structure makes it suitable for applications in organic light-emitting diodes (OLEDs) and as a building block in nonlinear optical materials. Also employed in the development of sensors due to its strong emission properties and environmental sensitivity. Shows potential in photovoltaic devices as a component in dye-sensitized solar cells. Additionally, utilized in research for photochromic and electrochromic systems because of its reversible light-responsive behavior.
