Used as a key intermediate in the synthesis of advanced organic materials, particularly in the development of photochromic and electrochromic compounds. Its unique conjugated structure makes it suitable for applications in optoelectronic devices such as organic light-emitting diodes (OLEDs) and molecular switches. Also employed in the design of fluorescent sensors due to its strong emission properties and sensitivity to environmental changes. Additionally, it serves as a building block in the creation of nonlinear optical (NLO) materials for use in laser technology and signal processing.
