Product Description:

Trans-Stilbene is an organic compound characterized by a central trans-configured carbon-carbon double bond linking two phenyl groups. It is a colorless to pale yellow crystalline solid with a melting point of 124-125 °C. It is a classic example of a stilbene derivative. Its primary industrial and research significance lies in the field of optoelectronics. trans-Stilbene is a fundamental building block and a key precursor for synthesizing advanced organic light-emitting diode (OLED) materials, fluorescent dyes, and laser dyes. It serves as the core structure for numerous compounds used in organic semiconductors due to its excellent photophysical properties, including strong fluorescence and efficient energy transfer. It is also widely used as a scintillator material for radiation detection. Beyond its material applications, trans-stilbene is a versatile and common organic synthesis intermediate. It is frequently employed in organic chemistry as a model substrate for studying photoisomerization reactions (conversion to cis-stilbene) and various cycloaddition reactions, making it a standard reagent in research laboratories.
