4'-Pentyl-4-biphenylcarbonitrile (5CB)

4'-Pentyl-4-biphenylcarbonitrile, commonly known as 5CB, is a type of liquid crystal compound used in display technology. Its molecular structure allows it to change between different physical states when temperature or electric fields vary, making it ideal for liquid crystal displays (LCDs). In these displays, 5CB aligns in a way that controls light passage, enabling images to be formed on screens. Its unique properties—such as fluidity like a liquid but organized molecular structure like a crystal—are essential for creating sharp, responsive visual displays in devices like watches, calculators, and monitors.
