摘要：
Fluorine is an essential component of most liquid crystalline materials as they are used in LCD devices. The reasons for this are manifold: fluorination limits the coordination ability to cationic impurities and thus improves reliability of the LCD, it provides a custom-tailored molecular dipole moment with the right orientation, and it can stabilize certain conformations and rigidify flexible alkyl chains.
