Abstract: The present invention discloses a phenanthrene derivative having the following structure: wherein Ar1 and Ar2 independently are phenyl, nathphyl, heterocyclic group, polycyclic aromatic or polycyclic heterocyclic group with at least one conjugated substituent. The conjugated substituent can be an electron withdrawing group or electron donating group. The phenanthrene derivatives have semiconductor properties of electron transfer, electroluminescence (EL), and photoluminescence (PL). Intermolecular stacking can be avoided and electron-luminescent emission stability is enhanced when the derivatives are applied as a light-emitting material in organic EL devices due to the presence of the two stereo cyclopentane rings, such as a host compound or a dopant emitting blue light.

Abstract: A liquid-control optical element is provided herein. The optical element includes two liquids with different phases. The two liquids are immiscible and have different optical index. By applying a voltage through electrodes to form an electric field, the slope of an interface between the two liquids is changed. The purpose of changing the slope is to change the shape of the interface or the moving or rotating direction. Thus, according to the law of total internal reflection or the law of refraction, the liquid-control optical element can be used as a liquid shutter device, or a liquid scanner device if a scanning is performed after penetrating the element.
