The present invention provides a novel stilbene derivative represented by the general formula (1): ##STR1## wherein R.sup.1 and R.sup.3 represent an alkyl group, an aryl group, an aralkyl group or an alkoxy group which are optionally substituted; and R.sup.2 and R.sup.4 represent a hydrogen atom, an alkyl group or an alkoxy group which are optionally substituted, provided that when the substitution position of R.sup.2 and R.sup.4 is the 4-(para) position, R.sup.2 and R.sup.4 are hydrogen atoms, a method for producing the same and use thereof. The above stilbene derivative (1) is useful as an electric charge transferring material, particularly hole transferring material.
本发明提供了一种由通用公式(1)表示的新型芪衍生物:##STR1## 其中,R.sup.1和R.sup.3代表可选地取代的烷基、芳基、芳烷基或烷氧基;R.sup.2和R.sup.4代表可选地取代的氢原子、烷基或烷氧基,前提是当R.sup.2和R.sup.4的取代位置为4-(对位)位置时,R.sup.2和R.sup.4是氢原子,一种用于生产相同物质的方法及其用途。上述芪衍生物(1)可用作电荷转移材料,特别是空穴转移材料。
