Pyrazoline derivatives have been investigated in many respects due to their blue light emission with high quantum yield [10e14], ready accessibility, and easily being used as carrier transporting as well as emitting materials [15]. Many have been reported as hole transporting or emitting materials in organic EL devices [16e18]. And also it is well known that the naphthalimide usually exhibits strong fluorescent emission on irradiation, which usually acts as supermolecular moieties for the study of photo-induced electron transfer [19,20], fluorescence switcher [21] or liquid crystal displays [22]. Recently, naphthalimide derivatives utilized as EL materials have been reported [23,24], whose fluorescence emission can be widely tuned (from blue to yellow, green and even red) with aminoand alkoxy-groups at the 4-position of naphthalimide. Many multichromophore compounds have been synthesized [9,25]. Our group has previously reported the synthesis of several benzothiazoyl pyrazoline derivatives containing aromatic heterocycle, which have good blue fluorescence. In this paper, we synthesized a series of novel bischromophore compounds containing pyrazoline and naphthalimide groups using 4-hydrazinenaphthalimides and chalcones (Scheme 1), which had good green light fluorescence. These bischromophore compounds have seldom been reported previously. |

由于喹唑啉的蓝光发射具有高量子效率，良好辅助功能，并且很容易被用作发光材料的载体运输，所以吡唑啉衍生物在很多方面都有对其进行研究 [15]. 据报导，孔运送或有机发光材料都是喹唑啉的材料[16e18]。 萘通常会显示出强荧光发射放射，通常用于超分子亚胺光诱导电子转移的研究[19,20], 荧光切换器[21] 或者液晶显示器[22] 。最近报导，萘衍生物烷氧基在萘 4 位上被用作EL 材料 [23,24], 它的荧光发射范围很宽 （从蓝黄色、 绿色、 甚至到红色） 。许多此类化合物已经合成[9,25]. 我们课题组先前已经报导了几个含芳香杂环的苯并噻唑吡唑啉衍生物的合成，其中有好的蓝色荧光。在本文中，我们合成了一系列新型 双氯类化合物，它包含吡唑啉和4位取代的萘以及查尔酮 (表 1)，会发出绿色荧光。以前这些双氯类化合物很少报导。 |
