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. |
