Synthesis and Color-tunable Fluorescence Properties of Schiff Base Zinc (II) Complexes Used as Electroluminescent Materials

Four kinds of bis(N-alkylsalicylaldiminato) zinc(II) complexes were synthesized, and their molecular structures were determined by FT-IR and elemental analysis. Their photoluminescence properties were determined, which indicated that they could emit strong fluorescence varying from blue to yellow to reddish orange depending on their different molecular structures. They had good thermostability, solubility and film forming capability, and can be used as organic lectroluminescent materials. These new complexes may afford the feasibility to realize full-color display with materials based on similar molecular structures.

Synthesis of Pyrazolines Used as Blue Organic Electroluminescence Materials

Three kinds of pyrazolines were designed and synthesized. Their structures were elucidated by IR, (HNMR)-H-1, MS, UV and elemental analysis. Their luminescent properties were determined, which indicated that they had strong blue fluorescent properties. One of them was designed to have good film formation. All the three kinds of pyrazolines can be used as blue organic electroluminescence materials (OELMs).

Synthesis of a Novel Blue- light- emitting Polymer Material Bearing Coumarin Pendants

A novel blue luminescent polymer bearing coumarin pendants was prepared. Its luminescent properties were determined indicating that it had strong blue fluorescent properties and good film formation ability. This novel polymer can be used as a blue organic electroluminescent material (OELM) in organic electroluminescent devices.

Synthesis of a New Family of Green Light Emitting Material Containing Both Hole and Electron Transporting Units

Two new molecules containing oxadiazoles and triphenylamine-stilbene moiety were synthesized. Their luminescent properties were determined, which indicated that they had strong green fluorescent properties. All the two molecules can be used as green organic electroluminescence materials.

Synthesis of Two Blue-light emitting Complexes with Schiff Base Calixarene as the Ligand

Two new blue luminescent zinc and beryllium complexes with Schiff base calixarene derivative as the ligand were prepared. Their luminescent properties were determined, which indicated that they had strong blue fluorescent properties. They also had good solubility and film formation. These new complexes can be used as blue organic electroluminescent materials (OELMs) in organic electroluminescent devices.
