本研究目標主要是將綠光摻雜客體C545T經由化學合成方式，備製為紅光摻雜客體RC545T，並藉由上述兩摻雜物做為對照組和實驗組，分別與綠光發光主體Alq3依據摻雜濃度不同測量其光譜變化，以做為能量轉移之研究。另外同樣以化學合成方法將綠光摻雜客體C545P，備製為新穎紅光摻雜客體RC545P，並測量其材料及光譜特性。
成功合成出紅光摻雜客體RC545T以及新穎紅光摻雜客體RC545P。並在薄膜發光中，可以明確得知：摻雜客體氰側鍵基所產生因摻雜濃度差異而導致混合光譜紅位移。Alq3摻雜紅光客體RC545T的溶液發光效率為9.28，優於市用Alq3:DCJTB溶液發光效率(7.96)，而Alq3摻雜RC545T的能量轉移效率約17.88%( Alq3:DCJTB能量轉移效率為36.72%)。Alq3摻雜紅光客體RC545T的薄膜發光效率為42.3(市用Alq3:DCJTB發光效率為48.9)。Alq3摻雜RC545T最佳比例濃度介於1%~2%之間，而Alq:RC545T薄膜所產生的紅光色純度高於Alq:DCJTB。

The purpose of the research is probing for the cause that red shift of green-host Alq3 is doped by red dopant with concentration increasing. Generally speaking, this phenomenon of red shift is resulted from the excimer that complex formed by the interaction of an excited molecular entity with a ground state partner of the same structure. And that excimer maybe formed by cyaniding group of red dopant because of the molecular polarity. We will survey the difference of spectra when Alq3 doped guest with different doping concentration in order that research the circumstance of energy transfer. We also success to synthesize the novel material of red dopant from green-dopant C545P,and name the red dopant “RC545P”. Then, we will measure the performance of the RC545P to compare with DCJTB that is often used to be the red dopant in OLED.
Finally, we prove the assumption that excimer formed by cyaniding group is result in the red shift of spectra. Moreover, the emission efficiency of RC545T (9.28) in solution is better than DCJTB (7.96), but the efficiency of Alq3 energy transfer to RC545T (17.88%) is worse than DCJTB (36.72%). In thin film, the emission efficiency of Alq3 doped RC545T (42.3) is closer than Alq3 doped DCJTB (48.9). the optimal concentration ratio of Alq3 doped RC545T is between 1% and 2%.
