我們藉由合環反應合成了含不同氮數的芳香雜環，並搭配上含未共軛之輔助
配位基合成了一系列的鉑二價錯合物，並且利用輔助配位基磷原子上的苯環來提
供立體障礙，使得這一系列化合物都沒有Pt-Pt作用力的存在。這一系列的化合
物除了dfPPyPtP^O在室溫溶液下可放出極弱的磷光外，其他的在溶液下均不放
光。其放光波段隨著含氮雜環上的氮數增加有藍位移(blue shift)的趨勢；從465
nm到474 nm，但是因為其半高寬太寬(50~75 nm)，而使得放出之光色為藍綠光。
以dfppyPtP^O以及TriazoPyPtP^O這兩個化合物當作磷光摻雜物分別做了元件A
以及元件B，以下是所做出來的元件結果：
元件Ａ：NPB(30 nm)/mCP:dfPPyPtPO(10%,30 nm)/BCP(10 nm)/Alq(30 nm)/LiF/Al
，元件外部量子效率(ηext)為2.13 %，電流效率(ηc)為5.84 cd/A，最大亮度(Lmax)
為6596 cd/m2，CIE座標為(0.17,0.45)。
元件B: NPB(30 nm)/mCP:TriazoPyPtP^O(10%,30 nm)/BCP(10 nm)/Alq(30
nm)/LiF/Al，元件外部量子效率(ηext)為2.17 %，電流效率(ηc)為6.10 cd/A，
最大亮度(Lmax)為4951 cd/m2，CIE座標為(0.21,0.49)。

We used cyclolization to synthesize heteroaromatics that contain different numbers of
N to combine with non-conjugated ancillary ligand to synthesize a series of Pt(II)
complex. The phenyl group on the P atom of ancillary ligand created steric hindrance
which inhibits the Pt-Pt interaction in this series of compound. This series of
compound did not emit phosphoresence in solvents besides compound dfppyPtP^O;
yet, its emittance was rather weak. As the number of N in the heteroaromatics
increased the emitting λmax blue shifted from 465 nm to 474 nm. However, the width
of the full-width-half-maximum (FWHM) was too wide which resulted in the
emittance of blue-green light.
We take dfPPyPtP^O and TriazoPyPtP^O as dophants to construct devices A and B,
and the followings are the results.
Device A: NPB(30 nm)/mCP:dfPPyPtPO(10%,30 nm)/BCP(10 nm)/Alq(30
nm)/LiF/Al; this device can achieve an external quantum efficiency(ηext) of 2.13%,
current efficiency(ηc) of 5.84 cd/A, maximum brightness(Lmax) of 6596 cd/m2, and
CIE coordinates of (0.17,0.45). Device B: NPB(30 nm)/mCP:TriazoPyPtP^O(10%,30
nm)/BCP(10 nm)/Alq(30 nm)/LiF/Al; this device can achieve an external quantum
efficiency(ηext) of 2.17%, current efficiency(ηc) of 6.10 cd/A, maximum
brightness(Lmax) of 4951 cd/m2, and CIE coordinates of(0.21,0.49).
