近年來，有機電激發光二極體（OLED）被期望可以應用在全彩的平面顯示器上，但是到目前為止，藍光發光材料仍舊未達到所希望的高亮度效率及型態穩定性。而為了改善這些條件，除了由元件結構優化之外，從最根本的分子設計，則是本次論文研究的重點。
　　Anthracene衍生物是目前較常被使用在OLED的螢光主體材料。而近年來也有許多研究專注在改善材料結構的立體障礙及抑制excimer的產生，而以雙芴環為核心結構的分子最常被提出。因此，本次的研究論文，即以雙芴環為核心結構，以anthracene衍生物為側鏈基團的分子結構。
此研究以Suzuki coupling反應合成新型的藍光材料，分別為2,2'-bis(9,10-di(naphthalen-2-yl)anthracen-2-yl)-9,9'-spiro-bi[fluorene] (BNASBF) 及 2,2',7,7'-tetrakis(9,10-di(naphthalen-2-yl)anthracen-2-yl)-9,9'-spirobi[fluorene] (TNASBF)。
我們研究了新材料的熱穩定性、成膜型態及光學特性，並將其製作成元件探討其元件特性。
量測結果顯示，TNASBF此系列材料在波長440 nm的地方為主要放光波長，在溶液態時也有不錯的螢光效率，可達80%，但是隨著濃度增加卻會有濃度淬息的現象產生，且元件光譜有極大的變化，因此在製作成元件時混在其他材料內反而有比較好的效率，目前效率可達到最大亮度達1003 cd/m2。

Organic light-emitting devices (OLEDs) haves attracted much attention for using in full-color flat-panel display. But so far, blue emitting materials are still need to develop with sufficient luminous efficiency and morphology stability.
Anthracene derivatives are known materials commonly used as an host in doped system for OLEDs. In recent years, more and more research paper about method to obtain structural bulk and suppresses excimer formation are that introduce spiro-
bifluorene group.
Therefore, in this study we used Suzuki cross-coupling reaction to synthesize novel spirobifluorene based deep-blue emitting molecules, namely 2,2'-bis(9,10-di(naphthalen-2-yl)anthracen-2-yl)-9,9'-spiro-bi[fluorene] (BNASBF) and 2,2',7,7'-tetrakis(9,10-di(naphthalen-2-yl)anthracen-2-yl)-9,9'-spirobi[fluorene] (TNASBF), which contains an spirobifluorene core and two or four anthracene derivative end-capped groups.
We examined the thermal, morphological and photophysical properties of the materials.
TNASBF has main emitting wavelength at 440 nm, and it has great quantum yield in solution type (80%). However, there are concentration quench and the CIE coordinate are different. Until now, the device efficiency is 1003 cd/ m2.
