dc.description.abstract本研究利用Knoevenagel reaction 將1,4-及1,3-phenylene diacetonitrile 與N-(2-octyl)-3,6-diformylcarbazole反應合成出不同π-有效共軛鏈長度(π-effective conjugation lengths) 的Poly[ (p or m)(carbazolylene phenylene cyanovinylene) ]【p-PCPC及m-PCPC】配位的共軛高分子。利用引入不同配位(para及meta)來達到控制高分子鏈段的共軛長度。所製得p-PCPC及m-PCPC高分子具有不錯的熱穩定性(在氮氣下5﹪熱損失重量分別為453℃及475℃),可發現meta 配位相較para配位構形高分子較具有好的熱穩定性。從Uv-visible 吸收光譜可發現在393nm至413nm左右顯示出一個相當強的π-π*吸收峰,另外p-PCPC及m-PCPC PL光譜中最大發光波長分別從514nm至578nm,這種紅移現象和其配位有關。從CV (cyclic voltammetry)的電化學實驗分析可知其highest occupied molecular orbitals (HOMO)為5.30 eV及5.60 eV,而lowest unoccupied molecular orbitals (LUMO)為3.21 eV及3.30 eV 。另一方面所製備的發光二極體發光元件〔ITO/polymer/Al〕起始電壓約為3-4V,並且p-PCPC及m-PCPC分別發出黃-紅光(601nm)及綠光(534nm)。zh_TW
dc.description.abstractPoly[ [p,or(m)-carbazolylene-phenylene-cyanovinylene) ]【p-PCPC, m-PCPC】polymers with varyingπ-effective conjugation lengths was synthesized using Knoevenagel reaction between 1,4-(1,3)-phenylene diacetonitrile and N-(2-octanyl)-3,6-diformylcarbazole. The conjugation lengths of polymers were controlled by kink (para and meta)linkages. The resulting polymers(p-PCPC)and m-PCPC have good thermally stable on heating(the weight loss was less than 5﹪on heating to about 435℃ and 475℃ under nitrogen atmosphere), meat conformations are more stable than para conformations. The Uv-visible absorbance of present polymers showed strong absorption bands around 393-413 nm byπ-π* transition. In addition, the maximum photoluminescence (PL)of p-PCPC and m-PCPC were changed from 514 nm to 578 nm . The PL of p-PCPC was red-shifted about 60 nm compared to that m-PCPC depending on link structure. Electrochemical analyses by cyclic voltagemetry indicate that highest occupied molecular orbitals (HOMO) of p-PCPC and m-PCPC to be(5.30 eV , 5.60 eV, and lowest unoccupied molecular orbitals (LUMO)energy levels(3.21 eV, 3.30 eV. Otherwise , a single layer light emitting diode device was fabricate, which has simple ITO / Polymer / Al configuration. The threshold voltage of polymers was in range of 3-4 V. These polymers of p-PCPC and m-PCPC exhibit red-yellow and green light-emitting diodes in EL emissive band at 601nm and 534 nm .en_US
