一系列具有有機薄膜電晶體性質之有機光電材料成功合成。 於 p-type 部分以3,3′-bis(tetradecyloxy)-2,2′-bithiophene (OBT) 為核心,末端外掛dithienothiophene (DTT),合成出DDTT-OBT-14。 n-type OTFT部分分別以支鏈二十併二?吩與併二?唑為核心合成出?行分子DST-TTQ-b20和DST-TTzQ-b20。 以上新型OTFT分子之光學與電化學性質(HOMO 與LUMO)分別由UV與DPV進行測量。熱性質則由TGA與DSC進行測量。此外,上述材料元件效能尚在測試中。 ;A series of new organic optoelectronic materials were synthesized and characterized for Organic Field-Effect Transistors (OFETs). 3,3′-bis(tetradecyloxy)-2,2′-bithiophene (OBT)-based new organic semiconductor DDTT-OBT-14 (1) end-capped with dithienothiophene (DTT) units was synthesized and characterized for p-type OFETs. 2-octyldecyl substituted thienothiophene (TT) and thiazolothiazole (TTz)-based quinoidal compounds, DST-TTQ-b20 (2) and DST-TTzQ-b20 (3), were prepared and characterized for n-type OFETs. The optical and electrochemical properties (HOMO and LUMO) of these new materials were characterized by UV-vis and DPV. Thermal properties were investigated by DSC and TGA. Further, device characterization studies for these newly synthesized compounds are under optimization.
