Item type:Item, Synthesis and Isomeric Effects of Ladder-Type Alkylated Terbenzodithiophene Derivatives(2016-03-18) ;Chen, Yung-Lung ;Hsu, Jhih-Yang ;Lin, Fang-Yu ;Lai, Yu-YingChou, Hsiao-ChiehA new class of heptacyclic ladder-type terbenzodithiophene (TBDT) structures merging three fused benzodithophenes was developed. Two TBDT conjugated isomers, named as syn-TBDT and anti-TBDT, where the two thienyl rings in the outmost BDT units are in the syn- and anti-fashion, are designed. Two decyl groups are introduced to their 6,13 and 7,14-positions to form four isomeric 6,13-syn-TBDT, 7,14-syn-TBDT, 6,13-anti-TBDT, and 7,14-anti-TBDT structures which are constructed by the DBU-induced 6-benzannulation involving propargyl-allenyl isomerization of the dieneyne moieties in the corresponding precursors followed by 6 pi-electro-cyclization/aromatization, while isomeric TD-syn-TBDT and TD-anti-TBDT with four decyl groups substituted at 6,7,13,14-positions are synthesized via palladium-catalyzed dialkylacetylene insertion/C-H arylation of the corresponding iodobiaryl precursors. The intrinsic properties can be modulated by molecular manipulation of the main-chain and side-chain isomeric structures. anti-TBDT derivatives exhibit higher melting points, larger bandgaps, stronger intermolecular interactions, and higher mobility than the corresponding syn-TBDT analogues. These molecules can be further utilized as building blocks to make various TBDT-based materials for optoelectronic applications.Item type:Item, Photo-induced Doping in GaN Epilayers with Graphene Quantum Dots(2016-03-18) ;Lin, T. N. ;Inciong, M. R. ;Santiago, S. R. M. S. ;Yeh, T. W.Yang, W. Y.We demonstrate a new doping scheme where photo-induced carriers from graphene quantum dots (GQDs) can be injected into GaN and greatly enhance photoluminescence (PL) in GaN epilayers. An 8.3-fold enhancement of PL in GaN is observed after the doping. On the basis of time-resolved PL studies, the PL enhancement is attributed to the carrier transfer from GQDs to GaN. Such a carrier transfer process is caused by the work function difference between GQDs and GaN, which is verified by Kelvin probe measurements. We have also observed that photocurrent in GaN can be enhanced by 23-fold due to photo-induced doping with GQDs. The improved optical and transport properties from photoinduced doping are promising for applications in GaN-based optoelectronic devices.Item type:Item, 漫遊輕小說(2016-03-20) ;陳緯僑 ;Department of Communication and Technology傳播與科技學系輕小說是許多年輕人愛不釋手的讀物之一,除了讀者,其影響力也間接擴及青少年的生活與次文化當中。Item type:Item, 職棒二十六 精彩回顧(2016-03-20) ;李宗諺 ;Department of Communication and Technology傳播與科技學系中華職棒迄今邁入第二十七個年頭,每一年都有它值得回味的地方,讓我們回顧去年、放眼今年。Item type:Item, 勇敢相伴 與過往和解(2016-03-20) ;孔婉寧 ;Department of Communication and Technology傳播與科技學系當生命遇上前所未有的低谷時,向下沉淪或往上提升是唯一的路,該如何選擇?Item type:Item, 金馬導演報你知(2016-03-20) ;許凱智 ;Department of Communication and Technology傳播與科技學系細數臺灣電影最高殊榮的金馬導演們的那些小事,看看他們都有哪些特質。Item type:Item, 旅社整建 小西風華再現(2016-03-20) ;唐宜嘉 ;Department of Communication and Technology傳播與科技學系位於彰化小西街內的紅葉大旅社,經過整修與改建後再現五〇年代的風華。Item type:Item, 1949青旅 打造台灣文創夢(2016-03-20) ;鄭宇茹 ;Department of Communication and Technology傳播與科技學系一群年輕人以青年旅館出發創業,期望能做到文化保存的目標。Item type:Item, 竊取原創 淪為設計抄襲(2016-03-20) ;修瑞韓 ;Department of Communication and Technology傳播與科技學系設計抄襲時常發生,但是大眾對於抄襲的定義與程度模糊。Item type:Item, 活生生 生命的再賦予(2016-03-20) ;黃美恩 ;Department of Communication and Technology傳播與科技學系兩位北藝大的學生,在這個別有特殊意義的城市,舉辦一場活生生的雙人展。Item type:Item, 轉型正義 正視撕裂的歷史(2016-03-20) ;胡浣莊 ;Department of Communication and Technology傳播與科技學系轉型正義是當今政府及民眾熱議的話題,無論是黨產還是白色恐怖,皆有待平反。Item type:Item, 邁向高齡 台灣政策亮警戒(2016-03-20) ;謝萱穎 ;Department of Communication and Technology傳播與科技學系隨著醫療的進步發展,全球已經逐步邁向高齡、超高齡社會,未來甚至恐將出現人口負成長的現象。Item type:Item, 自由人公寓 藝術交流平台(2016-03-20) ;林謙耘 ;Department of Communication and Technology傳播與科技學系自由人藝術公寓為一個結合展覽、咖啡廳、酒吧、住宿的複合式展場。Item type:Item, 搖滾傳奇 披頭四(2016-03-20) ;趙廣絜 ;Department of Communication and Technology傳播與科技學系以互動式動畫介紹搖滾樂團披頭四(The Beatles)。Item type:Item, 外籍勞工在臺灣(2016-03-20) ;翁世樺 ;Department of Communication and Technology傳播與科技學系隨著外籍勞工在臺人數的增加,其相關議題也受到重視。Item type:Item, 新聞賣錢以後(2016-03-20) ;許人文 ;Department of Communication and Technology傳播與科技學系探討收視率主導下,新聞媒體守門人功能不再,新聞品質低落等媒體亂象頻傳,該如何才能打破收視率的迷思?Item type:Item, 我的熊爸爸(2016-03-20) ;梅瑞庭 ;Department of Communication and Technology傳播與科技學系細田守在二〇一五年推出的第四部動畫電影【怪物的孩子】,描述人類的小孩在妖怪界長大成人的故事。Item type:Item, 農業新創 科技突破傳統(2016-03-20) ;王聖安 ;Department of Communication and Technology傳播與科技學系當傳統農業碰上創新科技,超乎想像的智慧化農業時代已經來臨。Item type:Item, 大誌雜誌 幫助自助者(2016-03-20) ;黃吏玄 ;Department of Communication and Technology傳播與科技學系簡單的整理,讓大誌雜誌如何幫助街友一目瞭然。Item type:Item, 被忽視的英雄 志氣與破風(2016-03-20) ;林儒均 ;Department of Communication and Technology傳播與科技學系透過【志氣】與【破風】,討論臺灣體壇資源問題。他們是被忽視的英雄,除了練習,還必須擔心著自己的未來。
