國立臺灣師範大學化學系座落於公館校區理學院大樓。本系成立於民國五十一年,最初僅設大學部。之後於民國六十三年、七十八年陸續成立化學研究所碩士班和博士班。本系教育目標旨在培養化學專業人才與中等學校自然及化學專業師資,授課著重理論及應用性。本系所現有師資為專任教授25人,另外尚有與中央研究院合聘教授3位,在分析、有機、無機及物理化學四個學門的基礎上發展跨領域之教學研究合作計畫。此外,本系另有助教13位,職技員工1位,協助處理一般學生實驗及行政事務。學生方面,大學部現實際共322人,碩士班現實際就學研究生共174人,博士班現實際就學共55人。

本系一向秉持著教學與研究並重,近年來為配合許多研究計畫的需求,研究設備亦不斷的更新。本系所的研究計畫大部分來自國科會的經費補助。此外,本系提供研究生獎助學金,研究生可支領助教獎學金(TA)、研究獎學金(RA)和部分的個別教授所提供的博士班學生獎學金(fellowships)。成績優良的大學部學生也可以申請獎學金。

本校圖書館藏書豐富,除了本部圖書館外,分部理學院圖書館西文藏書現有13萬餘冊,西文期刊合訂本有911餘種期刊,將近約3萬冊。此外,西文現期期刊約450種,涵蓋化學、生化、生物科技、材料及其他科學類等領域。目前本系各研究室連接校園網路,將館藏查詢、圖書流通、期刊目錄轉載等功能,納入圖書館資訊系統中,並提供多種光碟資料庫之檢索及線上資料庫如Science Citation Index,Chemical Citation Index,Chemical Abstracts,Beilstein,MDL資料庫與STICNET全國科技資訊網路之查詢。

    Quantum-dot-embedded silica nanotubes as nanoprobes for simple and sensitive DNA detection

    We have developed a new technique using fluorescent silica nanotubes for simple and sensitive DNA detection. The quantum-dot-embedded silica nanotubes (QD-SNTs) were fabricated by a sol–gel reaction using anodic aluminum silica oxide (AAO) as a template. The fluorescent QD-SNTs of different colors were then immobilized with single-stranded DNA and used as nanoprobes for DNA detection. The optical and structural properties of QD-SNT nanoprobes were examined using photoluminescence spectroscopy, confocal microscopy and transmission electron microscopy (TEM). The QD-SNT nanoprobes were applied to detect dye-labeled target DNA in a solution phase. The obvious color change of the QD-SNT nanoprobes was observed visually under a simple microscope after the successful detection with target DNA. The quantitative analyses indicated that ~ 100 attomole of target DNA in one nanoprobe can generate a distinguishable and observable color change. The detection results also demonstrated that our assay exhibited high specificity, high selectivity and very low nonspecific adsorption. Our simple DNA assay based on QD-SNT nanoprobes is expected to be quite useful for the needs of fast DNA screening and detection applications.

    Electroluminescence from a Conjugated Polymer Grafted with CdSe/ZnS: High Brightness and Improved Efficiency
    (Wiley, 2006-09-15) K.-B. Chen; M.-H. Chen; S.-H. Yang; C.-H. Hsieh; C.-S. Hsu; Chia-Chun Chen; H.-J. Chien
    A new series of sulfide-substituted poly(1,4-phenylene vinylene) derivatives (S1PPV–S3PPV) with different composition ratios were successfully synthesized via the Gilch route. The CdSe/ZnS were grafted to the sulfur atoms by ligand exchange reaction. The grafted CdSe/ZnS contents were determined from TGA analysis to be from 4.6 to 37.8%. A new peak at 1151 cm−1 formed in FT-IR after ligand exchange, which is attributed to the force formation between sulfur and CdSe. The GPC results show that the molecular weights of final polymers became higher after ligand exchange. Thin films of obtained polymers emitted bright green and yellow light with the max emission peak located from 546 to 556 nm. Double-layer LEDs with an ITO/PEDOT/polymer/Ca/Al configuration were fabricated to evaluate the potential use of these polymers. The turn-on voltages of the devices were about 4–5 V. As the CdSe/ZnS content increased in grafted polymers, the device performance was significantly enhanced as compared to pristine polymers. In the case of S3PPV, the double-layer device showed a maximum luminance of 6073 cd/m2 with a current yield of 0.82 cd/A. The maximum luminance and current yield was enhanced to 13,390 cd/m2 and 2.25 cd/A by grafting CdSe/ZnS onto polymers.
