    1.Spirally Configured cis-Stilbene/Fluorene Hybrids as Ambiplor Templates for Organic Light Emitting Diode Applications

    Organic light emitting diodes (OLEDs) have been intensively investigated in the recent years for their potential applications in next generation full-color at panel displays and solid state lighting. However, the recombination efficiency of holes and electrons with unbalanced-charge carriers is one of the key factors for making bad device efficiencies. Therefore, we developed a new class of cis-stilbene/fluorene spiro hybrid systems with hole-transporting, electron-transporting and ambipolar organic fluorescent materials for optoelectronic applications. These types of materials exhibited a stable amorphous glassy state (Tg:120-167 oC) and stable decomposition temperatures (Td: >400 oC). One of the fluorescent materials, N-STIF-P(O)Ph2, had ambipolar charge transport feature with balanced hole and electron mobilities (μh: 6.510-6 cm2/Vs

    13: M = Co). When the slightly more steric hindered amidinate ligand (Li[HC(NDep)2]) was employed to react with anhydrous FeCl2 and CoCl2, the lantern type complexes, Fe2[(μ-κ2-HC(NDep)2]3 (11) and Co2[(μ-κ2-HC(NDep)2]3 (15) are also the major products. [0/1]
    2013年研究調查發現,台灣五位民眾中就有一人有失眠的困擾,而人類一生的活動中,大約花三分之一的時間於睡眠上,有很多文獻研究指出睡眠的重要性,以及睡眠品質如何影響生活品質。床墊良好與否是影響睡眠品質的重要變因,因此提供一個舒適的床組是很重要的課題。本實驗目的為設計出符合人體生理以及心理需求的床墊,進而提升國人睡眠品質。
    本研究分為兩實驗。實驗一招募32位受試者。針對四種不同表面加工設計,以及不同材質疊加的床墊組合進行人因評估實驗,透過收集生理訊號及主觀問卷進行分析。生理訊號包含全身壓力分佈、全身溫度分佈以及微氣候溫濕度。在實驗一研究結果的基礎之下,進行第二階段的實驗以補實驗一結果之不足。實驗二招募12位受測者,針對六張新款材質,與不同表面紋路設計的床墊組合進行實驗,收集的數據如同實驗一,包含生理與心理兩部分。
    在全身壓力分佈方面,實驗一以沒有進行表面設計加工的床墊壓力值較低,實驗二結果可知壓力大小與床墊厚度無關,而全身壓力最大的地方皆位於臀部。全身溫度方面,實驗一中有加工的床墊溫度值較低,可見加工有達到通風散熱的目的,而實驗二溫度較低的三款床墊皆使用到相同成分的材料,僅表面處理方式不同,因此可推測實驗二影響溫度的主因是材料本身的特性,以及再次證明表面加工的加乘效果。微氣候溫度於實驗一結果與全身溫度分佈相同,亦為有加工的床墊溫度值較低。微氣候濕度的部分表現較佳的床墊與溫度結果相反,溫度低的床墊相對的濕度也較高。主觀數據的部分,實驗一的部分床墊主觀感受無太大差異,而實驗二為經表面切割與疊加的床墊在各項目普遍為排序第一。
    本研究之結果將提供業界不同床墊的生理數據,以及消費者的主觀感受,未來廠商開發新型床墊將能由此方向進行設計。

    4,5-b_]–dithiophene (m-FP-BTDT), were grown on the Au (111) and modified Au (111) substrate as the organic semiconductor thin films, respectively. The growth mechanisms, the molecular orientations and the electronic structure of the thin films were analyzed via XPS, NEXAFS and UPS. In addition, the above results were combined with the XRD and AFM data to reach a thorough understanding of the performances of various OFETs. The thermal desorption data show that the chemisorbed P-BTDT layer remains thermally stable up to 750 K on Au(111). However, P-BTDT desorption on Au-BT substrate is found to derive exclusively from physisorption state, and chemisorption desorption is entirely suppressed. Based on the change of XPS intensity with the amount of P-BTDT deposited, it is concluded that the growth of P-BTDT film on Au(111) follows the Stranski-Krastanov mechansim, i.e., a completion of one monolayer (2D growth) followed by a 3D crystallite growth. In comparison, for the growth of P-BTDT on Au(111)-benzenethiolate, a pseudo 2D-like growth is observed. From the results of UPS, the change of work function and valence band spectrum with the film-thickness is in accord with this growth behavior. The results obtained by XPS are also in agreement with UPS observations. The molecules of the multilayer grown on Au(111)-BT have their aromatic rings inclined toward the surface by an average 66°, as determined by NEXAFS data. For the thick film grown on Au(111), out-of-plane x-ray diffraction reveals the presence of several crystallite alignment schemes. In contrast, the XRD data of the thicker layer grown on Au(111)-BT show (002) diffraction peaks only, indicating that the crystal orientation of the thin film is (002) preferred. Therefore, we can change the crystal structure and control the growth behavior of the thin film through different modification of substrates, leading to an improved performance of the OFETs. The results show that P-BTDT thin film that is grown on BT-Au can yield a better OFET mobility up to 3.0 × 10-2 cm2/Vs with thickness of 120 nm.
    In order to shift energy level of LUMO toward lower value, we also prepared m-FP-BTDT organic semiconducting thin films and investigated their properties. XPS intensity analysis shows that on Au(111), m-FP-BTDT film grows according to Stranski–Krastanov (SK) mode. It is interesting to note an abrupt increase of Au 4f signal at around one ML of m-FP-BTDT, which is explained by the production of excess Au adatoms, accompanied by the lifting of the herringbone reconstruction of Au(111). In comparison, the initial growth of m-FP-BTDT on Au-BT proceeds via a pseudo layer-by-layer growth mechanism. NEXAFS data show that m-FP-BTDT molecules on Au-BT adopt a more erected configuration, the angle between the molecule and substrate is 62.5°, resulting in a better cofacial π-stacking. The XRD pattern reveals that the crystal growth orientation of m-FP-BTD thin film is along c axis. Work function for the thick m-FP-BTDT film on Au-BT is determined with UPS as 4.62 eV and the hole injection barrier as 0.94 eV. According to above results the thin film of m-FP-BTDT grown on Au(111)-BT is expected to produce better carrier transport phenomenon.
