摘要：本文是一项研究计划的导论,旨在说明:决定中国当代艺术发展的关键因素,是西方的影响以及中国对这一影响的回应。同时,本文也阐述了研究中国当代艺术的几个问题,尤其是内在研究与外在研究相贯通的问题。在此前提下,本文提出"全球化与本土化的焦虑"一说,并用此说来阐释影响与回应的关系,进而提出作者的"阐释世界的符号结构观"。换言之,本文作者通过研究中国当代艺术而提出独到的学术观点,又反过来用这一观点来表述作者对当代艺术的研究。

摘要：有明一代山水画发展的主流,经历了一个由外向内的转变,前期画家寻道于自然,后期画家转而寻道于内心。本文通过图像研究而旨在阐述:明代山水画主流的转向,实为对前代山水画发展主流的重复,而重复的终点则是明末山水画中点景小人的缺席,这标志了主流的终结。这一探讨从德里达关于意指延异的概念出发,借鉴解构主义的双重阅读,来分析明代山水画中寻道者的意象及其在符号系统中作为意指中心的功能。本文结论是,当文人山水画发展到明末,寻道者意象的缺失,使中国山水画的意指系统被解构,艺术史的主流遂于明末消散。

摘要：Thermally activated delayed fluorescence(TADF) sensitized fluorescent organic light-emitting diodes(TSF-OLEDs) have shown great potential for the realization of high efficiency with low efficiency rolloff and good color purity. However, the superior examples of TSF-OLEDs are still limited up to ***, a trade-off strategy is presented for designing efficient TADF materials and achieving highperformance TSF-OLEDs via the construction of a new type of triazolotriazine(TAZTRZ) acceptor. The enhanced electron-withdrawing ability of TAZTRZ acceptor, fused by triazine(TRZ) and triazole(TAZ)together, enables TADF luminogens with small singlet-triplet energy gap(ΔE_(ST)) values. Meanwhile, the increased planarity from the TRZ-phenyl linkage(6:6 system) to the TAZ-phenyl linkage(5:6 system)can compensate the decrease of oscillator strength(f) while lowing ΔE_(ST), thus achieving a trade-off between small ΔE_(ST) and high f. As a result, the related TSF-OLED achieved an extremely low turn-on voltage of 2.1 V, an outstanding maximum external quantum efficiency(EQEmax) of 23.7% with small efficiency roll-off(EQE1000 of 23.2%;EQE5000 of 20.6%) and an impressively high maximum power efficiency of 82.1 lm W^(-1), which represents the state-of-the-art performance for yellow TSF-OLEDs.

摘要：Organic light-emitting diodes(OLEDs)have drawn tremendous attention due to their widespread applications in flat-panel displays and solid-state lightings over the years[1-4].The charge injection is crucial for the performance of OLEDs featuring sandwiched p-i-n structures[5-9].For OLEDs,an indium tin oxide(ITO)electrode with a work function of 4.7 eV,and most holetransporting materials(HTMs)with the highest occupied molecular orbitals(HOMOs)close to-5.5 eV.

摘要：热活化敏化荧光(TSF)被称作有机发光二极管(OLED)“第四代发光技术”,是以热活化延迟荧光材料作为敏化剂,高效发光的荧光材料作为掺杂染料,通过二者之间高效的Förster能量传递实现100%激子利用,突破了三线态高效上转换与单线态高效辐射跃迁之间的矛盾.本文围绕TSF-OLED器件的发光效率、寿命及光色等核心指标,针对激子的调控和利用这一关键科学问题,重点介绍了我们课题组近年来在TSF技术的机理研究、高效稳定敏化剂及窄光谱材料的设计开发以及高性能器件的构筑等方面的研究工作.最后讨论了TSF技术所存在的挑战和未来发展前景.

摘要：A new strategy of thermally activated delayed fluorescence(TADF)material-sensitized circularly polarized luminescence(CPL)has been proposed for improving the efficiencies of fluorescent circularly polarized organic lightemitting diodes(OLEDs)(CP-OLEDs).Consequently,a pair of helicene enantiomers,(P)-HAI and(M)-HAI,were *** helicene enantiomers with the rigid helicalπ-skeleton had highly thermal and enantiomeric stabilities,and they also showed excellent photophysical properties,especially,intense mirror-image CPL activities with large luminescence dissymmetry factor(|g_(lum)|)values of about 6×10^(-3).Notably,the CP-OLEDs with the helicene enantiomers as emitters and a TADF molecule as sensitizer not only displayed better performance of lower turn-on voltage(V_(T))of 2.6 V,four-fold maxmium-external quantum efficiency(EQE_(max))of 5.3%,and lower efficiencies roll-off of 1.9%at 1000 cd m^(-2),than those of the devices without TADF sensitizer,but also exhibited intense circularly polarized electroluminescence(CPEL)with the electroluminescence dissymmetry factor(g_(EL))values of-2.3×10^(-3)and+3.0×10^(-3).Meanwhile,this study also represents the first thermally activated sensitized fluorescent CP-OLEDs with markedly enhanced efficiencies and intense CPEL.

摘要：本文简要讨论将西方现代艺术理论引入视觉文化研究和教学的实践问题。本文采用潘诺夫斯基的图像学理论,从中国文化对日本文化的影响讨论教学实践。西方有学者认为,潘氏图像学只适合于阐释西方文艺复兴式的艺术作品,另有学者则持不同意见。本文即持后一意见。文中所涉及的跨文化研究个案,既有西方理论与东方实践的空间跨度研究,也有中国南宋、日本江户、西方现代的时间跨度研究。

摘要：在西方当代学术界的视觉文化研究中,人体不再是单纯的审美对象,而被视为具有社会性的观念文本。本文从艺术家与城市空间之互动关系的社会视角,考察西方当代摄影对女性身体的再现,考察摄影对公共空间及其隐秘之处的探索,考察其对女性性从业者之身份问题的探索,由此在西方当代批评理论的语境中,揭示当代视觉文化和观念艺术中身体图像和身份问题的社会意义。这一系列考察借鉴了英国心理学家温尼科特和法国心理学家拉康之精神分析的主要概念,也借用了"文本身体"等当代性别研究中的批评概念。
