electron donor-acceptor
解釋
電子給受體-
We have calculated one - and two - photon absorption cross sections of the lowest excited states of a series of molecules combined with benzene, stilben, thiophene as center attached with amine, diphenylamine, diethylamine as electron - donor and nitryl as electron - acceptor ; the effects of molecular length, n center and electron - donor on two - photon absorption cross sections have been studied and all calculations have been carried out using the density functional theory at an ab initio level. it is found that the molecular length and the one - photon absorption intensity are quite strongly c orrelated factors, and that a corresponding correlation for the two - photon absorption is decreasing. it is also found that a most crucial role for the two - photon absorption is played by the n center
我們分別以苯、二苯乙烯、噻吩為中心，氨基、二苯氨基和二乙氨基為電子給體，硝基為電子受體組合形成的分子為研究對象，在從頭計算的水平上用密度泛函理論計算了這些分子在低激發態下的單、雙光子吸收強度，重點研究了分子的長度、中心和給體的供電子能力對分子單、雙光子吸收的影響。研究結果表明，分子長度與單光子吸收強度之間有密切關系，而在雙光子吸收中這種關系較弱；中心在雙光子吸收中具有重要的作用；在中心和受體一定的情況下，增加給體的供電子能力，可提高雙光子吸收強度。 -
The fluorescence of copolymer ( dmbn - vcz ) can be quenched by both electron donor ( n, n - dimethylaniline ( dma ) ). electron acceptor ( 1, 4 - dicyanobenzene ( 1, 4 - dcb ) ) and c60. the dimolecular exciplexes between copolymer ( dmbn - vcz ) and stronger electron donor or electron acceptor are formed, respectively
它能與電子給體n ， n -二甲基苯胺（ dma ）和電子受體1 ， 4 -二氰基苯（ dcb ）相互作用生成激基復合物，並能與dma形成三元激基復合物。 -
The color of devices is disturbed badly and the luminescent efficiency of devices is degradated because of exciplex ' s emission. the mechanism is investigated in this paper on the formation of exciplex and on the mixing - layer device structure eliminating the exciplex based on rare - earth complex, specially on eu ( dbm ) 3bath and gd ( dbm ) 3bath. it is thought that the exciplex results from the interaction between the singlet excited state of the ligand of electron acceptor material and the ground state of electron donor material
本論文以稀土配合物oel為重點和基礎，以eu （ dbm ） _ 3bath和gd （ dbm ） _ 3bath為典型材料，研究了激基復合物的形成和稀土配合物器件中混合層能夠消除激基復合物，認為激基復合物是電子受體材料配體能級的單重態與電子給體材料的基態相互作用而產生的。 -
The enhanced photoconductive effect from small amount of tnf facilitates the preparations of new organic photoconductive devices under the drive of low fields. in the fourth chapter, inclpc nanoparticles embedded in poly ( n - vinylcarbzaole ) ( pvk ) were prepared successfully by dissolving inclpc in aprotic organic solvent / lewis acid with great concentration for the formation of electron donor - acceptor complexes, i. e., the method of complexation - mediated solubilization. the fabricated inclpc nanoparticles were characterized by means of uv / vis absorption, x - ray diffraction pattern, and tem
論文的最後一章中，我們合成了具有較好的電子傳輸性能的化合物』一二苯基四竣酸花酚亞胺（ ddp ） ；研究了其溶解性、熱穩定性、晶體結構、紅外光譜、紫外吸收光譜和蒸鍍薄膜的屬性，並用量子化學計算方法模擬其單分子的空間構型；載流子遷移率測試的結果約為ix10 「 、 m 』 v 」 』 ? s 「 』 。 -
The results of experiments show that the most efficient tpa materials seem to be the ones with various electron - donor ( d ) and electron - acceptor ( a ) moieties attached symmetrically or asymmetrically to a center
實驗結果顯示，最有效的雙光子吸收材料是由電子給體和電子受體對稱或反對稱的與一個中心結合而成的系統。
