Examples
- 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
实验结果显示，最有效的双光子吸收材料是由电子给体和电子受体对称或反对称的与一个中心结合而成的系统。 - 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
它能与电子给体n ， n -二甲基苯胺( dma )和电子受体1 ， 4 -二氰基苯( dcb )相互作用生成激基复合物，并能与dma形成三元激基复合物。 - 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
本论文以稀土配合物oel为重点和基础，以eu ( dbm ) _ 3bath和gd ( dbm ) _ 3bath为典型材料，研究了激基复合物的形成和稀土配合物器件中混合层能够消除激基复合物，认为激基复合物是电子受体材料配体能级的单重态与电子给体材料的基态相互作用而产生的。 - 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
我们分别以苯、二苯乙烯、噻吩为中心，氨基、二苯氨基和二乙氨基为电子给体，硝基为电子受体组合形成的分子为研究对象，在从头计算的水平上用密度泛函理论计算了这些分子在低激发态下的单、双光子吸收强度，重点研究了分子的长度、中心和给体的供电子能力对分子单、双光子吸收的影响。研究结果表明，分子长度与单光子吸收强度之间有密切关系，而在双光子吸收中这种关系较弱；中心在双光子吸收中具有重要的作用；在中心和受体一定的情况下，增加给体的供电子能力，可提高双光子吸收强度。 - The fluorescence spectra of the conjugationed polymer containing of n - ( a - naphthyl ) carbazole show that the emission sprctra in aromatic solvents are more red - shifted than that in aliphatic solvents although these solvents have the same polarity . the fluorescence chatacteristics were different from th e n - ( a - naphthyl ) carbazole ' s . the fluorescence of the conjugationed polymer can be quenched by electron donors and cm and cannot be quenched by electron acceptors
对含有n - ( -荼基)咔唑基团的共轭高聚物，它在芳香族溶剂中的荧光发射比非芳香族溶剂中明显红移，也不具有n - ( -萘基)咔唑单元所具有的分子内电荷转移特性，它的荧光只能被电子给体和c _ ( 60 )猝灭而不能被一般的电子受体猝灭。
