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 subsidiary company, yongan fuhuaxian articles supply factory, can produce 191 serial unsaturated polyester resin which is a clear and heavy - bodied liquid. it is made by the method of the solvation of linear unsaturated polyester resin, which is condensated and polymerized after the esterification of biatomic acid and diatomic alcohol, into phenylethylene solvent, which is a crosslinking active monomer
