paper we report the synthesis and characterization of four novel pentacoordinated diorganotin complexes, obtained through a methodology that involves a multicomponent reaction of 4-([9H-fluorene-2-yl]ethynyl)-2-hydroxybenzaldehyde, 2-amino-5-nitrophenol and diphenyl or dibutyl-tin oxides. Diorganotin complexes 8–11 were obtained in high yields (70–80%) and were fully characterized by solution NMR (1H
在本文中,我们报告了四种新型五配位二有机锡复合物的合成和表征,这些复合物是通过涉及4-([[9H-芴-2-基]乙炔基)-2-羟基苯甲醛,2-氨基-5的多组分反应的方法获得的-硝基苯酚和二苯基或二丁基锡的氧化物。Diorganotin复合物8-11以高收率(70-80%)获得,并通过溶液NMR(1 H,13 C和119完全表征)Sn),高分辨率质谱(ESI-TOF)和ATR-FTIR。通过UV / Vis光谱和双光子激发荧光(TPEF)研究了光学性质。单光子吸收(OPA)光谱显示两个位于400和500 nm左右的谱带,此外,在双光子吸收(TPA)光谱中有一个位于750 nm左右的主谱带,其特征是TPA横截面的最大值(σ TPA)在450–500 GM范围内,次级带位于1000 nm,最大σTPA70 GM的值;2,2-二丁基-6-氮杂-1,3-二氧杂-11-([[9,9-二己基-9H-芴-2
