presented. Some push-pull chromophores (D-pi-A) containing polyphenylethynyl units and a phosphane oxide moiety were efficiently prepared from common intermediates. Straightforward syntheses gave novel one-armed, rod-shaped and three-armed, star-shaped fluorophores. The optical properties of the resulting star-shaped derivatives were evaluated, showed high fluorescence quantum yields, and their excitation
介绍了新型荧光团的设计。从常见的中间体可以有效地制备一些含有聚苯乙炔基单元和氧化膦部分的推挽发色团(D-pi-A)。直接合成得到新颖的单臂,杆状和三臂,星形荧光团。评价了所得星形衍生物的光学性质,显示出高的荧光量子产率,并且它们的激发引起非常有效的电荷重新分布。此外,由于其推挽特性,这些分子表现出显着的二阶NLO性质,具有良好的透明性,在1907 nm处可达67x10(-30)esu,在369 nm处具有吸收λ。在这项工作中,研究了供体基团和苯乙炔基臂数的影响。
