Two linear 1,4‐distyrylbenzenes and five star‐shaped 1,3,5‐tristyrylbenzene derivatives (L2a and L2b , Y0–Y3 and YNBu ) were synthesized and spectroscopically characterized. The photophysical properties, optical response to acid and metal ions were investigated. Upon backbone extension of linear distyrylbenzenes or the introduction of dibutylanilines, the electronic spectra are redshifted. Incorporation
合成了两种直链1,4-二苯乙烯基苯和五种星形1,3,5-三苯乙烯基苯衍生物( L 2a和L 2b 、 Y 0 –Y 3和Y NBu )并进行了光谱表征。研究了光物理性质、对酸和金属离子的光学响应。当直链二苯乙烯苯的主链延伸或引入二丁基苯胺时,电子光谱发生红移。缺电子吡啶基单元的加入不会显着影响光学性能。吡啶环数量和取代模式的变化可调节对酸和金属离子的荧光响应。新型芳烃区分Al 3+ 、Mn 2+ 、Fe 3+ 、Fe 2+ 、Cd 2+ 、Ag +和Hg 2+ 。
