The relationship of structure to optical spectral properties was determined for five types of fluors in a search for an optimum-wavelength shifter to be used as part of the detection systems for high-energy particles from accelerators. In a search for photostable fluors to serve as waveshifters in plastic fibers it was found that the wavelengths of interest, absorption max 410 +/- 10 nm and fluorescence
确定了五种类型的荧光的结构与光谱性质之间的关系,以寻找一种最佳波长位移器,以用作促进剂中高能粒子检测系统的一部分。在寻找光稳定的荧光粉作为塑料纤维中的移波器时,发现感兴趣的波长,最大吸收波长为410 +/- 10 nm和最大荧光发射量为480 +/- 20 nm,以及其他特性,例如高溶解度仅通过使用氨基作为有机色素,可以使由芳环和乙烯基组成的荧光团获得荧光,并且荧光衰减时间短。由于伯,单烷基和二烷基氨基基团不能充分光稳定,因此对许多带有二芳基氨基基团的荧光团进行了研究。荧光的合成利用了布赫瓦尔德胺化,埃蒙斯-霍纳反应和其他常见反应的改进形式。氟的类型如下:2-苯并恶唑基-7-(4-二芳基氨基)芴7,2-(4-氰基苯基)-5-(4-氨基苯基)恶唑14和20,1,3,5-己三烯24a -d和26a-c,1,4-二苯乙烯基苯31d-g和32a-e以及2,7-二苯乙烯基芴40a,de。不对称的氟7
