(1)、分子内含有发射荧光的基团,如羰基、氮氮双键、碳氮双键等。
(2)、分子内含有助色基团。助色基团使光谱红移并增大荧光效率,如伯胺基、仲胺基、羟基、醚键、酰胺基等。
(3)、分子内含有刚性平面结构的共轭π键。分子内共轭体系愈大平面性愈强其荧光强度愈高。一些能提高共轭度的因素能提高荧光效率,并使荧光波长向长波方向移动。 就是荧光染料的附着物,主要作用有帮助荧光染料展色、提高荧光染料与下游树酯的相溶性、保护荧光染料的性能。通常载体树脂是强极性树脂,分子中含有胺基、羟基、醚键、酰胺基等强极性基团,一方面有助色作用,增大荧光效率;另一方面与荧光染料有很好的相溶性,有助于染料的均匀分散。
荧光颜料常用的载体树脂有胺基树脂、苯代三聚氰胺一甲醛树脂、聚丙烯酸酯树脂、聚酰胺树酯、聚酯树脂、聚氨酯树脂等。 (1)、热塑性荧光颜料:线型

健那绿染液是一种活体染液,实验对象必须是活细胞,健那绿可以使活细胞中的线粒体呈现蓝绿色,而细胞质接近无色。
荧光燃料使用的问题有两个:
一个就是迁移性,使用时要严格控制用量,以避免产生迁移现象;
二是荧光染料使用有一个极限值,如果超量使用,导致荧光线被吸收,使吸收和发光成叠所致。
