(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
(2)、热固性荧光颜料: 体型
(3)、可溶解色精荧光颜料
(4)、水乳型荧光颜料 (1)、胺基树酯
(2)、聚酰胺树酯
(3)、聚酯树酯
(4)、丙烯酸乳液 (1)、塑胶类
低温型
中温型
高温型
(2)、涂料类
水性涂料
油性涂料
粉末涂料 (1)、含甲醛
(2)、不含甲醛
希望同路人多多交流啊!
想请问一下,DAPI这个染料到底有没有膜通透性,我通过百度搜索查询关于DAPI染料的,基本上是说它能透过细胞膜对活细胞和死细胞均能染上蓝色;但是也有人说DAPI只可以透过死细胞膜,不能对活细胞进行染色,用以区分活死细胞,到底哪个是对的啊,蒙了!!!!!!
