Pyrazoline-based fluorophores and plastic scintillators incorporating the fluorophores are described. The fluorophores include 1,3,5-triaryl substituted pyrazolines. A fluorophore of a plastic scintillator can be a 1-phenyl-4,5-1H-dihydroyrazole having the structure:
in which R
1
and R
2
are independently selected from a heteroaryl group including one or more of an oxygen, selenium or sulfur atom in the ring; an aryl halide group; or a phenyl alkyl including a C1 to C18 saturated or unsaturated alkyl that optionally includes a reactive functionality.
本文描述了基于吡唑啉的荧光染料和包含该荧光染料的塑料闪烁体。荧光染料包括1,3,5-三芳基取代的吡唑啉。塑料闪烁体的荧光染料可以是具有以下结构的1-苯基-4,5-1H-二氢吡唑酮:其中R1和R2分别选自杂环基团,包括环中的一个或多个氧、硒或硫原子;芳基卤化物基团;或苯基烷基,包括一个C1到C18的饱和或不饱和烷基,该烷基可以选择性地包含一个反应性官能团。
