摘要:
A fluorescent probe which is represented by the following formula (wherein R 1 and R 2 represent hydrogen atom, or a substituent for trapping proton, a metal ion, or an active oxygen species; R 3 represents a monovalent substituent other than hydrogen atom, carboxy group, or sulfo group; R 4 and R 5 represent hydrogen atom, a halogen atom, or an alkyl group; R 6 to R 9 represent an alkyl group; R 10 and R 11 represent hydrogen atom, a halogen atom, or an alkyl group; M - represents a counter ion; and the combination of R 1 , R 2 , and R 3 (1) imparts a substantially high electron density to the benzene ring to which they bond so that the compound can be substantially non-fluorescent before trapping proton, a metal ion, or an active oxygen species, and (2) substantially reduces electron density of the benzene ring to which they bond so that the compound after trapping proton, a metal ion, or an active oxygen species can be highly fluorescent after the trapping.
摘要(中):
由下式(其中R 1和R 2表示氢原子或用于捕获质子的取代基,金属离子或活性氧类)表示的荧光探针; R 3表示除氢原子以外的一价取代基,羧基 基团或磺基; R 4和R 5表示氢原子,卤素原子或烷基; R 6至R 9表示烷基; R 10和R 11表示氢原子,卤素原子或烷基 基团; M - 表示抗衡离子;并且R 1,R 2和R 3(1)的组合对它们所键合的苯环赋予了基本上高的电子密度,使得化合物可以基本上不发生荧光 捕获质子,金属离子或活性氧,以及(2)大大降低了它们键合的苯环的电子密度,使得捕获质子,金属离子或活性氧的化合物可以是高度荧光的 陷后。
