Synthesis of probes with broad pH range fluorescence
摘要:
Reaction of a rhodamine 2'-ester with an excess of alkyldiamines provides amino-functionalized rhodamine spirolactams, which when subsequently conjugated with carboxyfluorescein, provides probes which are fluorescent at acidic, neutral, and basic pH ranges.
