Multicolor chemiluminescent acridinium derivatives were synthesized by attaching various common fluorophores to the N10‐acridinium position through a piperazine linker. Triggering of each acridinium derivative using alkaline hydrogen peroxide resulted in a chemiluminescence spectrum dominated by a strong emission (>95%) from the attached fluorophore. The highly quenched emission from the triggered...
A series of fluorescent pH probes based on the spiro-cyclic rhodamine core, aminomethylrhodamines (AMR), was synthesized and the effect of cycloalkane ring size on the acid/base properties of the AMR system was explored. The study involved a series of rhodamine 6G ( cAMR6G ) and rhodamine B ( cAMR ) pH probes with cycloalkane ring sizes from C-3 to C-6 on the spiro-cyclic...
