Fluorescence behavior of a unique two-photon fluorescent probe in aggregate and solution states and highly sensitive detection of RNA in water solution and living systems.


It is found that 2,7-substituted carbazole derivative possesses distinct luminescence features in both aggregate and solution states. In view of this, probe realizes highly sensitive detection of RNA in pure water systems by an aggregation-disaggregation method for the first time.
