A Sensitive Indication of the Rigid Microenvironment of the Bile Salt Aggregate Room Temperature Phosphorescence Probe

In this paper, we report the investigation of the interaction between room temperature phosphorescence(RTP) probe, α bromonaphthalene( α BrN), and a series of cholate surfactants using RTP spectroscopy. It was found that intense RTP of α bromonaphthalene can only be induced in aqueous deoxycholate sodium(NaDC) solution. This observation showed that the interior structure of NaDC aggregate was more rigid and efficient in shielding the excited state of α BrN from oxygen quenching. The experiments suggested that the more chiral separation capability of NaDC aggregate of could be due to its more rigid interior structure.
