In aerated aqueous solution, intense room-temperature phosphorescence (RTP) of 1-bromonaphthalene (1-BrN) is observed with an host-guest inclusion complex composed of Triton X-100, 1-BrN, and beta-cyclodextrin (beta-CD). Triton X-100 is incorporated into the hydrophobic cavity of beta-CD as the second guest molecule, and a 1:1:1 ternary complex is formed. This complex, with a polar head group, can be well distributed in aqueous solution, and stable RTP is obtained. Ethanol further enhances the RTP of the ternary complex, whereas 1-propanol and 1-butanol greatly attenuate RTP. Spectral analyses indicate that 1-BrN in the beta-CD cavity is replaced by 1-propanol and 1-butanol.
