The traditional deoxygenation techniques for cyclodextrin induced room temperature phosphorescence (CD-RTP) include N₂(g) purging and Na₂SO₃ chemical deoxygenation.In this paper,with 1-bromocyclohexane (1-BrCH) as an external heavy atom perturber,7,8-benzoquinoline (7,8-BQ) was used as a model compound,hydrogen and carbon dioxide are used for deoxygenation in CD-RTP and compared with two traditional deoxygenation techniques.The results show that the new deoxygenation techniques have obvious advantages such as simpler facilities,faster speed of deoxygenation and wider acidity range etc.
