Uses
9-Bromophenanthrene is used as halogenated building block. Isotope labelled 9-Bromophenanthrene (B687200), a halogenated polycyclic aromatic hydrocarbon that has been seen to have a room temperature phosphorescence that can be induced by β-cyclodextrin (β-CD) in the presence of cyclohexane; however, trace Fe(III) causes a decrease of the RTP emission.
Preparation
An invention discloses a preparation method of 9-bromophenanthrene shown as in formula (II) that is shown in the description. The preparation method is characterized by including the steps of using phenanthrene shown in formula (I) that is shown in the description as a raw material, adding KBr bromination reagent, adding bromination reagent ZnAl-BrO3-LDHs into acetic acid and water mixed solvent, reacting at 20-70 DEG C for 2-5 hours to obtain reacted liquid that is post-treated to obtain the 9-bromophenanthrene shown as in the formula (II); the mas ratio of the phenanthrene shown as in the formula (I) to the KBr and ZnAlBrO3-LDHs is 1:0.9:0.6; the preparation method has the advantages that the preparation process is convenient, the reaction conditions are mild, low environmental pollution is caused, the requirements for equipment are low, bromine utilization rate is high, and the reaction time is short.
