A hyperbranched porous polymer P based on adamantane and pyrene was synthesized through the Sonogashira coupling reaction. The three-dimensional rigid molecular skeleton of adamantane makes polymer P porous. Compound M, which acts as the block moiety between two adamantane groups in polymer P, was also synthesized for the control experiment. Compared with M, the characteristics of P changed remarkably with it exhibiting different emission behaviors and performances for the detection of DNT. In saturated DNT vapor, the quenching efficiency (ηEP) of film P (82%) was remarkably superior compared with that of film M (22%). In addition, a series of films with different thicknesses and different amounts of polymer P were prepared. Results showed that the quenching efficiencies did not change with an increase in the film thickness. [ABSTRACT FROM AUTHOR]
