Luminescent diazaborolyl-functionalized polystyrene
Kuhtz H, Cheng F, Schwedler S, et al. Luminescent diazaborolyl-functionalized polystyrene. ACS Macro Letters. 2012;1(5):555-559.We present two different procedures for the synthesis of poly[4-(1′,3′-diethyl-1′,3′,2′-benzodiazaborolyl)styrene] (3a) and poly[4-(1′,3′-diphenyl-1′,3′,2′-benzodiazaborolyl)styrene] (3b). The new polymers were fully characterized by GPC, multinuclear NMR, and elemental analysis. The thermal properties and stability were studied by DSC and TGA, and the optical characteristics were examined by absorption and time-resolved fluorescence spectroscopy. Remarkably high quantum yields of up to 77% were measured. In comparison to molecular species we found significantly shorter lifetimes, likely as a result of incorporation of the chromophores into the polymer structure
