The design, synthesis, and characterization of 12-phenylbenzo[f][1,7]phenanthroline, Bzp, is reported. Its use as a fluorine-free ligand for sky blue phosphorescence is demonstrated in a cyclometalated platinum complex, BzpPtDpm. BzpPtDpm phosphoresces at the same wavelength as its analogous 4,6-difluorophenylpyridine complex at both room temperature (466 nm) and 77 K (458 nm). Finally, production
报道了12-苯基苯并[ f ] [1,7]菲咯啉Bzp的设计,合成和表征。在环金属化铂络合物BzpPtDpm中证明了其用作天蓝色磷光的无氟配体的用途。BzpPtDpm在与其在室温下(466 nm)和77 K(458 nm)下的类似的4,6-二氟苯基吡啶复合物相同的波长处发出磷光。最后,BzpPtDpm构象受限的衍生物的产生,其量子产率大大提高(46%),证明了合成路线的多功能性。
