The planarity and high fluorescence quantum yield of pyrene make it an important building block in organic optoelectronic material. But 2-pyrene based conjugated materials are less developed due to the intrinsic low reactivity of 2-position. A series of (1-hydroxy)-2-pyrenylphosphine derivatives were synthesized from pyrenyl phosphates via phospho-Fries rearrangement under mild conditions. The pyrenyl phosphate precursors could be easily obtained from the reaction of 1-pyrenol with H-phosphonates or phosphine chlorides. Several pyrenyl phosphates were converted into new pyrene fused 1,3-oxaphospholes from the further reactions with N-arylimide chlorides. This research provides not only a convenient method for the funcationalization of pyrene at 2-position but also new organophosphorus based π-conjugated molecules. The absorption and emission properties of these new pyrene fused molecules were studied.
