芘具有良好的刚性平面和高的荧光量子产率, 是有机光电材料研究中重要的结构单元, 由于其电子结构特点, 芘的2位官能团化非常困难. 利用易得的1-芘醇和H-亚磷酸酯或有机磷氯化合物合成了一系列1-芘基磷酸酯化合物, 经磷杂Fries重排反应在温和条件下实现了芘2位的磷酰化, 并得到相应的2-磷酰基芘衍生物. 该类化合物还为新型含磷共轭化合物芘并1,3-氧杂磷杂环戊二烯的研究奠定了基础. 本研究不但为芘类化合物的官能团化提供了一个新方法, 而且为新型含磷共轭化合物的设计与合成开辟了新路线, 并对合成的新型芘类化合物的紫外吸收和荧光发射等性质进行了初步测定.

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.
