10-tetrabromopyrene-4,5-dione as the key intermediate. The effects of the position and number of the ethynyl groups on the physicochemical properties of the corresponding pyrenes were clarified by comparison with 4,5,9,10-tetraethynylpyrene and 2,7-diethynylpyrene derivatives. The prepared hexaethynylpyrenes that bear benzene moieties self-assemble via π–π stacking in solution and/or the condensed phase.
以2,7,9,10-四溴py-4,5-二酮为主要中间体合成了一系列的2,4,5,7,9,10-己炔基吡啶。通过与4,5,9,10-四乙炔基py和2,7-二乙炔基derivatives衍生物的比较,明确了乙炔基的位置和数量对相应pyr的理化性质的影响。制备的带有苯部分的六乙炔基吡啶通过在溶液和/或缩合相中的π-π堆积而自组装。
