New dissymetrical non conjugated bichromophores linked by an oxygenated chain: (9-anthrylmethyloxymethyl)arenes[arenes:benzene(Ia),2-naphthalene(Ib),9-phenanthrene (Ic) and 1-pyrene (Id) and (9-phenanthrylmethyloxymethyl)-1-pyrene (II)] have been prepared. Ic–d and II exhibit intramolecular exciplex fluorescence in methylcyclohexane at room temperature. Intramolecular photoadducts were not found but
通过氧链连接的新的不对称非共轭双发色团:(9-蒽甲氧基甲基)芳烃[芳烃:苯(I a),2-萘(I b),9-菲(I c)和1-py(I d),以及(9-菲基甲氧基甲基)-1-py(II)已经制备。I c–d和II在室温下在甲基环己烷中显示分子内激基复合物荧光。没有发现分子内的光加合物,但我和他产生了头对头和头对尾蒽类二聚体的混合物。
