摘　　要：合成了８个以若丹明６Ｇ、若丹明１０１、若丹明Ｂ或若丹明ＤＲ－２１为母体，以１，８－萘酰亚胺衍生物为天线基元，以双亚甲基作为桥链连接两者的多发色团（双、或三发色团）激光染料，并对它们进行吸收光谱和荧光光谱的测试。结果表明，发生了从天线基元指向若丹明母体的分子内能量传递现象，并且多发色团激光染料相对于对应的若丹明染料的荧光量子产率有不同程度的提高。Multichromophoric(bi-or tri-chromophoric)laser dyes,consisting of 1,8naphthalimide derivatives as antennas and rhodamine 6G,rhodamine 101,rhodamine B or rhodamine DR-21 as a lasing moiety linked via an ethylene,have been synthesized and investigated by means of measurements of absorption spectra and fluorescence spectra.The fluorescence of the antennas in these multichromophoric dyes was partly quenched.The energy transfer from antenna to rhodaminc is observed,the fluorescencc quantum yield of the multichromophoric dyes can be increased by this energy transfer to rhodamine.
