Two new classes of dendrimers bearing 8 and 32 fluorene donor groups have been synthesized. The first and second generations of these porphyrin-PAMAM-fluorene dendrimers were characterized by 1H-NMR, 13C-NMR, FTIR, UV-vis spectroscopy, elemental analyses and MALDI-TOF mass spectrometry. The UV-vis spectra showed that the individual properties of donor and acceptor moieties were preserved, indicating that the new dendrimers could be used as photosynthetic antennae. Furthermore, for fluorescent spectroscopy, these dendrimers showed good energy transfer.

已经合成了两类分别带有8个和32个芴供体基团的新型树枝状聚合物。这些卟啉 - PAMAM - 芴树枝状聚合物的第一代和第二代通过1H - NMR、13C - NMR、FTIR、紫外 - 可见光谱、元素分析和基质辅助激光解吸电离飞行时间质谱进行了表征。紫外 - 可见光谱表明供体和受体部分的各自特性得以保留，这表明新的树枝状聚合物可用作光合天线。此外，对于荧光光谱，这些树枝状聚合物显示出良好的能量转移。
