The notoriously non‐luminescent uncycled azophenine (Q) was harnessed with Bodipy and zinc(II)porphyrin antennas to probe its fluorescence properties, its ability to act as a singlet excited state energy acceptor and to mediate the transfer. Two near‐IR emissions are depicted from time‐resolved fluorescence spectroscopy, which are most likely due to the presence of tautomers of very similar calculated

卟啉天线一起使用,以探测其荧光特性,其作为单线激发态能量受体并介导转移的能力。时间分辨荧光光谱法描述了两个近红外发射,这很可能是由于存在计算出的总能量非常相似的互变异构体(350 cm -1; DFT; B3LYP)。1 Bodipy *→ Q的能量传递速率k ET(S 1)约为10 10 –10 11 s -1当考虑到最低的
