We prepared dialkyl-heterocoerdianthrones (dialkyl-HCDs) and dialkyl-benzodixanthene (dialkyl-BDXs), which are well soluble in organic solvents, depending on the respective length of alkyl group. And the dialkyl-HCD and -BDXs aggregation behavior is switched by photo-oxidation, due to structural change in the molecule. Some compounds of those were found to be potential photo-reactive solubilizers of nano-carbon materials, due to this switching. In particular dipropyl-HCD acts as the solubilizer of single-walled carbon nanotubes (SWNTs) in chloroform. The SWNTs are precipitated from the dispersion liquid through irradiation with visible light. Such photo-induced precipitation was also observed in SWNT/dipropyl-HCD complex film.

我们制备了二烷基杂并二蒽酮（二烷基-HCD）和二烷基-苯并二蒽（二烷基-BDX），它们在有机溶剂中溶解性良好，具体取决于各自烷基的长度。由于分子结构的变化，二烷基-HCD 和-BDXs 的聚集行为通过光氧化而改变。由于这种转换，其中的一些化合物被发现是纳米碳材料的潜在光反应增溶剂。特别是，二丙基-HCD 充当氯仿中单壁碳纳米管 (SWNT) 的增溶剂。通过可见光照射，SWNT从分散液中析出。在SWNT/二丙基-HCD复合膜中也观察到这种光诱导沉淀。
