Chlorophyll pigments often assemble in a poor solvent to form less-ordered amorphous aggregates, despite the in vitro self-aggregation observed with chemically modified chlorophyll derivatives biomimicking a chlorosome. Chlorophyll dimer linked with a terephthalamide formed well-defined fiber shaped aggregates in hexane. The nanofiber was constructed by columnar self-aggregation via hydrogen bonding between terephthalamide moieties, which is different from chlorosomal aggregates that typically is formed by a coordination as well as hydrogen bonding.

叶绿素二聚体氢键构成的超分子纳米纤维

叶绿素颜料通常会在不良溶剂中聚集，形成秩序较差的无定形聚集体，尽管使用化学修饰的叶绿素衍生物仿生了脂质体观察到了体外自聚集现象。与对苯二甲酰胺连接的叶绿素二聚体在己烷中形成轮廓分明的纤维状聚集体。纳米纤维是通过对苯二甲酰胺基团之间的氢键通过柱状自聚集而构建的，这不同于通常由配位以及氢键形成的氯体聚集体。
