PMID: 29488769
Langmuir. 2019 Apr 09;35(14):5075-5080. doi: 10.1021/acs.langmuir.7b04385. Epub 2019 Mar 27.

Long-range anisotropic structural materials exhibit notable optical and mechanical properties, and an efficient method for synthesizing such materials involving self-assembly of well-defined monodispersed organic molecules is described here. Hetero-double-helices are formed in toluene using a pseudoenantiomeric mixture of an...
