Supramolecular Chirality Using Both Cooperative and Isodesmic Self-Assembly: hierarchical growth through competition

Autor: A. J. H. Spiering, Tom T. Hoeben, Jef A. J. M. Vekemans, Anja R. A. Palmans, Martijn A. J. Gillissen, E. W. Meijer

Publikováno v: Israel Journal of Chemistry, 51(10), 1118-1127. Wiley-VCH Verlag

A novel set of chiral self-assembling discotic molecules has been prepared based on two previously studied self-assembling C3-discotic systems, namely alkyl substituted benzene-1,3,5-tricarboxamides (alkyl-BTAs) and 3,3'-bis(acylamino)-2,2'-bipyridin
