Effect of varying bases on preferential crystallization of <i>C</i>-methylresorcin[4]arene and calix[6]arene Harshita Kumari Arnab Dawn Charles L. Barnes 10.6084/m9.figshare.7082393.v1 https://tandf.figshare.com/articles/journal_contribution/Effect_of_varying_bases_on_preferential_crystallization_of_i_C_i_-methylresorcin_4_arene_and_calix_6_arene/7082393 <p>Preferential crystallization from a mixture of <i>C</i>-methylresorcin[4]arene (RsC1) and calix[6]arene (Calix6) in the presence of different bases has been investigated. In the presence of pyridine, a boat conformer of RsC1 crystallizes, whereas in the presence of triethylamine, Calix6 crystallizes in a symmetrically distorted conformation. The packing arrangements of the macrocycles show discrete solvent pockets for calixarenes and channels for resorcinarenes.</p> 2018-09-13 04:41:24 Calixarenes supramolecular chemistry macrocycles CrC Crystallization
