HCH2CH2 (CHJ3)],) with R'CA (neohexyl isocyanurate) and R” CA (3, 3, 3-triphenylpropyl isocyanurate) in CHCI,, respectively, yields structurally well-defined supramolecular aggregates~ U~ M,(R'CA)~ and flexM3 (R” CA),. These structures were characterized using'H NMR, I3C NMR, and UV spectroscopy, gel permeation chromatography, and vapor pressure osmometry. flexM, is a conformationally flexible analog of hubM,.
