23. No heterodimers were observed, however, by addition of 6-n-nonyl-2-n-octylureidopyrimidin-4(1H)-one to 1a.
24. ass* determined by integration of one signal of the calixarene unit in the monomer (δ=6.6, t) and dimer (δ=6.5, t) was on same order of magnitude.
25. NH signals were assigned by this experiment.
