| Abstract | Reaction of the tris(melamine) derivatives hubMr (CnHr- 1,3,5-(CONHC6H4- 3-N(9ryrCnHo-4-C (CHr)r)COC6- H,-2-NHC.,Nr(NHr )(NHCHTCHTC(CHr) r)-5-Brl.) and flexM. (CoHr-1,3,5 (CO:(CHr),OCOC6H I-2-NHCTN)(NH2)( N- HCHTCHT(CU,lrltJ with R,CA (neohexyl isocyanuiate) and R"CA (3,3,3-triphenylpropyt isocy-anurate) in CHClr, respectively, yields ,truiturali.r- well-defined supramoleculir aggregates hubMq(R'CA)3 and flexM3(R"CA)3. These structures were characterized using ,H NMR, rlC NMR, and UV spectroscopy, gel permeation chromatography, and vapor pressure osmometry. flexM, is a confor-mationally flexible analog of hubM.,. The greater degree of preorganization that is built into the molecular structure of hubM3 compaied to flexM., ttiuk.r hubMr(R'Cn)i a more stable aggregate than flexMr(R"CA)r. These self- assembling structuies arethe first step in a program to design, synthesize. and develop methods to characterize supramolecular |
