Assembling small functional molecules using dendrimers [1] and dendronized
(Mn = 9,300, PDI = 1.02). Using GPC analysis to estimate the molecular weight of the dendronizedpolymer was not appropriate, because both the Mn and Mw values of the obtained dendronized polystyrene 8b were only twice that of the starting polystyrene 7b (Table 1). SEC–MALLS analysis indicated that 6
