New bis-aldehyde functionalized initiators, viz, 4,4′-(4,4′-(5- hydroxypentane-2,2-diyl)bis(4,1-phenylene))bis(oxy)dibenzaldehyde (1) and 4,4′-bis(4-(4-(formylphenoxy) phenyl) pentyl 2-bromopropanoate (2) were synthesized starting from commercially available 4,4′-bis(4-hydroxyphenyl) pentanoic acid. These initiators were utilized, respectively, for ring opening polymerization of -caprolactone and atom transfer radical polymerization of styrene. Well-defined polycaprolactone macromonomers (MnGPC: 2600-19400, PDI: 1.37-1.47) and polystyrene macromonomers (MnGPC: 2800-28200, PDI: 1.11-1.16) with bis-aldehyde functionality were synthesized. The kinetic study of styrene polymerization showed controlled polymerization behaviour. The presence of aldehyde functionality in macromonomers was confirmed by 1H NMR spectroscopy. The reactivity of aldehyde functionality was demonstrated by carrying out aldehyde-aminooxy click reaction of polycaprolactone macromonomer with O-(2-azidoethyl) hydroxylamine which proceeded in a quantitative manner without backbone degradation.

, p. 9229 - 9235 (2007/10/03)
The synthesis of new organothiol-functionalized dendrons of generation 1-4 is described. Several modifications to the original method for preparation of dendrons are detailed that were found to improve the yield and aid in scale-up. A particularly advanta

A novel double-stage convergent growth approach for the preparation of dendritic macromolecules is described. In the first stage, convergent growth with 4,4-bis(4′-hydroxyphenyl)pentanol as the building block is used to create symmetrical dendritic struct
