Shielding effects in spacious macromolecules: a case study with dendronized polymers.
Dendronized polymers exhibit defined structures with bulky side chains (dendrons) on a linear polymer backbone. Upon reaction with radicals, chromophores close to the backbone were bleached. The reaction rate and yield decreased with increasing dendron size, demonstrating that the inside of dendronized polymers can be "shielded" by bulky dendrons from access by reactive species.
متن کاملMolecular structure of single DNA complexes with positively charged dendronized polymers.
Positively charged dendronized polymers with protonated amine groups at the periphery and different dendron generations are cylindrically shaped nanoobjects whose radii and linear charge densities can be varied systematically. These polyelectrolytes have been complexed with DNA and subsequently adsorbed on precoated mica substrates. The analysis of scanning force microscopy data indicates that ...

متن کاملRodlike macromolecules through spatial overlapping of thiophene dendrons.
Two novel dendritic macromonomers 7 and 8 functionalized with electroactive conjugated thiophene oligomers were synthesized by stepwise cross-coupling reactions and the introduction of a vinyl group at the focal point. Both macromonomers were polymerized into dendronized polymers 9 and 10 by using a radical polymerization method. The photophysical and redox behaviors of dendronized polymers 9 a...
متن کاملSolvent induced phenomena in a dendronized linear polymer
The properties of a dendronized linear polymer (DP) in dilute solutions depending on solvent quality and temperature are described. The polymer has a contour length of Lc = 1,060 nm. The sample of the fourth generation (PG4) was analyzed in the thermodynamically good solvents dioxane, chloroform, and methanol. The wormlike macromolecule has a persistence length lp = 7 nm in dioxane and a cross-...
