title: Shielding effects in spacious macromolecules: a case study with dendronized polymers.
abstract: 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.
