abstract
Various bi-functional pyrazine-based chromophores were used as cross-linkers to probe directly the efficiencies of their incorporation into the shell of block copolymer micelles. In addition, the block copolymer micelles were made to carry pre-installed reactive functionalities along the central block of an amphiphilic triblock copolymer. Unique photo-physical characteristics were observed, depending upon the type of pyrazine cross-linker, the conditions used for cross-linking and the stoichiometries applied. 2009 The Royal Society of Chemistry.
