- •
An amphiphilic naphthopyran derivative (DSNP) was designed and prepared.
- •
DSNP can self-assemble into the LBL films with cationic quaternized poly(4-vinylpyridine).
- •
DSNP also assemble into light-responsive micelles with polyethylene glycol–triethylamine bromide.
- •
Naphthopyran displayed a markedly slower fading rate in LBL films.
- •
The photochromic reaction of naphthopyran induced disassembly and re-assembly of micelles.
