Nanoparticles via H-aggregation of amphiphilic BODIPY dyes

We have synthesized wedge-shaped BODIPY dyes with hydrophilic chains and studied their aggregational behavior in THF-containing water by UV vis and photoluminescence spectroscopies, transmission electron microscopy, and dynamic light scattering. One of these dyes showed an aggregate derived from H-dimers and forms a high density nanoparticle in THF-containing water solution. (C) 2010 Elsevier Ltd. All rights reserved.
