Conjugated Polymers in Cages: Templating Poly(3-hexylthiophene) Nanocrystals by Inert Gel Matrices

Advanced materials


Polymer gels template the assembly of rrP3HT into micro/nanostructures in which the order and size of molecular domains can be controlled by the crosslinking degree of the templating gel.
The PMMA network regulates the assembly of P3HT and limits the formation of defects within NCs, if compared to solution processing. It is also observed that a lower crystallinity of P3HT aggregates in the more crosslinked matrix.
This approach could, in principle, be applied to other crystallizable polymers, besides P3HT, with a strong tendency to self-organize. The addition of this route to the current knowledge on microstructure control by molecular design and processing, could be of help to the design and realization of optimized all-organic systems for solar cells and other applications.
