Abstract

Blends of poly(3-dodecyl thiophene) (PDDT) with poly(methyl methacrylate), poly(butyl methacrylate) (PBMA), and poly(methyl methacrylate-co-butyl methacrylate) (PMMA/PBMA) were studied by polarization optical microscopy, atomic-force microscopy, and absorption spectroscopy and were modeled using molecular dynamics (MD) simulations. The observed thermochromic transitions are shown to be host-matrix dependent, with PDDT/PBMA absorption spectra differing substantially from pristine PDDT. The dispersion of PDDT within PBMA matrix is observed to be greater than in the other host polymers. MD calculations of both individual PDDT molecules and molecular aggregates suggest that the distribution of dihedral angles present in the PDDT backbone is the narrowest for aggregates of PDDT embedded within a polymer matrix.
