N2 - The nature of interchain excitations in conjugated polymers was discussed. The spatially-varying solvatochromism of annealed poly(2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene) (MEH-PPV) films were studied by near-field scanning optical microscopy (NSOM). The solvatochromic spectral shifts of the interfacial luminescence were measured as a function of solvent polarity. The results were analyzed with an interfacial dielectric continuum model to determine the dipole moment of emissive excited states.
