Close packing between alkyl side chains of a confugated polymer and tails in an phospholipid in nanoparticles due to comparable chain length induces displacement along cojugated backbones by steric hindrance, resulting in enhanced interchain electron delocalization by the displacement together with ∏-∏ stacking. The absorption band with bathochromic shift in nanoparticles of the congugated polymer is a combination of absorption spectraby both intra-and intermolecular electron delocalization.
