In this contribution, we report experimental results to demonstrate the effects of chain collapse and segmental aggregation of conjugated polymer, poly[2-methoxy, 5-(2′-ethylhexyloxy)-1,4-phenylenevinylene](MEH-PPV), on its photophysics. We have found that the photoemission spectrum of isolated chai...
