Abstract
Electromodulation spectroscopy of polydiacetylenes poly-4,6-decadiyne-1,10-diol-bis(n-butoxycarbonyl-methylurethane) (PDA-3BCMU) and poly-1-(N-carbazolyl)penta-1,3-diyn-5-ol (PDA-CPDO) reveals a Stark redshift in the former and spectral broadening in the latter. The results support the previous assignments of the lowest optical transition in PDA-3BCMU to the excitonic and in PDA-CPDO to the interband transitions.Keywords
