The ability to improve exciton diffusion lengths is a key issue in optimizing many opto-electronic devices based on conjugated polymers. On the basis of quantum-chem. calculations, we investigate a strategy consisting of extending the radiative lifetime of energy carriers through incorporation along the polymer backbone of repeating units with forbidden optical transition. The results obtained for poly(p-phenylenebutadiyne), PPE, and poly(p-triphenylenebutadiyne), PTPE, show that the larger number of hops performed by the electronic excitations during their lifetime in PTPE is compensated by the smaller hopping length (associated with the reduced conjugation length), so that similar on-chain diffusion lengths are predicted in both polymers. The results came from multiple reactions, including the reaction of 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Related Products of 74029-40-6)
1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers.Oxygen is more electronegative than carbon, thus the alpha hydrogens of ethers are more acidic than those of simple hydrocarbons. Related Products of 74029-40-6 They are far less acidic than alpha hydrogens of carbonyl groups (such as in ketones or aldehydes), however.
