Computational studies on the electronic properties of several poly(p-phenylene vinylene) derivatives
Abstract
HyperChem® 7 software was used to compute for the electronic properties of PPV and its derivatives (PPPV, PO-PPV, MEH-PPV, DEO-PPV, and DMAPPV). In this study, the PPPV derivative was calculated to have the lowest ionization potential, lowest band gap (2.845851 eV), and the highest value for the bandwidth (7.605665 eV). This derivative also possessed the highest mean polarizability value. MEH-PPV was determined to possess the most stable structure since it has the least total energy (−274,824.6875 kcal/mol). The highest total dipole moment was also computed for this polymer. The partial charge distribution was graphed, revealing the greatest alternation of charges for PO-PPV, MEHPPV, and DEO-PPV.
