Controlling molecular ordering in solution-state conjugated polymers.
Rationally encoding molecular interactions that can control the assembly structure and functional expression in a solution of conjugated polymers hold great potential for enabling optimal organic optoelectronic and sensory materials. In this work, we show that thermally-controlled and surfactant-guided assembly of water-soluble conjugated polymers in aqueous solution is a simple and effective s...

متن کاملQuantum Molecular Dynamics Simulations of Conjugated Polymers
The softness of conjugated polymers leads to strong coupling between polymer’s electrons and lattice vibrations. Therefore, it is necessary to perform quantum molecular dynamics computer simulations in order to study their electronic and optical properties at molecular level. We have used self-consistent molecular dynamics calculations with inter-atomic forces evaluated from quantum mechanical ...
متن کاملGroundstate dispersion interaction between pi-conjugated polymers.
The line-dipole approximation is used to investigate the scaling of the groundstate dispersion interaction, EW, between parallel conjugated polymers of length L and transverse separation D. Both a second-order perturbation theory calculation using the Mott-Wannier exciton model of excited states and a semiclassical analysis of distributed dipoles indicate that at L approximately D there is a cr...
متن کاملMolecular crystal approach for π-conjugated polymers: from PPP Hamiltonian to Holstein model for polaron states
Starting from the π-electrons Pariser-Parr-Pople (PPP) Hamiltonian which includes both strong electron-phonon and electron-electron interactions, we propose a strongly correlated wave function for the ground state of conjugated polymers. This wavefunction describes nearest-neighbour intermonomer charge fluctuations in the background of paired electrons localized on monomers. With this picture, ...
