Theoretical study on mesogenic core structure of nematic liquid crystalline compounds

Article Abstract:

The structures and intermolecular interaction energies of 10 dimers, included in the mesogenic core structures of typical liquid crystalline (LC) compounds, are studied. The results suggest an explicit linear relationship between the interaction energies and viscosities of these 10 dimers.

Chiral molecule motors ignited by femtosecond pump-dump laser pulses

Article Abstract:

The results of the theoretical study on a chiral molecular motor ignited by a femtosecond pump-dump laser excitation are presented. Motor dynamics, like dephasing or rephasing, was analyzed in terms of rotational wave packet propagation on the ground-state potential surface.

Time-dependent density functional theory investigation of electric field effects on absorption spectra of meso-meso-linked zinc porphyrin arrays: Role of charge-transfer states

Article Abstract:

The transition energies of a zinc porphyrin monomer and its meso-meso-linked arrays are calculated by using time-dependent density functional theory. The processes in which transition energies of the dimer array are shifted by an applied electric field are examined.
