Experimental and theoretical study of temperature dependent exciton delocalization and relaxation in anthracene thin films
(Georgia Institute of Technology, 2008-02)
The spectroscopy of solid anthracene is examined both experimentally and theoretically. To avoid experimental complications such as self-absorption and polariton effects, ultrathin polycrystalline films deposited on ...
Breakdown of the mirror image symmetry in the optical absorption/emission spectra of oligo(para-phenylene)s
(Georgia Institute of Technology, 2005-01)
The absorption and emission spectra of most luminescent, π-conjugated, organic molecules are the mirror image of each other. In some cases, however, this symmetry is severely broken. In the present work, the asymmetry ...
Structure-property relationships for three-photon absorption in stilbene-based dipolar and quadrupolar chromophores
(Georgia Institute of Technology, 2006-07)
Based on essential-state models for three-photon absorption (3PA), we have investigated the structure-property relationships for stilbene-based dipolar and quadrupolar chromophores. The emphasis lies on the evolution of ...
Three-photon absorption in anthracene-porphyrin-anthracene triads: A quantum-chemical study
(Georgia Institute of Technology, 2004-12)
We have applied correlated quantum-chemical methods to investigate the three-photon absorption (3PA) response of a porphyrin triad derivative, where the central macrocycle is linked in mesopositions to two anthracene units ...
