The topology of frontier molecular orbitals (FMOs) induces highly sensitive charge transfer coupling with variation in the intermolecular arrangement. A consistent optoelectronic property correlated to a specific aggregate architecture independent of the nature of the monomer is a rare phenomenon. Our theoretical investigation on stacked dimeric sy...
Article
Null aggregates are elusive, emergent class of molecular assembly categorized as spectroscopically uncoupled molecules. Orthogonally stacked chromophoric arrays are considered as a highlighted architecture for null aggregates. Herein, we unveil the null exciton character in a series of crystalline Greek cross (+) assembly of 6,13-bisaryl substitute...
Article
Aromaticity, though widely used to delineate diverse photochemical phenomena, remains to be examined in excimers, a fundamental and extensively studied entity in the excited states. Herein, the first theoretical evidence for excited state through-space aromatic character in triplet state (T1) excimers of benzene, naphthalene and anthracene is repor...
Article
A series of π-conjugated tetrabenzoacenes (TBA), including nitrogen (un)doped derivatives are computationally evaluated to comprehend the correlation between intrinsic structural arrangements and charge transport characteristics. The central charge transport parameters such as reorganization energy and electronic coupling are individually tuned thr...
Article
Exzitonenkopplung kann minimiert sein bei rechtwinkliger Stapelung, wie 1965 bereits von Kasha et al. vorausgesagt. In ihrer Zuschrift (DOI: 10.1002/ange.201810209) bringen M. Hariharan und Mitarbeiter nun den experimentellen Nachweis einer ausbleibenden Exzitonenkopplung, und folglich unbeeinträchtigter angeregter Zustände und selektiven Lochtrans...
Article
Greek cross stacking (α=90°) mediated negligible exciton coupling has been theoretically known since 1965 (Kasha et al.). In their communication (DOI: 10.1002/anie.201810209) M. Hariharan and co‐workers report the first experimental evidence of null exciton coupling mediated unperturbed photoexcited state properties and selective hole transport in...
Article
Exciton interactions in molecular aggregates play a crucial role in tailoring the optical behavior of π‐conjugated materials. Though vital for optoelectronic applications, ideal Greek cross‐dipole (α = 90°) stacking of chromophores remains elusive. We report a novel Greek cross (+) assembly of 1,7‐dibromoperylene‐3,4,9,10‐tetracarboxylic tetrabutyl...

Question
It is said that in multi layer graphene sheets, the charge carrier mobility is affected due to the charge impurity scattering, compared to mono layer sheets. Please help me to understand the term charged impurity scattering.
