Effect of bridge on energy transfer and photoinduced charge separation in perylene-diimide-naphthalene-bisimide-hexathiophene based donor-bridge-acceptor triads

EPJ Web of Conferences, 2013
Femtosecond transient absorption spectroscopy is performed to assess bridge effects on energy transfer and charge separation in molecular junctions. A short, conjugated bridge can facilitate charge separation from both donor and acceptor, whereas in ...

Silanediol-Bay-Bridge Rigidified Axially Chiral Perylene Bisimide [PDF]

The Journal of Organic Chemistry
Chiral organic molecules with a complementing π-structure are highly desired to obtain materials with good semiconducting properties and pronounced chirality effects in the visible region. Herein, we introduce a novel design strategy to achieve an axially chiral and rigid perylene bisimide (PBI) dye by attaching the chirality-inducing 2,2'-biphenoxy ...

Controlled Aggregation of Peptide Substituted Perylene-Bisimides [PDF]

, 2021
<p>In recent years there has been an intersection of supramolecular chemistry and materials science, with a particular focus on the controlled self-assembly of functional building blocks. The impetus for assembly of organised architectures is a requirement due to organic electronic device performance being sensitive to the geometric configuration

Beyond Covalent Crosslinks: Applications of Supramolecular Gels [PDF]

, 2018
Traditionally, gels have been defined by their covalently cross-linked polymer networks. Supramolecular gels challenge this framework by relying on non-covalent interactions for self-organization into hierarchical structures.

Organic‐Inorganic Photosynthetic Interfaces Built on Intertwined WO3 Nanosheets for Enhanced HBr/H2O Photoanodic Oxidations

Advanced Energy and Sustainability Research, Volume 6, Issue 11, November 2025.
Three‐dimensional WO3 nanosheets (3D‐NS) with exposed {001} facets are grown in situ, forming a highly interconnected 3D architecture, which is sensitized with a polymeric perylene bisimide layer and test for HBr photooxidation. The self‐assembly of a quantasome architecture—based on perylene bisimide dyes, templated around a tetra‐ruthenated ...

Laser Control of Dissipative Two-Exciton Dynamics in Molecular Aggregates

, 2012
There are two types of two-photon transitions in molecular aggregates, that is, non-local excitations of two monomers and local double excitations to some higher excited intra-monomer electronic state.
