Color–Tunable Triple–State “Smart” Window
Advanced Photonics Research, 2021 Materials that rapidly change their optical properties in response to external stimuli are crucial for displays and “smart” window applications. Herein, a fluorescent red dye modified with liquid crystal (LC) side chains is described to be interactive ...

Time-Dependent Density Matrix Renormalization Group Algorithms for Nearly Exact Absorption and Fluorescence Spectra of Molecular Aggregates at Both Zero and Finite Temperature [PDF]
, 2018 We implement and apply time-dependent density matrix renormalization group (TD-DMRG) algorithms at zero and finite temperature to compute the linear absorption and fluorescence spectra of molecular aggregates.

Observation of Two-Exciton States in Perylene Bisimide Aggregates
EPJ Web of Conferences, 2013 The behavior of excitons on perylene bisimide aggregates is investigated at high excitation densities by femtosecond absorption spectroscopy. Indications for a significant population in the two-exciton manifold are found.

Perylene Bisimide Cyclophanes: Structure–Property Relationships upon Variation of the Cavity Size
Organic Materials, 2020 Five cyclophanes composed of two perylene bisimide (PBI) dyes and various CH2–arylene–CH2 linker units were synthesized. PM6-D3H4 geometry-optimized structures and a single crystal for one of these cyclophanes reveal well-defined distances between the ...

Reversible Photoreduction as a Trigger for Photoresponsive Gels [PDF]
, 2016 We present here a new type of photoresponsive, reversible low molecular weight gel. All previous examples rely on a photoisomerisation, ring-closing or dimerization. We show that photoreduction of a perylene bisimide gelator results in the formation of a

Controlled aggregation of peptide-substituted perylene-bisimides [PDF]
Chemical Communications, 2012 Controlled aggregation of perylene bisimides in multiple modes has been achieved via symmetric substitution with peptides. Using optical probes of aggregation, the balance of hydrophobic and electrostatic forces are found to play a key role in directing self assembly and are exploited via solvent, pH, and specific extrinsic ion effects.

Iridium-Catalyzed Direct Tetraborylation of Perylene Bisimides [PDF]
Organic Letters, 2011 Treatment of perylene bisimides (PBIs) with bis(pinacolato)diboron in the presence of an iridium catalyst provides tetraborylated PBIs at 2,5,8,11-positions in good yields with perfect regioselectivity. The planar structure of the perylene core has been confirmed by X-ray diffraction analysis.
