Herein, the microscopic and spectroscopic characterization of a novel non‐covalent electron donor−acceptor system, in which three different metalloporphyrins (1, 2, and 3) play the dual role of light harvester and electron donor with SWCNTs as electron acceptor, is described. To this end, microscopy, that is, atomic force microscopy (AFM) and transmission electron microscopy (TEM) corroborate the...
Here, the ability of a novel near‐infrared dye to noncovalently self‐assemble onto the surface of single‐walled carbon nanotubes (SWCNTs) driven by charge‐transfer interactions is demonstrated. Steady‐state, Raman, and transient absorption spectroscopies corroborate the electron donating character of the near‐infrared dye when combined with SWCNTs, in the form of fluorescence quenching of the excited...
The optical properties of perylene bisimide dyes (PBI) are strongly aggregation dependent. Thus, PBIs are perfect candidates for probing interdye interactions immobilized onto nanoparticle surfaces. The synergetic interplay of different spectroscopic techniques and molecular dynamics simulations gives insights into the aggregation in the form of H‐aggregates. Overall, the conclusions presented in...
Precise control over the ratio of perylene bisimide (PBI) monomers and aggregates, immobilized on alumina nanoparticle (NP) surfaces, is demonstrated. Towards this goal, phosphonic acid functionalized PBI derivatives (PA‐PBI) are shown to self‐assemble into stoichiometrically mixed monolayers featuring aliphatic, glycolic, or fluorinated phosphonic acid ligands, serving as imbedding matrix (PA‐M)...
