Phase behavior and electrical transport in DBTTF-HATCN donor-acceptor mixtures
Andreas Opitz, Hongwon Kim, Dmitry Lapkin +10
The formation of donor-acceptor complexes (DACs) between the electron donor Dibenzotetrathiafulvalene (DBTTF) and the acceptor Hexaaza\-triphenylene\-hexacarbo\-nitrile (HATCN) res…
Disclosing the Impact of Local Host Effects on TADF Dynamics
Björn Ewald, Theodor Kaiser, Thomas Fleischmann +1
Donor-acceptor (D-A) type thermally activated delayed fluorescence (TADF), a key technology of proposed Gen3 organic light emitting diodes (OLEDs), is highly sensitive to the rigid…
Unveiling the Role of Solvents in DBTTF:HATCN Ternary Cocrystals
Ana M. Valencia, Lisa Schraut-May, Marie Siegert +7
Donor-acceptor (D:A) cocrystals offer a promising platform for next-generation optoelectronic applications, but the impact of residual solvent molecules on their properties remains…
Probing plexciton dynamics with higher-order spectroscopy
Simon Büttner, Luca Nils Philipp, Julian Lüttig +5
Coupling molecular transition dipole moments to surface-plasmon polaritons (SPPs) results in the formation of new optical quasiparticles, i.e., plexcitons. Mixing the specific prop…
How to Fix Silver for Plasmonics
Björn Ewald, Leo Siebigs, Cheng Zhang +9
Silver (Ag) is considered an ideal material for plasmonic applications in the visible wavelength regime due to its superior optical properties, but its use is limited by the poor c…
Frontier orbitals control dynamical disorder in molecular semiconductors
Alexander Neef, Sebastian Hammer, Yuxuan Yao +11
Charge transport in organic semiconductors is limited by dynamical disorder. Design rules for new high-mobility materials have therefore focused on limiting its two foundations: st…
