The effect of hydrogen bond interactions on the electronic nature of DPP-based organic semiconductors: implications on charge transport
González Núñez, Raúl; Martínez, Gabriel; Ávila-Rovelo, Nelson Ricardo; Hong, Kyeog-Im; Ruiz-Carretero, Amparo; Ponce-Ortiz, Rocío
[et al.] (Royal Society of Chemistry, 2024-12)
In this work, we show that hydrogen bond interactions, in addition to directing supramolecular order, can have an intriguing effect on the molecular and electronic properties of DPP derivatives, facilitating redox processes ... -
The fluorination effect: the importance of backbone planarity in achieving high performance ambipolar field effect transistors
(RSC, 2022-01-12)We report here the synthesis and physico-chemical characterization of a series of donor–acceptor (D–A) copolymers consisting of 4,7-di(2-thienyl)-2,1,3-benzothiadiazole and isoindigo building blocks, which have been ... -
Triplet formation inhibits amplified spontaneous emission in perylene-based polycyclic aromatic hydrocarbons
Moles Quintero, Sergio; Mira-Martínez, Jose C.; Zou, Ya; Díaz-Fernández, Marcos; Boj, Pedro G.; Wu, Jishan; Díaz-García, María A.; Marín-Beloqui, José Manuel; Casado-Cordón, Juan[et al.] (2024-02-26)
Polycyclic aromatic hydrocarbons (PAHs) have demonstrated potential as active laser materials, showing good amplified stimulated emission (ASE) properties. However, the molecular origin of their ASE properties is still ... -
Tunable electroactive oligothiophene-naphthalimide semiconductors via end-capped engineering: cumulative effects beyond the linker
Alonso-Navarro, Matías J.; Harbuzaru, Alexandra; González Núñez, Raúl; Ramos, M. Mar; Segura, José L.; Ponce-Ortiz, Rocío[et al.] (RSC, 2023-08)
Aiming to obtain novel functional semiconducting materials for their use in organic electronics, the combination of strong donor moieties with electron-withdrawing units is one of the most useful strategies to obtain ... -
Tuning the charge stabilization and transport in naphthalimide-based semiconductors via a fused-ring and core-engineering strategy
González-Núñez, Raúl; Alonso-Navarro, Matías J.; Suarez-Blas, Fátima; Gala, Elena; Ramos, M. Mar; Segura, José L.; Ponce-Ortiz, Rocío[et al.] (2024-03-24)
The synthesis and characterization of a family of rationally designed compounds based on naphtha- limide units attached, through conjugated nitrogenated linkers (i.e. pyrazine and imidazoline units), to fused thiophene-based ... -
Tuning the Diradical Character of Indolocarbazoles: Impact of Structural Isomerism and Substitution Position
