Azuperylene: The Non‐Alternant Isomer of Perylene.
Liu, Shengpei; Díaz-Fernández, Marcos; Zhang, Menglin; Huang, Fei; Chen, Yong; Yang, Yudong; Marín-Beloqui, José Manuel; Lan, Jingbo; You, Jingsong; Casado-Cordón, Juan
; Zhang, Cheng[et al.] (Wiley, 2025-05-13)
The isoelectronic isomer of perylene, hereafter called as azuperylene, has been prepared. Electronic structure analysis reveals that the new isomer can be described as a union of two antiparallel azulenes in which the ... -
Dynamic Electrochemistry of Anthanthrone.
Cárdenas Valdivia, Abel; Lirette, Fréderic; Marín-Beloqui, José Manuel; Casanova, David; Morin, Jean-François; Casado-Cordón, Juan[et al.] (2023)
In this investigation, we present a “nanographene” based on the low-cost commercially available 4,10-dibromoanthanthrone building block, where the anthanthrone core can be viewed as a fusion of two anthracene moieties with ... -

Non-Kasha phosphorescence: the role of azulene and carbazole.
Organic electronics have the capabilities to replace inorganic semiconductors in electronic devices. Hence, it is important to pay attention to organic molecular structure, i.e. π conjugation and aromaticity, to achieve ... -
Nongeminate Recombination Dynamics–Device Voltage Relationship in Hybrid PbS Quantum Dot/C60 Solar Cell
(American Chemical Society, 2013-08-05)Here we employ transient optoelectronic techniques to study the charge present in the device and the nongeminate recombination rate in hybrid PbS/C60 planar heterojunction solar cells under working conditions. We find ... -
Optimal Synergy between Azulenes and Acenes in Azuacenes with 6‑7‑5 Ring Topology
(ACS, 2025-01-07)Azuacenes, defined as azulene fused with acenes in a 6-7-5 ring topology and spanning lengths from 3 to 6 rings, have been synthesized using a new skeleton editing and [3 + 2] annulation synthesis protocol as a distinction ... -
The heteroatom effect in ambipolar diradicals.
Moles Quintero, Sergio; Harbuzaru, Alexandra; Marín-Beloqui, José Manuel; González Núñez, Raúl; Ponce-Ortiz, Rocío; Casado-Cordón, Juan[et al.] (2023)
The ability to efficiently transport both holes and electrons makes ambipolar organic materials appealing architectures in organic electronics for the development of p- and n-channel devices. However, most of the organic ... -
Transient Absorption Spectroscopy (TAS) for the study of organic materials for energy conversion
Marín-Beloqui, José Manuel; Casado-Cordón, Juan (2022-03)
Transient Absorption Spectroscopy (TAS) is a pump probe technique with the ability of directly probe the photogenerated species and their evolution with time. This technique consists in two light sources, one of them ... -
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 ... -
Triplet-charge annihilation in a small molecule donor: acceptor blend as a major loss mechanism in organic photovoltaics
Marín-Beloqui, José Manuel; Casado-Cordón, Juan (2022-06-23)
Organic photovoltaics (OPV) are close to reaching a landmark 20% device efficiency.[1] One of the proposed reasons that OPVs have yet to attain this milestone is their propensity toward triplet formation. In this ... -
Truncated conjugation in fused heterocycle-based conducting polymers: when greater planarity does not enhance conjugation.
(2023-07-03)One of the main assumptions in the design of new conjugated polymer materials for their use in organic electronics is that a higher coplanarity leads to greater conjugation along the polymer backbone. Conventionally, a ... -
Use of Transient Absorption Spectroscopy to Probe Unexpected Phenomena in Organic Electronics
(2024-01-23)Organic photovoltaics have the capability to overcome to their inorganic counterparts due to several reasons like low weight, flexibility and low price. Transient Absorption Spectroscopy (TAS) represents the perfect tool ... -
