A Trapezoidal Octacyanoquinoid Acceptor Forms Solution and Surface Products by Antiparallel Shape Fitting with Conformational Dipole Momentum Switch
(Wiley, 2021-06-04)A new compound (1) formed by two antiparallelly disposed tetracyano thienoquinoidal units has been synthesized and studied by electrochemistry, UV/Vis-NIR, IR, EPR, and transient spectroscopy. Self-assembly of 1 on a ... -
Dibenzoquinone cyclopentadithiophene diradicaloids show optical transitions of different spin states and anomalous near-infrared emission
Privado, María; Moles Quintero, Sergio; Barrejón, Myriam; De-la-Cruz, Pilar; Janaarthana Babu, P.M.; Casanova, David; Langa, Fernando; Casado-Cordón, Juan
[et al.] (Wiley, 2024)
We have prepared a series of bis(semiquinone) compounds with dithiophene bridges of different length that evolve from closed-shell (smaller compound) to full diradical (longer compound) for which the narrow singlet-triplet ... -
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 ... -
Folded–twisted mechanisms control dynamic redox properties, photophysics and electron transfer of anthanthrene-quinodimethanes
Cárdenas Valdivia, Abel; Lirette, Fréderic; Marín-Beloqui, José M.; Carreras, Abel; Casanova, David; Boismenu-Lavoie, Joël; Morin, Jean-François; Casado-Cordón, Juan[et al.] (RSC, 2025-01)
The synthesis, electrochemical, spectroelectrochemical, photophysical and light induced electron transfer reactions in two new anthanthrene quinodimethanes have been studied and analyzed in the context of dynamic ... -
Raman spectroscopy as a versatile tool to study organic biradicals
Casado-Cordón, Juan; Zafra-Paredes, Jose Luis; Casanova, David; Zhu, Xiaozhang; Medina Rivero, Samara (2019-07-05)
Since -conjugated organic molecules were probed as potential semiconducting materials, suitable for replacing the widely used silicon technologies, their structural, optical and conductive properties have been under study ... -
V shaped Tröger oligothiophenes boost triplet formation by ct mediation and symmetry breaking
Medina Rivero, Samara; Alonso-Navarro, Matías J.; Tonnelé, Claire; Marín-Beloqui, José Manuel; Suarez-Blas, Fátima; Clarke, Tracey M.; Kang, Seongsoo; Oh, Juwon; Ramos, M. Mar; Kim, Dong-Ho; Casanova, David; Segura, José L.; Casado-Cordón, Juan[et al.] (ACS, 2023-12-20)
A new family of molecules obtained by coupling Tröger's base unit with dicyanovinylene-terminated oligothiophenes of different lengths has been synthesized and characterized by steady-state stationary and transient ...
