Mateos Gil, Jaime ; Calbo, Joaquín ; Rodríguez Perez, Laura ; Herranz, M.Angeles ; Ortí, Enrique ; Martín, Nazario | Wiley-VCH | 2019Fullerene receptors prepared by a twofold CuI -catalyzed azide-alkyne cycloaddition (CuAAC) reaction with ?-extended tetrathiafulvalene (exTTF) have been covalently linked to singlewalled carbon nanotubes (SWCNTs) and multi-walled carbon nanotub[...]texto impreso
Gallego, María ; Calbo, Joaquín ; Krick Calderón, Rafael M. ; Pla, Paula ; Hsieh, Ya-Chu ; Pérez, Emilio M. ; Wu, Yao-Ting ; Ortí, Enrique ; Guldi, Dirk M. ; Martín, Nazario | Wiley Online Library | 2017-02Abstract: The association behavior of an electron-donating, bowl-shaped, truxene-based tetrathiafulvalene (truxTTF) with two corannulene-based fullerene fragments, C32H12 and C38H14, is investigated in several solvents. Formation of 1:1 complex[...]texto impreso
Moreira, Luis ; Calbo, Joaquín ; Aragó, Juan ; Illescas, Beatriz M. ; Nierengarten, Iwona ; Delavaux-Nicot, Béatrice ; Ortí, Enrique ; Martín, Nazario ; Nierengarten, Jean-Françoise | ACS | 2016-09Two new conjugated porphyrin-based systems (dimers 3 and 4) endowed with suitable crown ethers have been synthesized as receptors for a fullerene-ammonium salt derivative (1). Association constants in solution have been determined by UVvis titra[...]texto impreso
Sandoval Torrientes, Rafael ; Calbo, Joaquín ; Matsuda, Wakana ; Choi, Wookjin ; Santos, José ; Seki, Shu ; Ortí, Enrique ; Martín, Nazario | Wiley-VCH | 2017A series of donor–acceptor small molecules based on electrondeficient benzothiadiazole (BTD) and electron-rich benzodithiophene (BDT) featuring an A-D-A structure is presented. Exhaustive spectroscopic, electrochemical, and computational studies[...]texto impreso
Zimmermann, Iwan ; Urieta Mora, Javier ; Gratia, Paul ; Aragó, Juan ; Grancini, Giulia ; Molina-Ontoria, Agustín ; Ortí, Enrique ; Martín, Nazario ; Khaja Nazeeruddin, Mohammad | Wiley Online Library | 2016-11-21The synthesis and characterization of a series of novel small-molecule hole-transporting materials (HTMs) based on an anthra[1,2-b:4,3-b?:5,6-b??:8,7-b???]tetrathiophene (ATT) core are reported. The new compounds follow an easy synthetic route a[...]texto impreso
Moreira, Luis ; Calbo, Joaquín ; Illescas, Beatriz M. ; Aragó, Juan ; Nierengarten, Iwona ; Delavaux-Nicot, Béatrice ; Ortí, Enrique ; Martín, Nazario ; Nierengarten, Jean-Françoise | Wiley-VCH | 2015A fullerene-ammonium derivative has been combined with different metalloporphyrin-crown ether receptors to generate very stable supermolecules. The combination of fullerene-porphyrin and ammonium-crown ether interactions leads to a strong chelat[...]texto impreso
Sandoval Torrientes, Rafael ; Gavrik, Alexey ; Isakova, Anna ; Abudulimu, Abasi ; Calbo, Joaquín ; Aragó, Juan ; Santos, José ; Ortí, Enrique ; Martín, Nazario ; Dyakonov, Vladimir ; Lüer, Larry | Royal Soc. Chemistry | 2019Small-molecule-based organic solar cells (OSCs) are a recurrent alternative to polymer-based OSCs. Due to the higher purity and definition of small molecules compared to polymers, the morphological requirements can be more relaxed. Here, we pres[...]texto impreso
Garrido, Marina ; Calbo, Joaquín ; Rodríguez Perez, Laura ; Aragó, Juan ; Ortí, Enrique ; Herranz, M.Angeles ; Martín, Nazario | RSC | 2017Graphene nanobuds were prepared via the non-covalent anchoring of C60-based molecules endowed with one or three pyrene units. TGA, FTIR, UV-Vis and TEM investigations confirmed the nanohybrids formation. For the two molecular derivatives, striki[...]texto impreso
García, Raúl ; Calbo, Joaquín ; Viruela, Rafael ; Herranz, Maria Ángeles ; Ortí, Enrique ; Martín, Nazario | Wiley Online Library | 2018Donor-acceptor alkynes, endowed with 11,11,12,12-tetracyano-9,10-anthraquinodimethane (TCAQ) and N,N-dimethylaniline (DMA) units, have been further functionalized by a [2+2] tetracyanoethylene (TCNE) cycloaddition followed by a subsequent retroe[...]texto impreso

Moreira, Luis ; Calbo, Joaquín ; Krick Calderón, Rafael M. ; Santos, José ; Illescas, Beatriz M. ; Aragó, Juan ; Nierengarten, Jean-Françoise ; Guldi, Dirk M. ; Ortí, Enrique ; Martín, Nazario | RSC | 2015A series of exTTF-(crown ether)2 receptors, designed to host C60, has been prepared. The size of the crown ether and the nature of the heteroatoms have been systematically changed to fine tune the association constants, which were determined by [...]
