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
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

Since their discovery, crown ethers as well as the most recent carbon nanostructures, namely fullerenes, carbon nanotubes, and graphene, have received a lot of attention from the chemical community. Merging these singular chemical structures by [...]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 [...]
