Exciton migration in self-assembled dendrite-type fractal superstructures of mo...
Bernardo, César; Belsley, M.; Coutinho, Paulo J. G.; Schellenberg, Peter; Moura, Isabel; Núñez Fernández, Yuriel; Stauber, Tobias; Vasilevskiy, MikhailWe investigated dendrite shaped superstructures made of two different QDs, namely CdSe/ZnS and CdTe. Due to the dense packing of QDs, Förster resonance energy transfer (FRET) may compete with deexcitation, and the specific dendrite shaped structure suggests the possibility of funneling of excitation from the edges of the structure to the center.
Synthesis of beta-carboline derivatives
Bernardo, César; Olival, Ana Cristina Dias; Ribeiro, António; Rodrigues, L. R.; Esteves, Ana Paula; Campos, Ana M. F. OliveiraThe preparation of b-carbolines and of three alkynyl esters, two of them derived from carbolines, is described. Two new glycoconjugates were obtained, one by a click approach from an alkynyl derivative with tetracetyl-b-D-glucosylazide and the other one by linking a carboline carboxylic acid with tetracetyl-b-D-glucosylamine.
