Four novel electron-withdrawing/donating groups-graphene-oxide-oxidized-multiwalled carbon nanotubes (EWG/EDG-GO-o-MWCNTs) nanocomposites were synthesized via Aldol reaction. The EWG and EDG were successfully grafted onto GO-o-MWCNTs, which were investigated by fourier transform infrared spectroscopy (FT...
Two-photon absorption cross-sections of about 160GM were observed when two electron-withdrawing groups are linked to the imidazo[4,5- b ]pyridine core, elucidating a path to achieve high optical nonlinearities in imidazopyridine derivatives. Furthermore, a increase in the two-photon cross-section...
In this study, the ability of electron-donating (hydroxyl) and electron-withdrawing (nitro) groups on the phenyl ring of Phe to affect the interactions between the peptide and SWNTs is examined by substituting the Phe residues in the nano-1 sequence with tyrosine and p-nitro-phenylalanine, ...

Regiocontrol by electron withdrawing groups in the Rh-catalyzed CH insertion of ??-diazoketones It is possible to control the regiochemistry of the Rh-catalyzed insertion of α-diazoketones into C H bonds by taking advantage of the greatly reduced rat......

Especially, the influence of electron-withdrawing/-donating groups on the carrier dynamics in device has not been studied. PSCs photovoltaic properties directly interact with the excited charge-carriers (electrons and holes) interaction through dielectric screening. Therefore, fully understanding of the ...
