Abstract: The synthesis, characterization, ultrafast dynamics, and nonlinear spectroscopy of 30 nm nanospheres of brilliant green-bis(pentafluoroethylsulfonyl)imide ([BG][BETI]) in water are reported. These thermally stable nanoparticles are derived from a group of uniform materials based on organic salts (nanoGUMBOS) that exhibit enhanced near-infrared emission compared with the molecular dye in water. The examination of ultrafast transient absorption spectroscopy results reveals that the overall excited-state relaxati… Show more

“…We have previously investigated the ultrafast excited-state dynamics of different types of nanoGUMBOS using transient absorption spectroscopy. , In one study, we reported observation of tunable intermolecular energy transfer in crystalline ruthenium bipyridine-–bis­(pentafluoroethylsulfonyl)­imide ([Ru­(bipy) 3 ]­[BETI] 2 ) nanoGUMBOS in colloidal suspension in water . Size-dependent relaxation dynamics were observed in these nanoGUMBOS, characterized by decay dynamics similar to the Ru­(bipy) 3 Cl 2 dye with an added relaxation pathway from intermolecular energy transfer .…”

“…T.E. Karam et al [127] introduced thermally stable, brilliant green-based nanoGUMBOS [BG][BETI] (BG = brilliant green) ( Figure 17 MIPs (molecularly imprinted polymers) exhibited property of molecular separation and sensing while inferring of electrostatic/hydrogen bonding under aqueous medium has become a major problem. To overcome this drawback of conventional MIPs, S. Hamdan et al [128] introduced four NGMIPs (nano-GUMBOS molecular imprinted polymers) that applied in the enantiorecognition for chiral amino acids (D-and L-tryptophane) ( Table 3, Entry 15-18).…”
