Spectral studies of the bis-linked tetrathiafulvalenes to [60]fullerene

Small Noncytotoxic Carbon Nano‐Onions: First Covalent Functionalization with Biomolecules

“…the IR spectroscopic characterization of functionalized SWNTs, [19,20] the band detected at 1540 cm À1 was attributed to the C=C stretching vibration of functionalized carbons. [21][22][23] The À1 were assigned to the n C=O mode and defined as the "amide I" band and to the NÀH bending vibration d NÀH defined as the "amide II" band, respectively. The intensity of the N À H bending absorption is considerably weaker then the carbonyl absorption.…”

Femtosecond time-resolved electronic relaxation dynamics in tetrathiafulvalene

“…10 One of the fundamental issues in designing molecular systems for photoinduced charge separation is to investigate the primary photophysical relaxation mechanism. Spectral studies of fullerenes functionalized by TTF derivatives have been reported in the ultraviolet (UV) range, 12 as well as picosecond time-resolved absorption spectra. 13,14 Both the donor-acceptor system and the oligothiophene alone have been studied in the liquid phase by femtosecond time-resolved spectroscopy.…”

“…13,14 Both the donor-acceptor system and the oligothiophene alone have been studied in the liquid phase by femtosecond time-resolved spectroscopy. 15 For many of these photoactive compounds, which are formed by Van der Waals polarization interactions, 12 the Highest Occupied Molecular Orbital (HOMO) is localized primarily on the TTF moiety while the lowest unoccupied molecular orbital (UMO) resides on the acceptor moiety. 16 Photoexcitation in the visible range triggers a fast energy transfer from TTF to the acceptor moiety before the appearance of a charge transfer process on the picosecond time-scale.…”
