• (CT) process between the framework and the guest molecules is a crucial step towards the design of new electroactive MOFs. Herein, we present the encapsulation of fullerenes (C60) in a mesoporous tetrathiafulvalene (TTF)-based MOF. The CT process between the electron-acceptor C60 guest and the

• constituents of CT crystals thus form a specific subset. We name a few examples. On the Au(111) surface, ordered monolayers were observed for following donor/acceptor pairs: tetrathiafulvalene (TTF)/7,7,8,8-tetracyanoquinodimethane (TCNQ) [11][12], tetramethyltetrathiafulvalene (TMTTF)/TCNQ [13], α

• combination with tetrathiafulvalene (TTF) on Au(111). TNAP is a flat planar molecule (C2h) with the ability to delocalize unpaired electrons in a charge-transfer complex [26]. We note that the crystal structure of TNAP is unknown and, as a consequence, we cannot compare the packing of TNAP on the Ag(100

• decrease of bending radius. While amounting to 0.1 cm2/Vs for unbent structures, its magnitude decreases to ca. 0.06 cm2/Vs for r = 25 mm and to 0.04 cm2/Vs for r = 5 mm [18]. This effect has been attributed to the influence of stress induced in the tetrathiafulvalene (TTF) semiconductor crystalline films

• and the corrugated surface can significantly alter the microstructure of semiconducting films and bring about a decrease of the device performance [18]. The effect of surface energy on charge-carrier mobility was discussed above using an example of transistors made of tetrathiafulvalene (TTF

• tetrathiafulvalene (TTF) as RM with redox potentials, TTF/TTF+ and TTF+/TTF2+, of 3.4 to 3.7 V. With TTF in a DMSO:LiClO4 electrolyte the Li/O2 cells showed a Type 1C hysteresis and significantly improved kinetics for the charge process. In addition e−/O2 ratios very close to two, as expected for Li2O2 oxidation
