Synthesis, crystal structure and photoconductivity of new molecular complex of C60 with tetrabenzo(1,2-bis[4H-thiopyran-4-ylidene]ethene): Bz4BTPE C60

Novel fullerene-functionalised poly(terthiophenes)

“…6(b)) exhibited a peak at 320 nm (due to C 60 ), a shoulder of absorption at $440 nm (due to p-p* transition) and a loss of the free carrier tail at longer wavelengths, indicative of complete reduction. The UV-Vis spectrum of poly(TTh-BB) at reduced state matches well with the UV-Vis spectrum of pure C 60 [27] in terms of the absorption peak due to C 60 . In addition to the UV-Vis characterisations carried out on oxidised and reduced P(TTh-BB), the color of the fully oxidised homopolymer was dark green, while it was light yellow when fully reduced.…”

Synthesis, Crystal Structures, Magnetic Properties and Photoconductivity of C60 and C70 Complexes with Metal Dialkyldithiocarbamates M(R2dtc)x, where M = CuII, CuI, AgI, ZnII, CdII, HgII, MnII, NiII, and PtII; R = Me, Et, and nPr

“…Photoexcitation of Cu(Et 2 dtc) 2 contributes to photoconductivity of 1 and 2 since this donor has intense absorption in the visible range. A similar mechanism was observed in Bz 4 BTPE·C 60 {Bz 4 BTPE: tetrabenzo[1,2-bis(4H-thiopyran-4-ylidene)ethane]}, [62] and conjugated polymer-fullerene composites. [63] CT from donor to fullerene molecules contributes to photoconductivity of the complexes with relatively intense CT bands in the visible-NIR range: 7 and TBPDA·(C 60 ) 2 (N,N,NЈ,NЈ-tetrabenzyl-pphenylenediamine).…”

“…Hexagonal or triclinic elementary cell was assumed as initial state for LCV·C 60 crystal, monoclinic for Bz4BTPE·C 60 (molecule is ordered whereas C60 one is statistically disordered and was refined as a superposition of two orientations with 13:7 occupancy) [2], triclinic for LMG·C 60 [3]. Initial data preparation and intermediate transformations were carried out using original software.…”
