Cadmium-113 n.m.r . spectra at 66.6 MHz of various mixtures of the six cage compounds [X4M10( SPh )16]4- (1; X = S, Se; M = Zn, Cd ) and [M4( SPh )10]2- (M = Zn, Cd ), have revealed the exchange reactions of M and of X which occur within the different structural elements of (1), namely the triply bridging chalcogenide ligands X, the inner metal atoms Mi, and the outer metal atoms Mo. At laboratory temperature the exchange time scales range from days (X) through hours (Mi) to seconds (Mo and SPh ), according to the extent of atomic connection to each of these structural components of the aggregate. Metal exchange does not always follow random statistics, with biases towards equilibrium association of the same metal. The M- and X-substituted products, with lower symmetry than the high-symmetry precursors, reveal the mutual influences of the various structural elements on Cd chemical shift: S → Se substitution causes changes ( ΔδCd ) of -37 ppm at one bond, -3 ppm and -1.5 ppm at three bonds, and + 1 ppm five bonds distant; Cd → Zn substitution causes δCd to change by + 13 ppm and + 5 ppm at a connection of two bonds and by -3 ppm over four bonds. These effects of adjacent Cd → Zn substitution on δCd provide well defined models in support of the hypothesis of similar effects in the Cd n.m.r . spectra of mixed Zn, Cd metallothionein proteins.

The Relationship

The relationship between molecular geometries, crystal structures and charge mobilities of hexathiapentacene (HTP) and its three derivatives (2Se-HTP, 4Se-HTP, 6Se-HTP) were studied with density functional theory combined with hopping mechanism in the molecular and crystal level. The effect of Se substitution on the charge mobility was discussed. The calculated results showed that the derivatives exhibit good planarity and the molecular geometries have little variation during the charge transfer process. The electron mobility is 1.20 cm2 V?1 S?1 for HTP and 2.30 cm2 V?1 S?1 for 6Se-HTP, which are much larger than the corresponding hole ones, indicating that HTP and 6Se-HTP are good candidates for n-type organic semiconductor. However, 2Se-HTP and 4Se-HTP have comparable hole and electron mobilities and are suitable for ambipolar semiconductor.
