A Tetrathiafulvalene‐Functionalized Radiaannulene with Multiple Redox States

Abstract

Mannigfache Zustände: Durch Anbringen zweier Tetrathiafulvalen(TTF)‐Einheiten an einem expandierten Radiaannulen(RA)‐Kern erhält man ein Molekül, das in mehreren Redoxzuständen mit charakteristischen UV/Vis/IR‐Absorptionen existieren kann. Ein niederenergetischer Intervalenzübergang belegt, dass das Radikalkation gemischte Valenzzustände (MV) aufweist.

Tuning crystal polymorphs of a π-extended tetrathiafulvalene-based cruciform molecule towards high-performance organic field-effect transistors

“…Different from the one-dimensional TTF-based molecules widely investigated in the past, we focused on combining dithiafulvene (DTF; "TTF half unit") and other functional molecular units to design cruciform-like molecular structures (that is, two orthogonally oriented π-systems). One aim was to achieve good and tunable conducting properties by virtue of the different conjugation pathways that exist between the individual parts of the molecule [17][18][19][20][21][22][23]. These DTF-based cruciform molecular wires have demonstrated potential promising applications in molecular electronics and also provided a good platform for the investigation of the dependence of conducting properties on their molecular structures [24][25][26].…”
