    Notes: Abstract The use of (tetrakis(4-hexylphenyl)porphyrinato)Fe(II) in polymerization reactions with bidentate ligands such as 9,10-diisocyanoanthracene and 1,4-diisocyanobenzene led to well-defined stacked polymers1 and2 which are still soluble in common organic solvents such as chloroform, dichloromethane, and tetrahydrofurane. They have been completely characterized by1H-NMR and UV/vis spectropscopy in solution, even allowing end-group analysis for determination of the average degree of polymerization, yieldingn=10 andn=5 for1 and2, respectively. Mößbauer and IR spectroscopy further established the strong Fe-CN bonding reflected by very small isomer shifts and quadrupole splittings (ΔE Q∼0.2 mm s−1) and a large decrease in the IR stretching frequency (Δv CN∼60 cm−1). The axially stacked polymers exhibit semiconducting properties only upon doping.

    Synthesis of new soluble triphenodithiazines and investigation of their donor properties (1992)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 125 (1992), S. 1495-1500

    Notes: The syntheses of 6 and 7, starting from 3,6-dichloro-2,5-bis(2-thioanisido)-1,4-benzoquinone (4), are reported. The solid-state conformations of 6 and 7 are elucidated by X-ray structure analysis, and the cyclovoltammetric investigation of 6 and 7 in solution shows low and reversible oxidation half-waves for both compounds. The relatively high oxidation potentials of 7 compared to 6 are related to their conformational features. EPR measurements on the radical cations derived from 6 and 7 both suggest a planarized conformation of these species. Oxidation of 6 with strong oxidants leads quantitatively to the quinoid triphenodithiazine 8, whereas the charge-transfer complex formed between 7 and DDQ exhibits semiconducting properties.
