Application of triaminomethane derivative as n-type dopant in semiconductor material

The invention discloses an application of a triaminomethane derivative as an n-type dopant in a semiconductor material. According to the invention, the triaminomethane derivative used as the n-type dopant of semiconductor materials such as organic semiconductors, carbon nanotubes, two-dimensional semiconductor materials and the like has the advantages of high stability, high solubility and high doping capacity, has good miscibility with organic semiconductor materials, cannot damage a pi-pi accumulation channel of polymer transmission charges by doping, and can be used for processing the dopedsemiconductor thick film with high performance; and by using the triaminomethane derivative as an n-type dopant to be applied to photoelectric devices such as thin film transistors, thermoelectric materials, solar cells, light emitting diodes and the like, the electron density of bulk phases or interfaces of semiconductor materials can be greatly improved, the resistance and contact potential barriers of the bulk phases or the interfaces are reduced, and the n-type conductivity and power factors of the materials are improved.

Group Transfer Reactions. - Tetracarbonylferrates from Orthoformic Acid Derivatives and Pentacarbonyliron

The nucleophilic leaving group X is transferred from orthoformic acid derivatives HC(NR2)X (X= NR2, OR, CN) to Fe(CO)5.No such reactions were observed between 4 and amide acetals (HCX2NR2) or ortho ester derivatives HCX3 (X= OR, SR).The structures of the transition metal-acyl complexes obtained have been determined by IR and NMR spectra.In the case of the reaction of tris(dimethylamino)methane (3a) with 4 the equilibrium between the resulting amidinium-carbamoyltetracarbonylferrate complex 5a and the starting materials was investigated.The equilibrium is shifted completely in favor of the ionic compound 5a.However, 3a could be isolated by extraction of this solution with an apolar solvent.Alkylation of 5a with triethyloxonium tetrafluoroborate leads to the tetracarbonyliron-carbene complex 13.Reaction of 5a with acrylonitrile or methyl acrylate by addition of both the nucleophile "NR2-" and the electrophile + and subsequent eliminations gives the β-dimethylamino substitution product 18 and 21, respectively.In contrast 3a induces polymerisation of acrylonitrile.
