Dinaphthosilole organic photoelectric functional material and synthesis method thereof

The invention discloses a dinaphthosilole organic photoelectric functional material. The functional material is synthesized mainly through the following steps: synthesizing a zirconium heterocycle performing water-free and oxygen-free reaction on bis-substituted internal alkyne under the catalytic action of a metallocene zirconium complex; under the catalytic action of cuprous chloride, reacting with tetraiodo-benzene to generate diiodo-naphthalene; synthesizing a dinaphthalene under the lithiation action of n-butyllithium; and finally synthesizing the dinaphthosilole photoelectric material under the lithiation action of tert-butyllithium. In the synthesis process, the method for preparing the diiodo-naphthalene through coupling reaction of heterocyclopentadiene and polyarylated iodide is simple and high in yield; through the activation action of the n-butyllithium, the dinaphthalene can be synthesized from the bimolecular diiodo-naphthalene; and the metallocene zirconium complex is used as a homogeneous olefin polymerization catalyst, so that the catalytic activity and the olefin polymerization stereoselectivity are high. The synthesized dinaphthosilole is of great use in the fields of conductive high-polymer materials, liquid crystal materials and biological active substances.

Aryne Insertion into I-I σ-Bonds

A new protocol for the efficient synthesis of o-diiodoarenes has been developed. This method allows the synthesis of substituted and polycyclic o-diiodoarenes, which are difficult to obtain by classical methods. This diiodination process involves the formal insertion of arynes into the I-I σ-bond.

Synthesis of capped tetrachelate porphyrins: Towards "insulation" of the chromophore on semiconductor surfaces

A novel "capped" metal-free tetraphenylporphyrin 1, was synthesized and characterized. The cap was designed to "insulate" the chromophoric unit and prevent aggregation as well as undesired contacts on the semiconductor surface. The cap was made of a benze

Tetrakis-azaaromatic quaternary ammonium salts: Novel subtype-selective antagonists at neuronal nicotinic receptors that mediate nicotine-evoked dopamine release

A series of tetrakis-azaaromatic quaternary ammonium salts was synthesized to identify compounds with higher affinity and selectivity as antagonists at neuronal nicotinic receptor subtypes (nAChR) that mediate nicotine-evoked DA release. A high hit rate w

Superactivity and dual reactivity of the system N-iodosuccinimide-H 2SO4 in the iodination of deactivated arenes

Dissolution of N-iodosuccinimide in sulfuric acid gives rise to electrophilic iodine-containing species which are capable of successfully iodinating aromatic compounds with electron-withdrawing substituents in the temperature range from 0 to 20°C. The iodination in sulfuric acid is effected by both protonated N-iodosuccinimide and IOS(O)(OH+)OH intermediate.

1,3-Diiodo-5,5-dimethylhydantoin-An efficient reagent for iodination of aromatic compounds

1,3-Diiodo-5,5-dimethylhydantoin in organic solvents successfully iodinates alkylbenzenes, aromatic amines, and phenyl ethers. The reactivity of electrophilic iodine is controlled by acidity of the medium. Superelectrophilic iodine generated upon dissolution of 1,3-diiodo-5,5-dimethylhydantoin in sulfuric acid readily reacts with electron-deficient arenes at 0 to 20°C with formation of the corresponding iodo derivatives in good yields. The structure of electrophilic iodine species generated from 1,3-diiodo-5,5- dimethylhydantoin in sulfuric acid is discussed.

Oligofunctional amphiphiles featuring geometric core group preorganization: Synthesis and study of Langmuir and Langmuir-Blodgett films

Based on the principle of supramolecular preorganization, a new type of oligofunctional amphiphile, of which compounds 1-4 are representative structures, has been designed and synthesized. The typical feature of their structure is a highly rigid and geometrically well-defined central unit composed of ethynylene substituted aromatic spacers with different numbers of amphiphilic segment groups (also of a rigid geometric design) attached to it. The molecules form well-defined Langmuir films when spread from a solution at the air/water interface or when a 10-4 M aqueous CaCl2 solution was used as the subphase. By analysis of the surface pressure-surface area (π-A) isotherms, information on the packing behavior and orientation of the amphiphilic molecules depending on the molecular structure could be obtained. Morphological characterization of the dynamic process of monolayer compression at the air/water interface was carried out by Brewster angle microscopy, illustrating several phase states visualized as snap shots. Thin monolayer films produced on a 10-4 M aqueous CaCl2 subphase can be transferred to a mica solid support by the Langmuir-Blodgett technique. Tapping mode atomic force microscopy reveals a surface topography of the monofilms composed of 1 and 3 that differ in roughness and also in the properties of elasticity, hardness and adhesive strength. X-Ray crystal structure analysis of three relevant intermediate compounds of the synthesis were successfully determined giving an indication of the potential structural features inherent in the new amphiphiles.
