Windmill-like carbon nanotube structure compound, synthesis method and application

The invention provides a windmill-like carbon nanotube structure compound, a synthesis method and the application. The structural formula is shown in the specification, the structure of the compound is a windmill-like carbon nanotube framework structure, and the compound has good spectroscopic properties. The tested fluorescence emission spectrum shows that the peaks are in a blue light region, and along with the change of the polarity of the solvent, the emission peak position is not changed, and the emission intensity is changed. The emission intensity in the DCM is the maximum, and the emission intensity in the HEX is the minimum.

Gold-catalyzed cyclotrimerization of arynes for the synthesis of triphenylenes

A novel and efficient Au(I)-catalyzed cyclotrimerization of arynes, generated by fluoride-induced elimination of Kobayashi's silylaryl triflates, is described. The reactions led to the formation of triphenylenes in 45-88% yields under mild conditions.

Synthesis of hexabenzotriphenylene and other strained polycyclic aromatic hydrocarbons by palladium-catalyzed cyclotrimerization of arynes

(matrix presented). To evaluate the potential of the recently developed palladium-catalyzed trimerization of arynes for the synthesis of strained polycyclic hydrocarbons, the trimerizations of 1,2-didehydronaphthalene (1) and 9,10-didehydrophenanthrene (2), generated from the corresponding o-trimethylsilylaryl triflates 5 and 11, respectively, were studied. The synthesis of tribenzo[a,g,o]triphenylene (6), tribenzo[a,g,m]triphenylene (7), and hexabenzo[a,c,g,i,m,o]triphenylene (12) is described.

Photochemistry of 1,3,5-Tristyrylbenzene

Depending on the reaction conditions the irradiation of the title compound 1 yields the cyclophane 5, the pyrene derivative 6, or the polycondensed aromatic system 9.An X-ray analysis was performed for 5, representing a new type of cyclophane in which two benzene rings are bridged again by rings.
