The invention discloses compounds containing phenyl substituted pyridazine structural unit, and a preparation method and application thereof. The structural general formula of the compounds containing phenyl substituted pyridazine structural unit is disclosed as Formula I. The compounds disclosed as Formula I have proper nuclear magnetic detection; and in order to solve the problems of less research on near-infrared materials and deficiency in high-efficiency high-stability near-infrared luminescent materials at present stage, the invention provides a series of near-infrared luminescent materials containing phenyl substituted pyridazine structure. The compounds have the advantages of accessible raw material, simple preparation process and high overall yield, and have important application value for researching development and application of near-infrared materials.

In this Letter, we demonstrate that linear 2,3-diazanaphthalene (1), 2,3-diazaanthracene (2), and 2,3-diazatetracene (3) can be easily prepared through [4+2] cycloaddition reaction between 3,6-diphenyl-1,2,4,5-tetrazine as the diene and arynes as dienophiles, generated in situ from ortho- aminoarylcarboxylic acids. The physical properties and crystal packing of the prepared compounds 1-3 were fully investigated. In addition, the experimental data (e.g., band gap and band position) are further confirmed by theoretical studies.
NEW SYNTHETIC APPROACH TO BENZO(f)- AND BENZO(g)-PHTHALAZINES
Robev, Stefan K.
, p. 5067 - 5070 (2007/10/02)
Benzo(f)- and benzo(g)-phthalazine derivatives were synthesised from 2-naphthaldazine by means of a Lewis acid mediated cyclization with elimination of naphthalene.
