, (2016/11/17)
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.

7,16-Dihydroheptacenes (1-3) substituted at the 6, 8, 15, and 17 positions are synthesized as blue emitters potentially useful in organic light emitting diodes (OLEDs). The photophysical properties of 1-3 (λmax = 424-428 nm, ΦF = 0.15-0.21, τF = 2.35-2.67 ns in CH2Cl2) are discussed. They are shown to be stable and efficient blue emitters in the solid state (ΦF = 0.37-0.44). The X-ray crystal structure of 1 is reported.
