Synthesis, Structure and Physical properties of 4,4',4'- Triiodine-triphenylamine

摘要

The procedure for the synthesis of 4,4',4"-triiodine-triphenylamine is described. The structure of the compound has been determined by x-ray crystallography. Lattice parameters and space group information are as follows: space group P_(2(1)) a=10.608(2)A, b=11.416(3)A; c=16.088A; α =90°β=107.045(14)°, γ =90°; V=1862.7(7)A~3; Z=4. Diffraction data (Mo K_α radiation 0.71073, 2.06°<θ<26.00°)is collected by P4 diffract meter. The structure was solved and refined by direct method and full-matrix least-squares procedures to R-value of 0.0556. The UV spectrum of this compound is also measured. The photoconducting results show that the compound is good enough to be used as charge transfer material. E_(1/2) of the device based on the compound is 2.5 Lx.s.
