Introduction Photochromic compounds undergo a photo-induced reversible isomerization process between two isomers with different absorption spectra upon irradiation with light of appropriate wavelength [1-4].They exhibit different chemical and physical property changes such as their absorption spectra, refractive indices, dielectric constants, oxidation-reduction potentials, and geometrical structures because of their molecular structural changes [5-8].
Although the structure of photochromic compound has been reported, to the best of our knowledge, the properties of the same photochromic compound have not been reported till now.

Furthermore, Kimura and Shirai demonstrated a fibrous network structure of gold nanoparticles constructed by a site-exchange reaction using thiol-terminated gelators [10].
As shown in Fig.1 (a), nanoscaled fibrous structures with length more than one micrometer and mininum width of about 50nm were found and the electronic patterns (ED) of these fibrous structures proved the presence of gold nanoparticles .
The TEM image under dark field shown in Fig. 1 (b) indicated clearly these gold nanoparticles with the size of about 10 nm were contained in the fibrous structures by the oxidized resultants of aniline.
These fibrous structures containing gold nanoparticles will be a novel advanced material valuable for the fabrication of optical and electronic nanodevices.

The influence of AC perturbations on EIS measurement of Copper/LDPE composite with high resistance Yun Wanga, Xiaoxi Hub College of Chemistry & Chemical Engineering, Qinzhou University, Qinzhou, Guangxi, P.
This is possibly because the disturbance to the composite is too large and it makes the internal structure of the composite change.
However, when the perturbation surpasses this scope, it would change the internal structures of materials and cause the result deviating.
The reason is that in the earlier immersion period of 7 days, the increasing perturbation can not change the structure of the composite.
Therefore, the low perturbation would get the good response and change the structure of the composite.
