Three types of new polydiacetylenes were synthesized; {poly 6-butanoxy-2, 4-hexadiyne ether (A)}, {poly 1-oxydodecayle – 10, 12-docosadiyane 1, 22-diate (B)}, and {polymer poly 10, 12-docosadiyane 1, 22-4, 4-diamido azo benzene (C)} by using spinning technique thin films were grown on glass substrate. The optical properties were characterized it is found that the measured permeability spectra were high value in the visible and near IR wavelength region. The results showed that the values of optical energy gap for the polymer poly 10, 12-docosadiyane 1, 22-4, 4-diamido azo benzene C is less than the values of A and B. In addition, it is found that the permeability and optical gap decreased with increasing the thickness of thin films.
