Synthesis and Properties of New Glassy Molecular and Oligomer Azocompounds Suitable for Holographic Recordings
Molecular diphenylamine derivative containing two azochromophores has been synthesized. Compound showed formation of stable amorphous glassy phase with good optical quality. Functionalization with bulky trityl- group was carried to further improve physical properties of material. Two types of azochromophore containing polymeric materials, azochromophore in side chain containing aromatic polyether and azochromophores in both, main and side chain, containing polyester were also synthesized. Samples for holographic recording were prepared using spin coating technique from saturated chloroform solution. Holographic recording experiments have been made using 532 and 633 nm lasers. All compounds showed ability of forming laser induced diffraction gratings.
