Photorefractive IR-spectrum composites prepared from polyimide and ruthenium(II) tetra-15-crown-5-phthalocyaninate with axially coordinated triethylenediamine molecules

It is established that supramolecular ensembles on the basis of the complex of ruthenium(II) with tetra-15-crown-5-phthalocyanine and axially coordinated triethylenediamine molecules (R₄Pc)Ru(TED)₂, where R₄Pc^2? and TED denote 4,5,4′,5′,4″,5″4?,5?-tetraksis-(1,4,7,10,13-pentaoxatridecamethylene)phthalocyaninate ion and triethylenediamine molecule, respectively) make an aromatic polyamide layer photoelectrically sensitive to 1064-nm Nd:YAG laser radiation, exhibit third-order susceptibility, and, consequently, impart photorefractive properties to the polymer layer at this wavelength.
