ABSTRACT:

The charge transfer complexes between phthalocyanine as a donor and benzoquinone derivatives as acceptors vis., 2,3-dichloro-5,6-dicyano-1,4- benzoquinone (DDQ), p-chloranil (CHL) and chloranilic acid (CHLA) were synthesis and investigated by using some modern techniques such as; ICP and Nujol mull technique using spectrophotometer, that after identification and using synthesis and spectral methods, like elemental analysis, IR and ¹H NMR and melting point. Absorption fine structure spectroscopy with the high spatial resolution of X-ray microscopy. Linear Dichroism (LD), the anisotropic absorption of linearly polarised radiation by an oriented molecule, was observed in CT spectra. LD-NEXAFS offers excellent sensitivity to molecular orientation, and can be used to characterise molecular order in materials at high spatial resolution. Also the imaging surface of complexes was confirmed using optical microscope, electron microscope (scanning SEM, transmition TEM). Metal ions under study (Pt, Fe and Hf) wered measured in mille grams per liter . Absorption spectrum was measured using suspension method using paraffin oil to study the electronic transitions for CT complexes. Analyses indicate the particle sizes of CT complex in the rage of 65-85 nm.
