General Chemical and Physical Properties

The further development of tailor-made surface treatments and pigment preparations will lead to the faster introduction of new applications for inorganic pigments in the future. 

Unsubstituted NDIs are seen as attractive chromophoric units because of their electronic complementarity to ubiquinones and their ease of formation from commercially available starting materials, forming symmetrical and asymmetric analogues relatively efficiently. Simple aromatic diimides undergo single reversible reduction processes either chemically or electrochemically to yield the corresponding radical anion in high yield (E1 = -1.10V vs. Fc/Fc+) (Fc ferrocene) [20a]. 

Reaction conditions (a) acetic acid, amines, 120 °C. (b) alkyl amines, 85 °C. (c) sodium oxides (i.e. NaOMe or NaOEt), rt.

The crystalline mineral silicates have been well characterized and their diversity of stmcture thoroughly presented (2). The stmctures of siHcate glasses and solutions can be investigated through potentiometric and dye adsorption studies, chemical derivatization and gas chromatography, and laser Raman, infrared (ftir), and Si Fourier transform nuclear magnetic resonance ( Si ft-nmr) spectroscopy. References 3—6 contain reviews of the general chemical and physical properties of siHcate materials.
