Near-infrared (NIR) reflecting pigments offer the potential to incorporate thermal insulating qualities into paint coatings. Experimental reflectance measurements are presented of a series of perylene based pigments, revealing significant variations in the NIR region as a function of derivatisation and substitution. Theoretical methods are applied to account for the observed trends. Derivatisation...
Arylsilyl substituted pyrene derivatives were synthesized via Suzuki-Miyaura and Hagihara-Sonogashira cross-coupling reactions with boronic acid-terminated and ethynyl-terminated tetraphenylsilane at the 1-, 3-, 6- and 8-positions. The spectroscopic properties of the dyes were investigated in various solvents and in films to assess the suitability of these compounds for optoelectronic applications...
