Photoinduced Reactions of Pyrene with Carbon Tetrachloride on Porous Silica Gel

Abstract: Polyaromatic compounds such as pyrene are adsorbed to the porous silica gel surfaces, and the photoinduced reactions of these species on these surfaces are studied. The pyrene singlet excited state and triplet state are quenched on the surface with coadsorbed carbon tetrachloride (CCl4). Temperature studies with evacuated samples indicate that quenching occurs by CCl4 adsorbed on the surface and not by bombardment from the gas phase. The dynamic quenching rate constant of the pyrene singlet excited state incre… Show more

“…Interaction of CCl 4 with silica has just been reported. 50 These interactions are to be expected because chlorine atoms in organic molecules are known to form weak hydrogen bonds. 51 Styrene, which lacks heteroatoms and is incapable of hydrogen bonding, lacks special attraction to the silica surface and cannot displace CCl 4 from the silica surface.…”
