International Journal of Photoenergy, Volume 2008, Issue 1, 2008., 2008 This work reports the characterization of composites prepared by the association between zinc phthalocyanine (ZnPc) and titanium dioxide. These composites are better photocatalysts for wastewater decontamination mediated by solar radiation than pure TiO2, performance that remains even when reused.

1-Butyl-2,3,3-trimethylindol-1-ium iodide
IUCrData, 2018 In the title molecular salt, C15H22N+·I−, the fused-ring system is slightly puckered [dihedral angle between the five- and six-membered rings = 3.43 (8)°]. In the crystal, very weak C—H...I interactions link the cations to the anions.
