Abstract: The present application relates to a phthalocyanine, to a method for preparing the phthalocyanine, and to an object coated or impregnated with the phthalocyanine. The present application also relates to a method for providing reactive oxygen species, and to a method for disinfecting materials, including providing reactive oxygen species to the material to disinfect the material by oxidative action.

Abstract: A stretchable structure comprises or is configured to receive a conductive path and an interface region. The interface region comprises a peripheral line comprising at least one inwardly curved portion, such as an “inverted teardrop” or a fjord like recess pointing essentially towards the center area of the interface region. The interface region is arranged to receive said stretchable conductive path via said inwardly curved portion of said peripheral line of said interface region. In this way the interface region minimizes strains or other twisting or stretching forces directed to the conductor entering into the opening of the inwardly curved portion of the interface region.
