General description

2-Hydroxy-4-(octyloxy)benzophenone (HOBP) is a UV based absorber that has 2-hydroxybenzophenone as a functional group. It can be used to enhance the light fastness of polymers using UV absorbers with sulfur and phosphorus compounds.

Application

HOBPs are UV absorbers for insulating plastics, which can be incorporated with active layers to increase the stabilization of organic solar cells (OSCs). It may be incorporated in parylene C films to enhance the light stability, which can be potentially used as a moisture transfer membrane for electronic boards and photovoltaics.
