Photoactive material having an imide based conjugated backbone

摘要

The invention relates to photoactive material suitable for use as a donor or acceptor in an organic photovoltaic cell, the photoactive material comprising a conjugated backbone comprising at least one chromophore and at least one imide group -OCNR1 CO-, wherein R1 is an organic group forming a conjugated bond with the imide group. This photoactive material can be used in organic solar cells, OLED's and charge transfer material in dye-sensitized solar cells. The invention also relates to a method of preparing this photoactive material, its use and a organic solar cell comprising this photoactive material.
