Mechanism of charge accumulation of poly(heptazine imide) gel

Abstract Photo-stimuli response in materials is a fascinating feature with many potential applications. A photoresponsive gel of poly(heptazine imide), PHI, termed PHIG, exhibits photochromism, photoconductivity, and photo-induced charge accumulation, generated using ionic liquids PHI. Although there are several examples liquid gels that exhibit photochromism this the first report an both these properties as well accumulation. We conducted experimental theoretical investigations to understand mechanism photostimulus especially The proposed model explains accumulation dark photocatalysis by PHI provides new concepts field photofunctional materials.
