In this work. a star-shaped planar acceptor named FTr-3PDI was synthesized via ring-fusion between truxene core and three bay-linked perylene diimide (PDI) branches. Compared to the unfused non-planar acceptor Tr-3PDI. FTr-3PDI exhibits better structural rigidity and planarity. https://thegreensjunglebeautyshops.shop/product-category/retinoid-serum/
