and highly efficient catalyst for the synthesis of acridinedione derivatives from dimedone, aromatic aldehydes and various amines with great catalytic performance. All the acridinedione compounds were synthesized in DMF in a single process through two successive reactions (aldol condensation and Michael addition) in the presence of highly efficient Pt NPs@GO. The synthesized catalyst was characterized
