This study explores the synthesis of two visible light active organic chromophore-based composites using naphthalene monoanhydride (Np) and 1,7-dibromoperylene diester (PMDE). These chromophores feature favorable optical electronic properties polyaromatic skeletons with anhydride functionalities that facilitate π–π interactions between chromophore polymeric carbon nitride (CN) or covalent connections NH2 groups CN. Accordingly, heterogeneous chromophore-CN composite photocatalysts namely, Np/CN(c) PMDE/CN(c) were prepared by adopting in situ calcination (c) Np/CN(a) PMDE/CN(a) ex physical adsorption (a) methods. In exhibited H2 evolution rates (HER) 1069 705 μmol h–1 g–1, respectively, which are significantly higher than HER 465 252 respectively. 10, 7, 4.8, 2.5 times bulk-CN, indicating potential these for efficient photocatalytic evolution. Surface area normalized enhancements 3.8, 5.3, 6.6, 4.2 Np/CN(c), PMDE/CN(c), Np/CN(a), respectively compared to bulk-CN. excellent stabilities under prolonged photoirradiation, consistently increasing exposure time. Additionally, metal-free demonstrated activities towards oxidative amidation aromatic aldehydes, up 80% product yields, establishing prospects combining homogeneous entities a material solar energy harvesting.
