The use of metal-free diacetylene based polymers to resolve environmental problems is an emerging field of research interest. In this study, two dipeptide functionalized diacetylene based compounds were synthesized. Compound 1 self-assembles to form organogels under certain conditions. Exposure of UV light irradiation on organogel results in the formation of one-dimensional polydiacetylene based conjugated nanoporous covalent organic polymer (PDA-COP 1) nanostructures that demonstrate significant recyclable photocatalytic dye degradation and substantial CO 2 capture ability. Under visible light irradiation, 92% methyl orange degradation is achieved in the presence of PDA-COP 1 after 120 min without the support of any sacrificial reagents or precious metal cocatalysts. Remarkably, surface area is tuned from 0.001 m 2 g −1 (compound 1) to 260.484 m 2 g −1 for the lightinduced developed nanoporous covalent organic polymer (PDA-COP 1). In addition, CO 2 uptake by PDA-COP 1 is increased by 2.45 times more than the CO 2 uptake by the respective monomeric compound 1.

Rational engineering of novel nanohybrid materials for sustainable and efficient energy conversion has gained extensive research interest. Cross-linked nanosheets of organic–inorganic nanohybrids (BSeF/Ni­(OH)2) were fabricated by one-step reductive electrosynthesis and subsequently applied for electrocatalytic water electrolysis. The organic–inorganic nanohybrids consist of benzo­[2,1,3]­selenadiazole-5-carbonyl phenylalanine (BSeF) cross-linked with nickel ions (Ni-BSeF) and nickel hydroxides (Ni­(OH)2), which provide abundant active sites and feasible charge transfer at the electrocatalytic interface. The resulting electrodeposited nanohybrid BSeF/Ni­(OH)2 exhibits bifunctional electrocatalytic performance with 240 and 401 mV of overpotential at +100 and −100 mA cm–2 for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), respectively. The BSeF/Ni­(OH)2 offers a longer electrocatalytic activity of 20 h for OER and HER at applied high current densities of +400 and −200 mA cm–2. Coupled with the high OER and HER activity, the two-electrode-based system of BSeF/Ni­(OH)2 shows a low cell potential of 1.54 V at 10 mA cm–2. The electrocatalytic performance of Ni-BSeF and Ni­(OH)2-based organic–inorganic nanohybrids provides an efficient way to develop a nanohybrid-based catalytic system for energy conversion.
