The design and synthesis of two semiconducting bis (4-ethynyl-bridging 1, 8-naphthalimide) bolaamphiphiles (BE-NI-COO À and BENI-NH 3 + )t of abricate supramolecular metal-insulator-semiconductor(MIS) nanostructures for biomimetic hydrogen evolution under visible light irradiation is presented. AH 2 evolution rate of ca. 3.12 mmol g À1 •h À1 and an apparent quantum efficiency (AQE) of ca. 1.63 %a t4 00 nm were achieved over the BENI-COO À -NH 3 + -Ni MIS photosystem prepared by electrostatic self-assembly of BENI-COO À with the opposite-charged DuBois-Ni catalysts.T he hot electrons of photoexcited BENI-COO À nanofibers were tunneled to the molecular Ni collectors across asalt bridge and an alkylr egion of 2.2-2.5 nm length at ar ate of 6.10 10 8 s À1 , which is five times larger than the BENI-NH 3 + nanoribbons (1.17 10 8 s À1 ). The electric field benefited significantly the electron tunneling dynamics and compensated the chargeseparated states insufficient in the BENI-COO À nanofibers.

Generally, photocatalytic reaction efficiency decreases quickly with increasing irradiation intensity. Thus, it is a great challenge to achieve a high reaction efficiency under strong irradiation. Volume photocatalysis (VPs) is a new strategy for improving photocatalytic reaction efficiency. Herein, hierarchically porous polymeric carbon nitride (PCN) U‐PCN‐480 as a novel volume photocatalyst is fabricated by a template‐free pyrolysis of needle‐like urea. It is found for the first time that the hierarchical pore structure endows U‐PCN‐480 with the enhanced photoabsorption ability under strong irradiation. Consequently, Pt/U‐PCN‐480 displays excellent VPs activity for hydrogen evolution in the formic acid reaction system. Notably, the activity and apparent quantum efficiency (AQE) are significantly enhanced with increasing irradiation intensity, and the AQE reaches 62.7% and 70.4% at 400 and 380 nm with the irradiation intensity of 30.5 mW cm−2, respectively, the highest values among the reported data for PCN‐based photocatalysts. This effect of enhanced activity and AQE is the result of the synergy between VPs and the enhanced photoabsorption. The findings offer an approach to resolve the difficult problem of low photocatalytic reaction efficiency under strong irradiation and open a way to develop efficient photocatalyst materials and reaction systems.
