Exciton dissociation in OSPs can be enhanced by covalently conjugating them with acceptor species displaying higher electron affinity in a double cable polymer (DCP) arrangement, where non\u2010fullerene acceptors (NFAs) are emerging as attractive alternatives. Herein, we report a new all\u2010organic DCP comprising an electron donor polythiophene (PTh) covalently conjugated to an indoloquinoxaline (IQx) NFA (PTh\u2010IQx\u2010DCP). The selection of PTh and IQx as donor\u2013acceptor pair is supported by the experimentally and theoretically determined favorable alignment of their band gaps and energies of HOMOs\/LUMOs. The fluorescence and TRPL profiles reveal enhanced donor\u2010acceptor electronic communication in PTh\u2010IQx\u2010DCP. PTh\u2010IQx\u2010DCP exhibits superior photoelectrochemical characteristics compared to P3HT, IQx, and P3HT+IQx physical hybrid (PH). As photocatalyst, PTh\u2010IQx\u2010DCP produces 906 \u00b1 38 \u00b5M.mg\n                    <jats:sup>\u22121<\/jats:sup>\n                    H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    cumulated over 10 photocatalytic cycles with a 10\u2010cycles apparent average turnover frequency (TOF) of 3.5 h\n                    <jats:sup>\u22121<\/jats:sup>\n                    and an apparent quantum yield (AQY) of 0.8% at 440 nm.
