However, ideal CISS usually requires a relatively ordered and conductive (or insulated but ultrathin) chiral layer, which contradicts the disordered\u2010packing and high\u2010impedance characteristics of chiral molecules, preventing the direct application of most chiral molecules for CISS and increasing the difficulty to prepare chiral spin\u2010selective layers. Here, a general disordered and conductive chiral molecular strategy is proposed to simply construct the small\u2010molecule\u2010based spin polarizer. Directly spin\u2010coating chiral molecules onto the electrode forms the disordered chiral thin film, which exhibits obvious CISS effects demonstrated by an electrochemical oxygen evolution reaction (OER) and a magnetic conductive probe\u2010atomic force microscopy (mcp\u2010AFM). More importantly, by disorderly doping conductive graphite nanoparticles into this film, the high impedance of the chiral molecular layers can be effectively reduced, which results in a higher OER activity with lower H\n 2<\/jats:sub>\n O\n 2<\/jats:sub>\n byproduct and a stronger spin\u2010polarization degree. This can be attributed to a conductivity\u2010enhanced disordered CISS effect, which may lay the foundation for designing universal and high\u2010performance spintronic devices.\n
