Here we propose a universal method to develop neutralized SAM\u2010N molecule through typical acid\u2010base reaction between commonly used SAM molecules and methylamine (MA). In comparison with acid SAM (pH of 3), SAM\u2010N shows neutral nature with pH value of 7, avoiding acid\u2010induced device degradation. Importantly, SAM\u2010N molecules can still assemble on neighboring ITO to regulate the work function and promote holes extraction.
