We have introduced self-organizing surface initiated polymerization (SOSIP) as a new versatile route to grow ordered stacks of n-conducting naphtalene diimides (NDI's) with different electronic properties thanks to the different substituents attached to the aromatic core. Thanks to supramolecular interactions such as π-stacking and hydrogen bonding the monomers self-organize and polymerize in covalent NDI stacks growing perpenducularly from the surface from a free thiol initiator. Co-SOSIP of different propagators showed an increase in photocurrent generation activity up to 40 times compared to single color devices. Moreover we were able to control to some extent the self-segregation, thus the activity, of the different NDI's varying the alkyl tail length in their structurizing part. To achieve a better control on the polymerized film, surface templation was explored. Co-SOSIP of two NDI propagators using electrodes with two NDI initiators showed a direct correlation between the initiators molar fraction and the polymerized film composition
