By self-assembly layer-by-layer technique, ordered multi-layer films being composed of diazonium resin, J-acid, photochromic spiroxazine and poly(sodium-4-styrene)sulfonate (PSS) were alternately fabricated on the glass slide, The fabrication of the multi-layer films was characterized by UV-vis spectroscopy and Atomic Force Microscopy (AFM). During the first bilayer fabrication, azo dye was simultaneously synthesized by diazo coupling reaction between diazonium resin and J-acid coupler. It is displayed from the multi-layer films that spectral chromism effect by spiroxazine moiety was determined. AFM results also show that the multi-dye layer fabrication was successfully obtained by stepwise chemical assembly and that the surface of the multi-layer was relatively uniform.
