Molecular photoswitches produce light-controlled changes at the nanometer scale and can therefore be used to alter states behavior of materials in a truly bottom-up fashion. Here we show an escalating photonic complexity material property control with light using recently developed aza-diarylethene combination hemiindigo (HI) photoswitches. First, as photoswitch polystyrene (PS) inscribe relief-type 3D structures reversibly into PS. Second, aza- diarylethene further photoinitiator for light-induced polymerization acrylates, demonstrating first time chemical reactivity its zwitterionic switching state. Third, HIs are implemented polymerized PMA, generating photochromic polymers. At fourth level, binary mixture allows synergize induced photopolymerization localized photochromism simultaneously entrapped functional HI. With such multi-level response, utility this particular applications advanced is demonstrated.
