The seven kinds of azo-carbazole (ACzE) monolithic dyes were synthesized. The influence of introducing substituents in the para position of the phenyl ring and the distinct strength of the substituents (NO₂, CN, CH₃CO, F, CH₃O, OH and NH₂) on the phenyl ring of the ACzEs was investigated on the basis of spectroscopic and holographic optical aspects. According to the spectroscopic and holographic optical results, we propose here an insight designed to allow updatable full-color holography to the ACzEs, and demonstrated a multi-colour hologram in MACzE/PMMA.
