In this paper, we have incorporated the aggregation induced emission (AIE) with excited-state intramolecular proton transfer (ESIPT) process into one molecular skeleton for generation of color-tunable emitting materials. As expected, the high air/photo-stability of TPE-based asymmetric Schiff-base chromophores 1–2 displayed clear AIE characteristics and significant advantages in terms of tunable emission containing blue, warm white, as well as orange-red in solution. More importantly, all compounds 1–4 display brilliant colors by adjusting the intensity of blue and red emission in a mixture with a polymer in the solid state. This innovative research would provide a new, efficient channel for the discovery of well-organized full color emitting organic materials.
