With the development of the microelectronics technology, personalized intelligent lighting and lighting control systems have been widely utilized in smart buildings to save energy, facilitate people's lives, as well as decorate our community environment. This article presents four bipolar molecules (1-4) with bright color-tunable emission from blue (446 nm) to red (637 nm) light, which were designed and synthesized via constructing a pull-push system. Moreover, these highly thermally stable with tunable fluorescence emission molecules were used as a high-efficient emitter for fabricating stable RGB LED devices with considerable color rendering index (CRI). Furthermore, we designed an electrocircuit system to control the green, red and yellow LED devices using an “ON” and “OFF” switch via voice-activated microelectronics technology. Thus, this study not only provides a molecular strategy to construct tunable-emission materials for multi-color LED device applications, but also offer an efficient example for combining organic synthesis with electronic devices to realize a personalized intelligent lighting and light control system via microelectronics technology.
