Developing new visible light-triggered fluorescent mol. photoswitches is highly desirable for potential application in the fields of photoresponsive optoelectronics and photopharmacol. In this contribution, two novel tetra-/triphenylethene-dithienylethene-BF2bdk triads (TDB1 and TDB2) were designed and prepared by appending tetra-/triphenylethene and BF2bdk moieties at the termini of dithienylethene unit. Before irradiation with blue light at 460-470 nm, they showed an intense emission in solution and in the PMMA film state, suggesting that the AIE effect of tetra-/triphenylethene was inhibited, and functioned only as electron-donating groups. Moreover, upon alternating irradiation with blue/NIR light, TDB1 and TDB2 displayed effective fluorescent switching behaviors and NIR photochromism in toluene and the PMMA film. Therefore, they would be utilized as novel visible light-triggered switches integrated in smart optoelectronic materials. The DFT calculations further validate the differences for their optical properties in the experiments
