英文摘要	A novel "Off-On" solid chemosensor based on ordered mesoporous organosilica material was constructed through the co-condensation of rhodamine B organosilanes (RBSi) and tetraethoxysilane (TEOS). The resulting rhodamine B-based hybrid mesoporous organosilicas (RBMSiO2) show good recognition ability for Al3+ on the basis of the "Off-On" mechanism modulated by the Al3+-promoted ring-opening process of the spirolactam structure in the rhodamine B diethylenetriamine (RBD). The photo-stability of RBD could be significantly improved after introducing rhodamine B diethylenetriamine into the framework of RBMSiO2. Upon addition of Al3+, fluorescence emission intensity could increase by 110-fold with the color change from colorless to rose-red, and the detection limit of this hybrid chemosensor towards Al3+ can be as low as 1.3 x 10(-7) M. Accordingly, the RBMSiO2 materials have great potential application in environmental and biological fields for the detection of Al3+.
