英文摘要	A dendron-substituted tetraphenylethene low molecular weight gelator (lmwg)compound, lmwg1, is designed and investigated. gelation induced fluorescence enhancement is observed for the gel based on lmwg1 and its fluorescence can be reversibly tuned by varying the temperature of the ensemble. the photoinduced energy transfer can occur between lmwg1 and pi2 (perylene diimide) in the gel phase, but it cannot occur in the corresponding solution. the emission color of the gel of lmwg1 and pi2 can be tuned from cyan, yellow, to red by varying the concentration of pi2. by taking advantage of the photochromic transformation of spiropyran, the emission color of the organogels based on lmwg1 and sp3 can be switched by alternating uv and visible light irradiations. the emission color can also be tuned by varying the irradiation time. in this way, organogels based on lmwg1 with multiemission color can be achieved in the presence of sp3 after light irradiations.
