摘要：

A tetrapodal zwitterionic-type ligand featuring both AIE (aggregation-induced emission) and ILCT (intra-ligand charge transfer) properties, namely 1,1', 1'', 1'''-(4,4', 4'', 4'''-(ethene-1,1,2,2-tetrayl) tetrakis(benzene-4,1-diyl)) tetrakis(methylene) tetrapyridin-4(1H)-one (TPE-4PO) has been designed and applied to the assembly of lanthanide complexes LIFM-21(Ln) (Ln = Sm, Eu, Gd, Tb and Dy). Apart from sensitization of NIR emission of Sm3+ and Dy3+, the resulting ligand and lanthanide complexes show both AIE and ILCT-related photoluminescence behaviors. The photo-response of this system to different aggregation states, solvents' polarity and mechanical grinding was demonstrated by distinguishable emission intensities and colours.
