摘要：Special aromatic structure and unique geometric characteristics make subphthalocyanines possess distinctive electronic structures and physicochemical properties. In this paper, tetraarylethylenes with aggregation-induced emission were introduced to subphthalocyanine macrocycles at the axial direction and the periphery to improve the fluorescence emission properties. Results show that the modification at the two different positions of the subphthalocyanines has different effects on regulating the fluorescence performances. The subphthalocyanine modified axially by tetraphenylethylene shows outstanding fluorescence resonance energy transfer (FRET) phenomenon, and the modification on the periphery of subphthalocyanine is conducive to enhance the fluorescence intensity. These distinctive performances have the potential applications in fluorescence sensor and probe. (C) 2021 Elsevier Ltd. All rights reserved.
