  • The optical properties of three linear conjugated oligomers (F-P, F-P-F, and P-F-P-F-P),where phenothiazine (P) and fluorene (F) groups arrange alternately, are investigated. With the enhancement of the π-conjugated system, their absorption and emission bands both gradually red shift, and their two-photon properties are also improved. Meanwhile, their flu-orescence dynamic traces are analyzed with continuous rate distribution model, exhibiting that their decay rates gradually accelerate and the rate distribution width become narrower. The quantum chemical calculation offers their molecular structures and transition mecha-nism, showing that the enhancement of π-conjugated system should be responsible for the improvement of two-photon properties.

Abstract: The optical properties of three linear conjugated oligomers (F-P, F-P-F, and P-F-P-F-P),where phenothiazine (P) and fluorene (F) groups arrange alternately, are investigated. With the enhancement of the π-conjugated system, their absorption and emission bands both gradually red shift, and their two-photon properties are also improved. Meanwhile, their flu-orescence dynamic traces are analyzed with continuous rate distribution model, exhibiting that their decay rates gradually accelerate and the rate distribution width become narrower. The quantum chemical calculation offers their molecular structures and transition mecha-nism, showing that the enhancement of π-conjugated system should be responsible for the improvement of two-photon properties.
