Abstract: 

The molecules in the graphene confined space show unique nano-confined characteristics, which is used to study the photoelectric properties of the luminescent polymer polyfluorene. The first preparation is reported of the epoxy/carbon nanotube multipleural membrane, with the concentration difference and pressure difference to increase the spontaneous diffusion of the carbon nanotube to the filling efficiency of the carbon nanotube cavity, to avoid the absorption of luminescent material in the outer wall of the carbon nanotube. In this paper, the special luminescence properties of polyfluorene in the carbon nanotube cavity were systematically studied, and it was found that the proposed preparation scheme could not only improve the filling efficiency, but also effectively overcome the defect of poor filling selectivity due to capillary action. After the filling into the carbon nanotube, the spectrum of polyfluorene all showed blue shift, and the degree of blue shift was related to the limited size of the carbon nanotube.
