Based on the principle of intramolecular charge transfer, naphthimide was selected as the fluorophore and reacted with triphenylamine through a coupling reaction to prepare a naphthalimide derivative organic optical functional small molecule material. The synthesis route is simple and the experimental operating conditions are easy to control, and the yield of target product is very high. Its optical properties were studied. Its optical properties were studied. The optical properties in different solvents mainly showed two strong absorption bands. Its fluorescence emission reached the near infrared region, and exhibited very obvious aggregation-induced emission (AIE) characteristics. The solid showed a strong orange fluorescence phenomenon.
