Abstract
The fluorene derivatives are confirmed as a series of luminescent material with good development prospect and practical value.9,9-dimethyl-9H-fluoren-2-ylboronic acid is the important intermediate for the synthesis of OLED materials.In this thesis,9,9-dimethyl-9H-fluoren-2-ylboronic acid was synthesized by bromination,methylation,Grignard reaction using fluorene as starting material.The conditions which influence the reaction result were investigated and discussed.The process route adopted in the thesis is reasonable with short reaction time and high yield.
