Abstract
A simple and efficient synthetic procedure of 2',7'-dibromo-2,3,6,7-tetraethoxy-9,9'-spirobi [fluoren has been developed. The new monomer of 2',7'-dibromo-2,3,6,7-tetraethoxy-9,9'-spirobi [fluoren has been synthesized in high yields over five steps from readily available starting materials. The new monomer has good solubility in organic solvents such as chloroform, methylene chloride, tetrahydrofuran, ethyl acetate and so on.
