- The main body of the triphenylamine constructing macrocyclic and a plurality of lateral branch hole transport material, triphenylamine
-
The invention provides a hole-transporting material with main body big ring built by triphenylamine and replaced by a plurality of triphenylamine lateral branches. 2-bromine fluorenone is built to triphenylamine monomer containing functional groups capable of reacting with each other, three molecules of monomers are further cyclized, and at least three triphenylamine lateral branch structures are built at the side of the big ring to form electron-rich hole-transporting material containing a plurality of main body big ring and lateral branches built by triphenylamine through simple chemical reaction. The electron-rich formulae a, b and c big ring type triarylamine compounds have approximate three-dimensional spherical structures. The synthetic electron-rich big ring type triarylamine compounds have high glass transition temperature, can form stable and uniform amorphous form film, do not emit fluorescence with the wavelength of more than 420 nanometers and can be used in a photovoltaic conversion device as the hole-transporting material.
