)

)，以及化学计量比（1:1，1:0.99，1:1.01）等反应条件，深入研究了这些因素对聚芴类材料分子量的影响. 研究结果表明，增强有机溶剂与水的混溶性，选用中等强度的无机碱，采用二价钯催化体系，并严格控制反应物的投料比为1:1，有助于合成高分子量的聚芴.

Abstract

Polyfluorene is a typical class of organic conjugated semiconductor materials

which is widely used in the preparation of organic optoelectronic devices

and its molecular weight has a significant effect on the optoelectronic properties. In this study

we focused on the preparation of polyfluorene materials and investigated the effect on the molecular weight of polyfluorene materials by controlling the reaction conditions

such as solvent (tetrahydrofuran/H

toluene/H

-xylene/H

dichloromethane/H

base (K

KHCO

KOH

)

catalyst (Pd(PPh

/P(

) and stoichiometric ratio (1:1

1:0.99

1:1.01). Our results show that the obtained polyfluorene tend to display high molecular weight by increasing the miscibility of organic solvents with water

selecting medium strength inorganic bases

Pd(Ⅱ) catalytic system

and strictly controlling the reaction feed ratio (1:1).
