C 2 -Symmetric 9,9 0 -spirobifluorene-containing polyesters (PEs) were synthesized by polycondensation of 2,2 0 -dihydroxy-9,9 0 -spirobifluorene (1) with bis(acyl chloride)s (2) at 230 C in diphenylether. The molecular weights of PEs 3ae3f were sufficiently high (M w 13,400e41,600). PEs displayed h
