[structure: see text] The synthesis, solution redox behavior, EPR, and intramolecularchargetransferproperties of novel donor-acceptor diads of TTF-sigma-A type (TTF = substituted tetrathiafulvalene, sigma = saturated spacer, A = polynitrofluorene acceptor) are reported. The HOMO-LUMO gap for compound 6 is as small as 0.3 eV, and spectroelectrochemical experiments reveal its electrochromic behavior
