Description
| - 1,2,4,5-Tetrafluorobenzene has been utilized as suitable central acceptor moiety in push-pull chromophores having D-pi-A-pi-D quadrupolar arrangement. Starting from commercially available 1,4-diiodotetrafluorobenzene, nine novel chromophores with systematically extended pi-system were synthesized via cross-coupling reactions. Further electronic tuning has been achieved by variation of the appended donor (N,N-dimethylamino and methoxy groups). Target chromophores were further investigated by X-ray analysis, electrochemical measurements, absorption and emission spectra and theoretical calculations and structure-property relationships were elucidated. Whereas target chromophores showed weak second-order nonlinear responses with beta of 0.18-6.09 x 10(-30) esu, which is primarily given by their centrosymmetric arrangement, third-order polarizabilities gamma of 0.84-22.5 x 10(-27) esu notably exceeded the standard Disperse Red 1 (gamma = 3.47 x 10(-27) esu).
