Absorption/emission and electrochemical properties of four new quadrupolar
push-pull-push molecules with central tetrafluorobenzene acceptor and two
peripheral N,N-dihexylamino and O-hexyloxy donor groups were investigated.
Experimental data were completed with quantum-chemical calculations. The
extent of the intramolecular charge-transfer and nonlinear optical properties were
elucidated in terms of structure-property relationships. The electronic nature of
the appended donor group, length, planarity and composition of the B-linker
(combination of 1,4-phenylene, 2,5-thienylene and acetylenic subunits) are the
most important factors affecting the linear as well as nonlinear optical properties.
