| Nonlinear optical (NLO) materials based on organic molecules are believed to be important to the development of optical technologies. Currently, the search for better NLO chromophores is of great interest. One of the major problems facing the field is the efficiency/transparency trade-off: extended pi systems are needed to achieve high polarizabilities and effective second harmonic generation, but increased conjugation often leads to a loss in transparency. We have designed donor/acceptor molecules which rely on the nontraditional conjugation provided by propellane spacers to achieve high-polarizabilty with the required transparency. We will discuss the synthesis of these systems and the effect of different donor and acceptor combinations on the ultraviolet/visible spectra.
