AbstractA series of right-hand-side hydroxy functionalized merocyanines containing a powerful cyanodicyanomethylidenedihydrofuran electron acceptor has been designed and synthesized. Using the "build up" approach to synthesis, variations in both the donor moiety and conjugation length of these zwitterionic systems are possible, thereby giving rise to a suite of chromophores. Hyper-Raleigh scattering has confirmed that the highly conjugated chromophores 8c and 10c have large first hyperpolarizabilities (βo) - values that are of a similar magnitude to many of those reported for "bench mark" left-hand-side systems. The hydroxy functionalized chromophores were successfully grafted at various loadings onto a series of recently developed carboxylic acid containing polyetherimides.
