| 摘 要： | The new chromophore compounds with NLO properties were prepared by Knoevenagel condensation from forrnyl or diformyl calix4/arene and isophorone derivatives in the presence of piperidine and acetic acid, respectively. In these chromophore calix4]arenes, the ring locked trienes were employed as the conjugation bridge and electron acceptor in D-π-A units. The NMR spectra demonstrated that they existed in a cone conformation and consequently non-conjugated D-π-A units could be oriented at nearly the same direction.

| Abstract: | The new chromophore compounds with NLO properties were prepared by Knoevenagel condensation from formyl or diformyl calix4]arene and isophorone derivatives in the presence of piperidine and acetic acid, respectively. In these chromophore calix4]arenes, the ring locked trienes were employed as the conjugation bridge and electron acceptor in D‐π‐A units. The NMR spectra demonstrated that they existed in a cone conformation and consequently non‐conjugated D‐π‐A units could be oriented at nearly the same direction. |
