An organic-inorganic hybrid material is disclosure. The organic-inorganic hybrid material contains 5&#x2dc;50 wt % of inorganic compounds and has a characteristic peak at 1050&#xb1;50 cmin FTIR spectrum. Furthermore, the invention also provides a fabricating process of the organic-inorganic hybrid material as well as its starting material 'isocyanates'. In particular, the isocyanates are prepared from carbonate containing compounds and amines.

Epoxy/MMT composite material and a crosslinking method for epoxy/MMT composite material with second order nonlinear optical properties are introduced. Chromophore-containing intercalating agents are applied to modify montmorillonites (MMTs) to form organoclays by an ion-exchange process, wherein the chrmophores are neatly packed on exfoliated epoxy/organoclay nanocomposites. As a result, optical nonlinearity, i.e. the Pockels effect is observed for the nanocomposites without resorting to the poling process due to self-assembly process. Furthermore, a series of epoxy/MMT nanocomposites comprising thermally reversible furan-norbornene Diels-Alder adducts are prepared to establish a crosslinking feature. Self-alignment behavior, electro-optical (EO) coefficient and temporal stability of the epoxy/MMT nanocomposites are improved by the Diels-Alders crosslinking.
