The latest results concerning the quantum confinement and other size effects in the nanoferroics are reviewed. The main attention was devoted to the spectral, dielectric and nonlinear optics properties of the nanocomposites based on the single crystals (NH$_2$(C$_2$H$_5)_2)_2$CuCl$_4$ (furthermore DEACC) and (N(C$_2$H$_5)_4)_2$CoCl$_2$Br$_2$ (TEACCB). The peculiarities of the magnetic and dielectric properties were discussed on the example of the low dimensional ferroic (C$_2$H$_5$NH$_3)_2$CuCl$_4$ (EACC). The physical nature of the principally new effects and properties of the nanostructured ferroics is considered. It has been shown that due to the embedding into a polymer matrix in the NC state the ferroic becomes very attractive from the technological point of view. The hygroscopic, brittle and thermally unstable crystals grown from aqueous solution are transformed in such a way that they would be used as principally new nonlinear optics elements, piezotransducers, sensitive materials for sensors, etc.
