ABSTRACT:
Novel organosilicon compounds having a second order hyperpolarizability coefficient .beta. greater than zero, well suited for use in the field of nonlinear optics, e.g., in telecommunication devices, have the general formula: ##STR1## which n is an integer ranging from 1 to 20; R.sub.1 is an electron donating group; R.sub.2 is an electron accepting group; R.sub.3 is an alkyl radical having from 1 to 8 carbon atoms, a hydrogen atom, an aryl radical, or an R.sub.1 or R.sub.2 radical; and R.sub.4 is an alkyl radical having from 1 to 8 carbon atoms, a hydrogen atom, an aryl radical, or an R.sub.1 radical when R.sub.3 is not an R.sub.2 radical or an R.sub.2 radical when R.sub.3 is not an R.sub.1 radical.
