Claims

exact text as granted — not AI-modified
1 . A dielectric composition comprising a multi-layered composition, the multi-layered composition comprising periodically alternating layers, the alternating layers comprising (a) one or more layers comprising a silyl or siloxane moiety, (b) one or more layers comprising a π-polarizable moiety, and (c) one or more layers comprising an inorganic moiety comprising one or more main group metals and/or transition metals selected from Zr, Ti, Hf, and Ta. 
   
   
       2 . The dielectric composition of  claim 1 , wherein at least some of the alternating layers are coupled to an adjacent layer by a coupling layer comprising a siloxane matrix. 
   
   
       3 . The dielectric composition of  claim 1 , wherein the silyl moiety has the formula selected from —Si(CH 2 ) n Si—, —Si(CHF) n Si—, and —Si(CF 2 ) n Si—, wherein n is 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10. 
   
   
       4 . The dielectric composition of  claim 1 , wherein the π-polarizable moiety comprises a stilbazolium group. 
   
   
       5 . The dielectric composition of  claim 1  comprising self-assembled monolayers comprising a silyl moiety.

       7 . The dielectric composition of  claim 2 , wherein at least some of the alternating layers are coupled to one another or the siloxane matrix via a condensation reaction. 
   
   
       8 . The dielectric composition of  claim 2 , wherein at least some of the alternating layers are coupled to one another or the siloxane matrix via chemisorption. 
   
   
       9 . A dielectric composition comprising a multi-layered composition, the multi-layered composition comprising one or more layers comprising a silyl or siloxane moiety; one or more layers comprising a π-polarizable moiety; and one or more layers comprising an inorganic moiety comprising one or more main group metals, one or more transition metals and combinations thereof. 
   
   
       10 . The dielectric composition of  claim 9 , wherein at least one of the layers is coupled to an adjacent layer by a coupling layer comprising a siloxane matrix. 
   
   
       11 . The dielectric composition of  claim 9 , wherein the silyl moiety has the formula selected from —Si(CH 2 ) n Si—, —Si(CHF) n Si—, and —Si(CF 2 ) n Si—, wherein n is 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10.

       13 . The dielectric composition of  claim 9  comprising self-assembled monolayers comprising a silyl moiety. 
   
   
       14 . The dielectric composition of  claim 9  comprising self-assembled monolayers comprising a π-polarizable moiety. 
   
   
       15 . The dielectric composition of  claim 9 , wherein the layers are periodically alternating. 
   
   
       16 . The dielectric composition of  claim 9 , wherein a metal is selected from Zr, In, Ga, Ti, Hf and Ta. 
   
   
       17 . A dielectric composition comprising an organic dipolar component comprising a π-polarizable moiety; a siloxane moiety; and a hydrocarbon moiety, each said moiety coupled one to another with silicon-oxygen bonds; and an inorganic component interposed therein, said inorganic component selected from main group metal moieties, transition metal moieties and combinations thereof. 
   
   
       18 . The composition of  claim 17  comprising a hydrocarbon moiety comprising an alkyl group ranging from about C 4  to about C 10 .
