Abstract

Embodiments of linkers for binding semiconductor quantum dots (QDs) to metal oxides are disclosed. The linkers have a general formula F1-A-(F2)_z wherein F1 is —COOH, —COO⁻, —PO₃H₂, —PO₃H⁻, —B(OH)₂, —BO₂H⁻, —SO₃H, —SO₃⁻, —NH₂, —SH, or —S⁻; A is aryl, heteroaryl, aliphatic, or heteroaliphatic; and z≧1 and each F2 independently is —PO₃H₂, —PO₃H⁻, —B(OH)₂, —BO₂H⁻, —SO₃H, —SO₃⁻, or z≧2 and each F2 independently is —COOH, —COO⁻, —PO₃H₂, —PO₃H⁻, —B(OH)₂, —BO₂H⁻, —SO₃H, or —SO₃⁻, or z≧2 and (F2)_z collectively is an oxysilane moiety comprising z lower alkoxy groups bound to silicon. Methods of binding QDs to metal oxides with the disclosed linkers also are disclosed, as well as devices including the QD-functionalized metal oxides.
