| 1. A conductive ligand for modification of charge transport across a nanostructure-containing matrix, the ligand comprising:
a monomeric body structure comprising a conjugated organic moiety;
a head group coupled to the body structure at a first position on the conjugated organic moiety, wherein the head group comprises
a functionalized head group capable of binding to a nanostructure surface or a head group bound to a nanostructure surface
wherein the nanostructure is a nanocrystal; and
a tail group coupled to the body structure at a second position on the conjugated organic moiety;
wherein the body structure further comprises one or more O-linked or N-linked sidechain coupled to the conjugated organic
moiety, the sidechain comprising a conducting chemical structure, whereby the one or more sidechain extends the conjugation
of the body structure, and
wherein one or more elements of the conductive ligand are capable of removing or adding charges to a nanostructure upon attachment
to a surface of the nanostructure, thereby modifying charge transport across a nanostructure-containing matrix.
