Claim:
A charge-transport material, comprising: a transition-metal charge-transport material monomer having a structure of Formula I: wherein M is selected from the group consisting of: nickel (II), palladium (II), platinum (II), cobalt (I), iridium (I), rhodium (I), copper (II), copper (III), silver (III), and gold (III); wherein L and L′ are each independently selected from the group consisting of a halogen, NR 3 , PR 3 , NCS, SCN, and CN; wherein R is selected from the group consisting of: a linear or branched, unsubstituted alkyl group with up to 25 carbons; a linear or branched, substituted alkyl group with up to 25 carbons; an unsubstituted aryl group; a substituted aryl group; and when L is PR 3 , R is an alkoxy group (R′O); wherein X and X′ are each independently selected from the group consisting of: S, Se, O, NR′, and a combination thereof; and wherein Z, Z′, Z″ and Z′″ are each independently selected from a polymerizable group, wherein is R′ is selected from a polymerizable group; wherein the polymerizable group is selected from the group consisting of: vinyl; allyl; 4-styryl; acroyl; epoxide; oxetane; cyclic-carbonate; methacroyl; acrylonitrile; isocyanate; isothiocyanate; an epoxide; a strained ring olefin; (—CH 2 ) η SiCl 3 ; (—CH 2 ) η Si(OCH 2 CH 3 ) 3 ; (—CH 2 ) η Si(OCH 3 ) 3 , where η is an integer number from 0 to 25; and a compound having the following structure:
