Osmium-containing conjugated polymer and methods thereof

A main chain comprising an osmapentalyne-containing conjugated polymer, wherein:

• a repeating unit of the osmapentalyne-containing conjugated polymer consists of a first group and a second group,
• the first group consists of a diosmapentalyne compound bridged with a conjugated linking group R1,
• the second group consists of a divinyl group bridged with a conjugated linking group R2,
• a specific structural formula of the repeating unit is as follows:
• a 3rd position and a 3′rd position in the repeating unit are connected by the conjugated linking group R1,
• the divinyl group is connected to a 7th position and a 7′th position of the bis-diosmapentalyne compound;
• the [Os] is OsAL2, wherein A is at least one of —H, halogen, —SCN, or —CN, and L is at least one of a phosphine ligand, a CO ligand, a pyridine ligand, a nitrile ligand, or an isocyanide two-electron ligand,
• the Y is at least one of CH2, O, or C(COO(CH2)kMe)2, and k is an integer between 0 and 18,
• the conjugated linking group R1 is at least one of a first substituted aryl group, a first unsubstituted aryl group, a substituted alkenyl group, an unsubstituted alkenyl group, a substituted alkynyl group, or an unsubstituted alkynyl group, wherein a substituted vinyl group or an unsubstituted vinyl group is a trans vinyl group when the substituted alkenyl group or the unsubstituted alkenyl group is the substituted vinyl group or the unsubstituted vinyl group,
• the conjugated linking group R2 is at least one of the first substituted aryl group, the first unsubstituted aryl group, the substituted alkenyl group, the unsubstituted alkenyl group, the substituted alkynyl group, or the unsubstituted alkynyl group, wherein the substituted vinyl group or the unsubstituted vinyl group is the trans vinyl group when the substituted alkenyl group or the unsubstituted alkenyl group is the substituted vinyl group or the unsubstituted vinyl group,
• the Z− is an anion, and
• the m is an integer between 3 and 300.
