This article highlights recent progress in the development of rigid-rod metallopolyyne polymers of late transition metals which can exhibit easily tunable luminescent and electronic properties. Considerable focus is placed on the design strategies towards the tuning capability of phosphorescence emission color and optical bandgap of this class of luminescent metallopolymers, and the evaluation of their suitability as emitters in light-emitting applications, optical power limiters for sensor protection and semiconductors in organometallic photovoltaic cells. An effective approach based on structural modification of the spacer group can be devised to achieve the full-color phosphorescence emission spanning almost the whole visible spectrum and to tune the material properties of these functional organometallic polymers. The major advances, ongoing challenges and future perspectives of this research frontier are also discussed.

“…The ethynyl proton signal is not present but the characteristic nine protons triplet (1.04 ppm) and six proton quartet (0.66 ppm) of the ethyl groups are present. In the 13 For the synthesis of the bis(1 0 -ethynyl-2,5-dimethyloazaferrocenyl) complex of platinum (II) 8, a literature procedure was followed (Scheme 3) [27]. 1 0 -Ethynyl-2,5-dimethylazaferrocene (2) was reacted overnight at room temperature with cis-[Pt(dppe)Cl 2 ] in the presence of a catalytic amount of copper iodide in the solvent mixture diisopropylamine and methylene chloride.…”

“…These onset temperatures also compare well with other related Pt polyynes containing inorganic main group moieties. [12] Decomposition onset was defined by a 5 wt.-% loss. The glass-transition temperatures of P1 and P2 were found to be 152 and 178 8C by DSC analysis, suggesting their amorphous nature.…”

The synthesis, thermal, and photoluminescence properties of novel platinum metallopolyynes of electron‐deficient acridone derivatives with electronically tunable bandgaps and their molecular model complexes are described. Polymer P2 has an optical bandgap (Eg) of 2.10 eV which is much lowered than that of P1 (2.60 eV). The incorporation of electron‐accepting dicyanomethylene units on the acridone ring in the main chain creates a strong π‐conjugated system that features unique donor‐acceptor interactions and intramolecular charge‐transfer states.magnified image
