Very few monomers have been demonstrated to undergo CTP.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<p>The first reports of CTP came simultaneously from the labs of Yokozawa<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> and McCullough<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> in 2004, with the recognition that <a href="Polythiophene" title="Polythiophene">polythiophene</a> can be synthesized with low dispersity and with control over molecular weight. This recognition sparked interest in polymerization mechanism so that it could be expanded to other monomers. Few polymers can be synthesized via CTP, so most conjugated polymers are synthesized via step-growth using palladium catalyzed <a href="Cross-coupling_reaction" title="Cross-coupling reaction">cross-coupling reactions</a>.

</p>

<div class="mw-heading mw-heading2"><h2 id="Characteristics">Characteristics</h2></div>

<p>CTP is exclusively performed on <a href="Arene" class="mw-redirect" title="Arene">arene</a> monomers to give conjugated polymers. The polymers obtained from CTP are often low dispersity due to its living, chain growth nature. <a href="Mass_spectrometry" title="Mass spectrometry">Mass spectrometry</a> can be used to identify end-groups on the polymer to determine if the polymer was synthesized via chain growth.

</p>

<div class="mw-heading mw-heading2"><h2 id="Types">Types</h2></div>

<p>CTP utilizes cross coupling reactions (see <i>Mechanism</i> below) with monomers containing magnesium-, zinc-, boron-, and tin-based transmetallating groups, giving rise to <a href="Kumada_coupling" title="Kumada coupling">Kumada</a> CTP, <a href="Negishi_coupling" title="Negishi coupling">Negishi</a> CTP, <a href="Suzuki_coupling" class="mw-redirect" title="Suzuki coupling">Suzuki</a> CTP, and <a href="Stille_coupling" class="mw-redirect" title="Stille coupling">Stille</a> CTP reactions.

</p>

<div class="mw-heading mw-heading2"><h2 id="Mechanism">Mechanism</h2></div>

<p>The mechanism of CTP has been debated. The living chain-growth nature of CTP can be explained by the existence of a π-complex (as described in this section) but can also be explained via polymer reactivity.

</p>

<div class="mw-heading mw-heading3"><h3 id="Initiation">Initiation</h3></div>

<p>Initiation from a metal(II) species (either Ni or Pd) involves two monomers transmetalating onto the metal center to form a complex that can undergo reductive elimination. The complex formed after reductive elimination is referred to as a π-complex because the catalyst bound to the π system of the monomer. The catalyst can isomerize to other π-complexes via a process known as "ring-walking" to the π-bond adjacent to a C-X bond at the end of the chain allowing oxidative addition to occur. The product of oxidative addition is an active polymer-metal(II)-halide, and it can react with monomers in the propagation reaction.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading3"><h3 id="Propagation">Propagation</h3></div>

<p>The propagation steps of CTP occurs through a cycle of transmetalation, reductive elimination, ring walking, and oxidative addition. The existence of a π-complex allows for the polymerization to be controlled as it ensures that the catalyst cannot dissociate from the polymer chain (and start new chains). This means that the number of polymer chains at the end of the polymerization should be equal to the number of catalysts in solution, and that the average degree of polymerization of the sample at the end of polymerization should be equal to the ratio of monomers to catalysts in solution.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading3"><h3 id="Termination">Termination</h3></div>

<p>A characteristic of CTP is living chain-growth character, meaning that the catalyst will have a reactive chain end for the entirety of the polymerization. Therefore, to terminate the polymerization, a quenching agent must be added, such as a strong acid to protonate the polymer, or a nucleophile to add an end cap the polymer.

</p><p>If the π-complex is too weakly bound, termination of polymer chains can occur before a quenching agent is added, causing lower molecular weight polymers to form. Current research into CTP focuses on finding catalysts that form strong catalyst-polymer π-complexes such that the polymerization remains living.

</p>

<div class="mw-heading mw-heading2"><h2 id="Analysis">Analysis</h2></div>

<p>Success of CTP is often evaluated using <a href="Gel_permeation_chromatography" title="Gel permeation chromatography">gel permeation chromatography</a>, <a href="Matrix-assisted_laser_desorption/ionization" title="Matrix-assisted laser desorption/ionization">matrix-assisted laser desorption/ionization</a>, <a href="Nuclear_magnetic_resonance_spectroscopy" title="Nuclear magnetic resonance spectroscopy">nuclear magnetic resonance spectroscopy</a>. GPC characterization enables determination of average molecular weight. MALDI and NMR allow for identification of end groups of the polymer chain.

</p>

<div class="mw-heading mw-heading2"><h2 id="Polymer_reactivity_versus_π-complex">Polymer reactivity versus π-complex</h2></div>

<p>The chain growth nature of CTP can also be described without invoking a catalyst-polymer π-complex. If we assume that no π-complex forms and instead every time a monomer was added to a polymer, the polymer becomes more reactive, we would also see chain growth since the largest polymers in the reaction would be the most reactive and would react with monomers preferentially.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> The presence of this mechanism and one mediated by a π-complex can be elucidated by studying the end groups of the polymers using mass spectrometry.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup>
