The Process of Functional Conjugated Organic Polymers Derived from Triple‐Bond Building Blocks

Abstract

Polyacetylenes, poly(p‐phenyleneethynylenes), and polydiacetylenes, as conjugated polymers derived from triple‐bond containing building blocks, attain considerable attention because of their electronic and photoconduction properties. In this review, recent studies on the design and synthesis of conjugated polymers derived from triple‐bond building blocks are summarized with an emphasis on the developments in our group in recent years. Our intense attention is focused on constructing different molecular systems with enhanced light‐harvesting efficiency, and determining the functional properties of conjugated organic polymers. The conjugated organic polymers that appear in this review are useful candidates for various potential applications because of their extraordinary optical and electronic properties. The potential applications of the conjugated polymer‐containing systems are explored.magnified image

Acetylenic Polymers: Syntheses, Structures, and Functions

“…Because a huge volume of work has been done by numerous research groups in the area, it is technically impossible for us to give an exhaustive coverage on the topic. Fortunately, a number of excellent review articles on the specific types of acetylenic polymers such as PAs, PPs, PAEs, and PDAs has already been published, examples of which are given in the reference section, to which interested readers are referred. − Therefore, instead of enumerating every detail with painstaking completeness or comprehensiveness in an encyclopedic fashion, we will use typical examples to tell an integrated story about the synthetic endeavors, structural insights, and function discoveries in the area of acetylenic polymer research, as outlined in Scheme , with an emphasis on the syntheses, structures, and functions that are unique to acetylenic polymers. It should be noted that the term “acetylenic polymers” used here does not refer to “acetylene polymer” or PA only but to all the polymers that are synthesized from acetylenic monomers containing single or multiple carbon−carbon triple bonds.…”

One-pot multicomponent polymerization towards heterocyclic polymers: a mini review

“…are now actively investigating the potential applications and benets of these polymers. [6][7][8][9][10][11] Isocyanides, as a distinctive functional group, exhibit reactivity in tetravalent and divalent carbon forms at extreme resonances. Electrophilic and nucleophilic reactions occur at divalent carbon atoms of isocyanides, leading to their conversion into tetravalent forms through exothermic reactions.…”

New Semiconductors Based on 2,2′-Ethyne-1,2-diylbis[3-(alk-1-yn-1-yl)thiophene] for Organic Opto-Electronics

“…Thus, solution-processed small molecule OPVs with PCEs approaching 7% were reported by Heeger, while rhodanine-based small molecule OPVs have been reported with a PCE of 6.1% . For all these reasons, arylacetylene materials should be considered as attractive OPV donor candidates because their MO energetics can be tuned as broadly as in other families of π-electron materials . Furthermore, stiff triple bonds promote shape consistency within the structure, and rod-like motifs can be varied by modifying the catenation of arylacetylene repeat units .…”
