Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)00:53

Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)

Acyclic diene metathesis polymerization or ADMET polymerization involves cross-metathesis of terminal dienes, such as 1,8-nonadiene, to give linear unsaturated polymer and ethylene. As ADMET is a reversible process, the formed ethylene gas must be removed from the reaction mixture to complete the polymerization process.
Similar to cross-metathesis, ADMET also involves the formation of metallacyclobutane intermediate by [2+2] cycloaddition of one of the double bonds of a terminal diene with...

Olefin Metathesis Polymerization: Overview

Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.
Ruthenium-based Grubbs catalyst is the most commonly used catalyst for olefin metathesis polymerization. Grubbs catalyst consists of a...
[4+2] Cycloaddition of Conjugated Dienes: Diels–Alder Reaction01:16

[4+2] Cycloaddition of Conjugated Dienes: Diels–Alder Reaction

The Diels–Alder reaction is an example of a thermal pericyclic reaction between a conjugated diene and an alkene or alkyne, commonly referred to as a dienophile. The reaction involves a concerted movement of six π electrons, four from the diene and two from the dienophile, forming an unsaturated six-membered ring. As a result, these reactions are classified as [4+2] cycloadditions.
Olefin Metathesis Polymerization: Ring-Opening Metathesis Polymerization (ROMP)01:16

Olefin Metathesis Polymerization: Ring-Opening Metathesis Polymerization (ROMP)

Ring-opening metathesis polymerization or ROMP involves strained cycloalkenes as starting materials. The mechanism of ROMP proceeds by reacting cycloalkene with Grubbs catalyst to give metallacyclobutane intermediate which undergoes a ring-opening reaction to form new carbene. The new carbene reacts with another molecule of cycloalkene. Repetition of these steps leads to the formation of an unsaturated open-chain polymer product. All these steps are reversible, however, relieving the ring...

Area of Science:

  • Materials Science
  • Organic Electronics
  • Photovoltaics

Background:

  • High-performance wide-bandgap polymer (WBG) donors are crucial for advancing nonfullerene organic solar cells (OSCs).

Purpose of the Study:

  • To design and synthesize a novel electron-deficient building block, difuranylphthalimide (DFI), for WBG polymer donors.
  • To investigate the impact of incorporating furan moieties into electron-deficient units for enhanced OSC performance.
  • To develop high-efficiency, sustainable organic photovoltaic materials.

Main Methods:

  • Synthesized a new polymer donor, PDFI, by replacing sulfur with oxygen in dithienophthalimide (DTI) to create the DFI building block.
  • Fabricated binary and ternary organic solar cells using PDFI and state-of-the-art nonfullerene acceptors.
  • Characterized the photophysical properties, blend morphology, and device performance of the fabricated OSCs.

  • The PDFI polymer exhibits a deeper highest occupied molecular orbital (HOMO) energy level, enhanced backbone planarity, crystallinity, and miscibility.
  • Binary OSCs using PDFI achieved a record power conversion efficiency (PCE) of 19.17% for furan-containing donor materials.
  • Ternary OSCs incorporating PDFI demonstrated a PCE exceeding 20%.
