Objectives
Our objective for editing the polyfluorene wiki page is to discuss the class of conjugated polymers with fluorene monomers. These are important materials because of their optical and electronic properties, and are an excellent prototype conjugated polymer with which to discuss relevant property tuning and application. We plan to add an introductory section which describes, in basic terms, what polyfluorene (PF) is. The current page has very little detail about why polyfluorene is important and what it is; our introductory addition will make a brief summary of the page so that anyone can quickly understand the importance of PF and copolymers of it. Next, we plan to add a history section which details the discovery of fluorene and its interesting optical properties which lead to the discovery/synthesis of conjugated PF polymers for their optoelectronic properties. This section will help the reader understand how PF was developed; the current page offers no information about this. Next, we will provide some examples of synthetic routes to obtain PF, relevant in the discussion of this polymer because these routes are part of the property tuning process, and because they face limitations. Next we will discuss (2 sections -PF in industry and adademia…)
Introduction
- What is PF, why is this material interesting, where does it come from and what can be done with it
Discovery of Polyfluorenes and their Interesting Properties
-Discovery of fluorene, its properties and variation of them -Use this moiety in a polymer: polyfluorene copolymers carry the interesting properties of this base monomer. Describe them (PFs and properties) and why people were interested in them -> this motivates the application section later.
Synthesis of polyfluorene and copolymers of fluorene
-Usual conjugated polymer synthetic routes, compared to initial routes -limitations in the synthesis of these materials (reveals limitations to property tuning that is relevant in the applications of this material)
Polyfluorenes as electroactive polymers
- interest in polyfluorene (PF) derivatives has increased because of their high photoluminescence (PL) quantum efficiency, thermal stability, and also their facile color tunability, which can be obtained by introducing low-band-gap co-monomers.
- Previously, researchers have not wanted to work with polyfluorenes because of their poor efficiency
- This has been improved by blending, copolymerization, and end-capping with charge transporting materials to obtain improved charge injection.
- Polyfluorenes are the only class of polymers that emit colors spanning the entire visible range with high efficiency and low operating voltage
Industrial Uses of Polyfluorene
- The use of electroluminescent polymers as the emitting layers in polymer light-emitting diodes (PLEDs) has attracted considerable academic and commercial interest because of the potential of these materials as components in flat-panel displays and lighting applications
- In particular, PF and its derivatives have emerged as suitable PLED materials due to their high photoluminescence (PL) quantum efficiencies, good thermal stabilities, and amenability to functionalization at the 9th-position of fluorene.
