Scientific Research Applications

1. Applications in Organic Photovoltaics

1,8-Diiodooctane (DIO) is primarily used in the field of organic photovoltaics. Its role as a high boiling point solvent additive is crucial in controlling the active layer morphology of bulk-heterojunction organic photovoltaic (OPV) films. OPV devices fabricated using DIO often demonstrate improved efficiency. However, it's important to note that light exposure may cause residual DIO to react with OPV materials, potentially leading to rapid degradation under illumination (Jacobs et al., 2018).

2. Crosslinking in OLEDs and Polymer Solar Cells

DIO has been used to crosslink amino-functionalized polyfluorene, which is significant in the production of organic light-emitting diodes (OLEDs). This crosslinking process renders the polyfluorene film insoluble in non-polar solvents, correlating to the reduction of operational voltage and increase in lifetime of OLEDs (Stolz et al., 2016). Additionally, it is effective in improving the morphology and performance of nonfullerene polymer solar cells (PSCs) by enhancing carrier transport and optimizing morphology (Chen et al., 2019).

3. Impact on Morphology of OPV Devices

The addition of DIO in the preparation of bulk-heterojunction photovoltaic devices has been shown to increase power conversion efficiency through a mechanism of transient plasticization. This process assists in the morphological evolution of the film, promoting molecular mobility and coarsening of phase domains (Zhang et al., 2017).

4. Use in Self-Assembled Monolayers for Biosensors

In the field of biosensor development, DIO has been utilized in the synthesis of amino-terminated semifluorinated long-chain alkanethiols. These compounds form mixed fluorinated self-assembled monolayers (SAMs), providing a new platform system for biosensors (Amato & Calas, 2003).

5. Halogen Bonding in Solid Phase Extraction

DIO is also significant in halogen bonding interactions, especially in the solid phase extraction of perfluorinated iodoalkane. This interaction has been leveraged for the selective extraction of compounds with strong halogen-bonding abilities, showing potential in environmental analysis and pollution monitoring (Yan et al., 2012).
