Description
PEG13 is a polymer consisting of ethylene glycol subunits with two terminal hydroxyl groups. The hydroxyl groups can undergo reactions to further derivatize the compound. The hydrophilic properties of the PEG linker increases the water solubility properties of attached compounds in aqueous media.
Uses
Dodecaethylene glycol is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
Application
Dodecaethylene glycol (CAS 6790-09-6, abbreviated as DEG) is a long-chain molecule rich in polar oxygen atoms. It is used to pre-treat the three-layer mesoporous scaffold of printable mesoscopic perovskite solar cells (p-MPSCs) in order to enhance device performance. DEG treatment of the scaffold optimises the wetting sequence between the three layers by improving the wettability of the TiO₂ surface, thereby promoting preferential crystallisation of the perovskite in the bottom TiO₂ layer. Furthermore, the DEG layer effectively buffers residual strain and suppresses harmful defects at the interface. Consequently, the p-MPSC with an optimised interface achieved a power conversion efficiency (PCE) of 20.27% and retained over 92% of its initial PCE after 500 hours of continuous operation under maximum power point tracking conditions [2].
Definition
ChEBI: Dodecaethylene glycol is a poly(ethylene glycol).
