Bis-PEG4-NHS ester
Based on 1 Customer Validation
Bis-PEG4-NHS ester is a crosslinking reagent and amine-reactive modulator.Bis-PEG4-NHS ester reacts with primary amine groups on liposome surfaces via amide bond formation to covalently attach dibenzylcyclooctyne groups, with a hydrophilic PEG4 spacer reducing steric hindrance for subsequent click chemistry.Bis-PEG4-NHS ester enables site-specific antibody coupling to liposome surfaces via copper-free strain-promoted alkyne-azide cycloaddition click chemistry without disrupting liposome structure in minimal organic solvent volumes.Bis-PEG4-NHS ester undergoes hydrolysis during annealing to form -COOH groups that interact with PbI and FAI to enhance perovskite structural integrity, passivate defects, and modulate nucleation kinetics to regulate crystal growth.Bis-PEG4-NHS ester enhances device efficiency and long-term stability when used as an antisolvent additive for p-i-n perovskite solar cells.

Bis-PEG4-NHS ester can be used for the preparation of highly efficient and stable p-i-n perovskite solar cells, acting as an anti-solvent additive to regulate crystallization kinetics and passivate defects. When Bis-PEG4-NHS ester is added to the anti-solvent as a carboxyl precursor, irreversible hydrolysis occurs during the annealing process of the perovskite film, enabling in-situ conversion of functional groups[2].
