Bis-PEG4-NHS ester is a crosslinking reagent and amine-reactive modulator[1][2].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[1].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[1].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[2].Bis-PEG4-NHS ester enhances device efficiency and long-term stability when used as an antisolvent additive for p-i-n perovskite solar cells[2].
