Abstract
AbstractWe have synthesized and characterized putrescine based 2G dendron bearing oligocarboxylic acid as hydrophilic groups (protected as tert‐butyl group) at peripheral positions. The multi‐step synthesis of 2G dendron has been carried out through orthogonal protection‐deprotection strategy. This putrescine based 2G dendron is further utilized for N‐Imide functionalization of perylene dianhydride through imidization reaction to obtained tert‐butyl‐protected PDI 2 followed by acidic deprotection to furnish highly water‐soluble bola‐amphiphile PDI 1. The newly synthesized compounds were characterized by NMR‐spectroscopy, Mass spectrometry, IR as well as by elemental analysis. The PDI 1 showed increased water solubility in acidic and basic mediums.
