Abstract
The present invention relates to a facile process for the preparation of non-covalently cross-linked self-assembled perylene bisimide nano structures using hydrogen bonding interactions with poly-4-vinyl pyridine or oligophenylene vinylene (OPV) as structural motif.
Claims11
A facile process for the preparation of self-organized non-covalently cross-linked perylene bisimide nanostructures comprising:
- a) complexing pentadecylphenol perylene bisimide with poly-4-vinyl pyridine or oligophenylene vinylene (OPV) in presence of solvent under stirring for a period ranging between 2 to 24 hrs at a temperature of 30-60° C. to give comb-coil supramolecular complex;
- b) photoinitiated polymerization of comb-coil supramolecular complex as obtained in step (a) in presence of photoinitiator under UV radiation for a period ranging between 5-15 mins at interval ranging between 5-90 seconds using a UV curing spot lamp to obtain said self-organized cross-linked perylene bisimide nanostructures.
