| Abstract: | Here, we reported a unique twisted rod-like nano-architecture of as-synthesized 4-fluorocinnmaoyl chloride derived polynorbornene (PNORCNF) on the addition of 1-pyrenemethanol (PM) as a sensing probe. A significant change in the PNORCNF/PM microenvironment's polarity was observed with increasing PM concentration keeping the solvent (THF) unaltered. The change in polarity could be well documented with the morphological changes of the PNORCNF/PM system. We proposed π-π interaction between PM and cinnamoyl moiety of PNORCNF for this type of well-controlled hierarchical self-aggregation. |
