Herein, we submitted to the original synthesis, characterization, energy transfer mechanism of the Bodipy-bearing pillar[5]arene Bodipy and its reactants by employing of infrared, H-1, B-11, C-13, F-19- NMRs, UV-vis, fluorescence spectroscopy, melting point apparatus, CHN elemental analysis and mass spectroscopy. Preliminary UV-vis, fluorescence and excitation measurements were carried out in CH2Cl2 and the results revealed an effective fluorescence resonance energy transfer (FRET) system based on the interaction of pillar[5]arene and Bodipy derivative. epsilon(max) of target molecule reached to a maximum value and it was found as 955 000 M-1 cm(-1). This fluorescent macromolecule worked well for mimicking a light harvesting system with an energy transfer efficiency up to 92%.
