electronically isolated. The photophysical, electrochemical, and theoretical studies confirm this finding because the properties of nPEC4‐By are comparable to those of the nPEC4‐X oligomers and BODIPY, indicating negligible electron communication between BODIPY and the nPEC4 moieties. Nevertheless, energy transfer (ET) from nPEC4 to BODIPY was rationalized by spectroscopy and theoretical calculations. Its yield
