a Structures of PPEB-1, PPEB-2, and PPEB-3. b Types of electronic coupling (H- and J-type or the inhibition of coupling) depending on aggregate morphology. c, d Normalized fluorescence spectra (left), normalized time-resolved fluorescence decays (middle), and spectrum full width at half maximum (FWHM) values (right) for single molecules and single aggregates of PPEB-1, PPEB-2, and PPEB-3.
