Electronic couplings in a 1,3-butadiyne-bridged Zn(II) porphyrin dimer D and trimer T have been probed by measuring their excited-state properties at ensemble and single molecular levels. While single chromophore-like, strongly interacting behaviors are revealed for D, the coupling in T is indicated to be not so strong.
