We experimentally report a new photoisomerization mechanism of fluorescence resonance energy transfer (FRET) of monomer via photoisomerization. Firstly, a new photoisomerization was firstly report by us, in which trans, trans‐1,4‐Diphenyl‐1,3‐butadiene (tt‐DPB) is photoisomerized to D‐DPB (D stands for rotating double bond) by rotating double bond, evidenced by the three dimensional (3D) and 2D excitation‐emission mappings, and firmly supported by theoretical calculations on potential energy surfaces. Secondly, absorption energy of the photoisomerized D‐DPB is resonated with the fluorescence energy of tt‐DPB. By the electronic state excitation of tt‐DPB, the fluorescence of D‐DPB is observed, which provide evidence of the FRET of DPB via photoisomerization. Our results provide a new mechanism on FRET of monomer via photoisomerization.
