1D multiblock microstructures for optical waveguides. a Molecule structures of trans-o-BCB and cis-o-BCB. b-c PL peak wavelength change along the three-block heterostructure and the five-block heterostructure; FM images of the three-block and the five-block heterostructures excited at three different positions. d FM images of the microrod with a scale bar of 10 μm. e Energy diagram of the Ir donor and Ru acceptor, ISC: intersystem crossing. ET: energy transfer. f FM images of the microrod at three different positions with a 405 nm laser. The scale bar is 10 μm. g Molecular structure of open-state (L-o) and closed-state (L-c), and bright-field image of open-state and closed-state microrods. The scale bars are 10 μm. h SEM images of open-state and closed-state microrods and bright-field image of open-state and closed-state microrods at different photoradiation time. a-c Reprinted with permission from ref.
