title: Inhibiting olefin cis, trans-photoisomerization and enhancing electron-accepting ability of a diboryl compound by metal chelation.
abstract: To examine the impact of metal chelation on cis-trans olefin bond isomerization and the photo-stability of N,C-chelate photochromic boron compounds, a new π-conjugated molecule B-BPY that incorporates a 2,2'-bipy unit, two olefin bonds, and two BMes(2)(ppy) chromophores has been synthesized and found to stabilize the molecule toward olefin photoisomerization upon binding with a metal ion.
