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 pi-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.
