Abstract
A homochiral microporous hydrogen-bonded
organic framework (HOF-2)
based on a BINOL derivative has been synthesized and structurally
characterized to be a uninodal 6-connected {3<sup>3</sup>5<sup>5</sup>6<sup>6</sup>7} network. This new HOF exhibits not only a permanent
porosity with the BET of 237.6 m<sup>2</sup> g<sup>–1</sup> but also, more importantly, a highly enantioselective separation
of chiral secondary alcohols with ee value up to 92% for 1-phenylethanol
