Thermal fluctuation-induced selective CO₂ uptake of seemingly nonporous N,C-protected dipeptide crystals as elucidated by in situ X-ray crystallographic analysis

Abstract

Described are two experimental findings, i.e., (1) selective CO2 uptake by dipeptide-based molecular crystals of Boc-L-methionyl-L-alanine methyl ester 1 with seemingly nonporous crystal architecture and (2) its CO2 sorption state...
