Minute amounts of methanol are selectively incorporated within the bulk of α‐glycine crystals, as detected by pyroelectric measurements and impedance spectroscopy. In their Communication (DOI: 10.1002/anie.201800741), E. Meirzadeh, M. Lahav, I. Lubomirsky, and co‐workers show that pronounced differences are observed between the dielectric properties of α‐glycine crystals grown in aqueous solution or alcohol/water mixtures. These differences provide a rational explanation as to why alcohols induce the formation of the metastable β‐polymorph.

通过热释电测量和阻抗谱研究的溶剂诱导的晶体多态性：醇作为α-甘氨酸的特制抑制剂

通过热电测量和阻抗谱检测，少量的甲醇选择性地掺入了大部分α-甘氨酸晶体中。E.Meirzadeh，M.Lahav，I.Lubomirsky及其同事在其交流中（DOI：10.1002 / anie.201800741）发现，在水溶液或酒精中生长的α-甘氨酸晶体的介电​​性质之间存在明显差异/水混合物。这些差异为酒精为什么会诱导亚稳态β-多晶型物的形成提供了合理的解释。
