Disclosed herein are embodiments of complexes exhibiting reversible light-induced magnetization, and/or heat, and/or electrically-induced switching with unprecedented lifetimes. In particular embodiments, the complexes are provided as organic thin films that can exhibit long lifetimes at ambient temperatures. In some representative embodiments, the complex comprises an electronically bistable cobalt complex functionalized with an optically bistable ligand. A photoisomerization-induced spin-charge excited state (PISCES) process can occur, resulting in the direct observation of light-induced spin state switching at room temperature in the solid state.

A series of sterically hindered o-(branched alkoxy)-tert-butoxybenzenes was efficiently prepared in good yields owing to a new practical and simple preparation of o-tert-butoxyphenol starting from catechol and isobutene. Use of DMF di-tert-butyl acetalreagent instead of isobutene/H2SO4 (cat.) for O-tert-butylation was very convenient in case of ortho bulky phenols affording the corresponding tert-butyl
一系列的空间位阻ø - (支链烷氧基) -叔-butoxybenzenes在由于一个新的实用和简单的制备良好的产率被有效地制备ø -叔-butoxyphenol从儿茶酚和异丁烯开始。DMF的使用二-叔丁基缩醛试剂代替异丁烯/ H 2 SO 4(催化量)为ø -叔-butylation是非常方便在的情况下,邻位笨重酚得到相应的叔丁基醚以高收率和纯度。事实证明,这种通用途径是有用的,因为o -di-没有可靠的访问权限t -BuO取代的芳烃。介绍了在拥挤的磷基化合物合成中的应用。
