introduced into two transmembrane segments that comprise the lateral gate of the bacterial‐membrane‐embedded protein‐conducting pore. Reversible switching of the azobenzene between the trans and cis configurations by irradiation with visible and UV light enforced the opening and closure of the protein‐conducting pore (see scheme).

By introducing a flexible component into a molecular building block, we present an unprecedented alkyl‐decorated flexible crystalline material with a breathing behavior. Its selective adsorption is derived from the breathing effect induced by a guest triggered alkyl transformation. This feature allows the crystal to take up 2.5 mmol g−1 of chloroform with high adsorption selectivity (CHCl3/EA >2000
通过将柔性组分引入分子构件中,我们展示了一种具有呼吸行为的前所未有的烷基修饰的柔性晶体材料。它的选择性吸附源自客体触发的烷基转化所引起的呼吸作用。此功能使晶体能够以高吸附选择性(例如CHCl 3 / EA> 2000)吸收2.5 mmol g -1的氯仿,这意味着在吸附分离和化学传感器中的潜在应用。
acetylcholine receptoragonist iperoxo. We investigated the impact of the substitution pattern on receptor activity and evaluated the different binding modes. Compounds 9b and 15b show excellent photochemical properties and biological activity as fluorination of the azobenzene core alters not only the photochromic behavior but also the pharmacological profile at the muscarinic M1 receptor. These findings
