In Situ Raman Monitoring of Silver(I)‐Aided Laser‐Driven Cleavage Reaction of Cyclobutane

Abstract

The cyclobutane cleavage reaction is an important process and has received continuous interest. Herein, we demonstrate the visible laser-driven cleavage reaction of cyclobutane in crystal form by using in situ Raman spectroscopy. Silver(I) coordination-induced strain and thermal effects from the laser irradiation are the two main driving forces for the cleavage of cyclobutane crystals. This work may open up a new avenue for studying cyclobutane cleavage reactions, as compared to the conventional routes using ex situ techniques.

Erasable Photopatterning of Stilbene‐Based Metal‐Organic Framework Films

“…Particularly, MOFs with photoresponsive properties are attracting extensive attention from researchers on various optical applications. To date, the photosensitive MOFs [38] have been realized through a classic [2+2] photocycloaddition [7,[39][40][41][42][43][44][45][46] by building from photoresponsive ligands. [47] So far a series of stilbene-based MOFs have been reported for photoresponsive study due to their unique and effective [2+2] photocycloaddition property, [48][49][50][51] but the fluorescent photoswitch MOFs based on [2+2] photocycloaddition have not been prepared in the form of thin films for erasable photopatterning with various sizes (from ca.…”
