Principles and Applications of Solvatochromism [PDF]
Applied Spectroscopy, 2001 T he term solvatochromism is used to descr ibe the pronounced change in position and sometimes intensity of a UVvisible absorption band following a change in the polarity of the medium. When absorption spectra are measured in solvents of different polarity it is found that not only the position but also the intensity and shape of the absorption band ...

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection
Advanced Materials, EarlyView.An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

Primer to Voltage Imaging With ANNINE Dyes and Two-Photon Microscopy
Frontiers in Cellular Neuroscience, 2019 ANNINE-6 and ANNINE-6plus are voltage-sensitive dyes that when combined with two-photon microscopy are ideal for recording of neuronal voltages in vivo, in both bulk loaded tissue and the dendrites of single neurons. Here, we describe in detail but for a
