A variety of fluorescent molecular viscosity probes have been widely used for mapping the
local viscosity in cells and for monitoring the microenvironments in materials. However, their …

The nuclear Overhauser effect (NOE) is a consequence of cross-relaxation between nuclear
spins mediated by dipolar coupling. Its sensitivity to internuclear distances has made it an …

Donor–π–acceptor fluorophores that consist of an electron‐donating amino group and an
electron‐accepting triarylborane moiety generally exhibit substantial solvatochromism in …

Formation of liquid condensates plays a critical role in biology via localization of different
components or via altered hydrodynamic transport, yet the hydrogen-bonding environment …

The viscosity of cell membranes is a crucial parameter that affects the diffusion of small
molecules both across and within the lipid membrane and that is related to several diseases …

The ultimate goal of chemical kinetics is to understand why a given reaction is fast or not. To
this end it is necessary to count on robust and experimentally well tested theories. One of the …

Non-contact localized laser heating-based thermal lensing has emerged as a technique for
probing the heat transport in liquids. A mode-mismatched dual-beam pump–probe …

We report an optical study of quinoxaline-based luminogens derived from 2, 3-bis (aryl)-
quinoxaline-6-carboxylic acid (1a, 1b, and 2) in solution and solid state. These compounds …

A large number of multipolar dyes undergo excited-state symmetry breaking (ESSB) in polar
media. During this process, electronic excitation, initially distributed evenly over the …

The optoelectronic properties of a series of p-phenylene vinylene derivatives are studied
herein to scrutinize their relationship with the molecular flexibility of the peripheral groups …
