Photophysics and Inverted Solvatochromism of 7,7,8,8-Tetracyanoquinodimethane (TCNQ) [PDF]
, 2019 We report the absorption, fluorescence, and Raman spectroscopy of 7,7,8,8- tetracyanoquinodimethane (TCNQ) in a variety of solvents. The fluorescence quantum yields (QYs) of linear alkane solutions are similar to one another, but QY is shown to acutely ...

Interfacial Force‐Focusing Effect in Mechanophore‐Linked Nanocomposites
Advanced Science, 2020 Enhanced force transmission to mechanophores is demonstrated in polymer nanocomposite materials. Spiropyran (SP) mechanophores that change color and fluorescence under mechanical stimuli are functionalized at the interface between SiO2 nanoparticles and ...

Acidochromic spiropyran–merocyanine stabilisation in the solid state
Acta Crystallographica Section A: Foundations and Advances, 2018 In this work, we present an innovative approach to stabilise the open-ring merocyanine form of a spiropyran compound. In the solid state, the merocyanine form is rarely observed, highlighting the importance of this contribution. Our concept is based on a

Investigating nano-structured domains within ionic liquids: the effect of cation change on thermal equilibrium and relaxation of spiropyran and spirooxazine. [PDF]
, 2009 The established belief that ionic liquids (ILs) behave as homogenous solvents such as that observed in molecular solvents has been challenged.1, 2 Previous use of solvatochromic probe dyes has allowed for the traditional parameter of ‘polarity’ to be ...
