The synthesis and photophysical characteristics of a pH responsive near-infrared
fluorescence imaging probe is described. A key feature is the ability to conjugate the probe …

Rotaxane and pseudorotaxane architectures are starting to attract interest as a means of
molecularly encapsulating substrates for potential biological applications.[1–5] Nanovalves …

The chemical and photophysical properties of a fluorescent squaraine dye are greatly
enhanced when it is mechanically encapsulated inside a tetralactam macrocycle. This …

In search for an organic material suitable for the detection of near-infrared electromagnetic
radiation and at the same time capable of air stable operation of related devices, so to …

The interest in squaraine compounds, a relatively old class of cyanine-like dyes, has been
recently renewed due to their potential usefulness in a large number of technologically …

Mechanical encapsulation of fluorescent, deep-red bis (anilino) squaraine dyes inside Leigh-
type tetralactam macrocycles produces interlocked squaraine rotaxanes. The surrounding …

The photophysical properties of two energy‐transfer dyads that are potential candidates for
near‐infrared (NIR) imaging probes are investigated as a function of solvent polarity. The …

Tetrahydroquinoxaline based squaraine dyes synthesized by the condensation reaction
between squaric acid and different tetrahydroquinoxaline derivatives are described. The …

Join or attack: meso‐Cyclam‐substituted heptamethine cyanine dye 1 responds very
differently to the presence of metal ions and protons. Whereas the former are embraced in a …

A series of new squaraine rotaxanes have been synthesised with a tetralactam macrocycle
and stopper groups of varying sizes and functionalities. In chloroform, the relative size of the …
