spiropyran–merocyanine system

Extracted Explainers

What the tool is doing

The review identifies spiropyrans as photochromic molecular switches used in drug delivery contexts. They are the core responsive chemical motif underlying the reviewed systems.

Source 1DOI PubMed

Spiropyrans are described as widely used photochromic compounds. The abstract specifically notes gated photochromism achieved by exploiting pKa differences between spiropyran and merocyanine isomers.

Claim 1property statementsupports2021Source 1DOI PubMed

Spiropyran-based drug delivery systems are motivated by spiropyran multi-responsiveness to endogenous and exogenous stimuli and by intrinsic biocompatibility.

Quoted textsource-backed

Due to their multi-responsiveness to endo- and exogenous stimuli, and their intrinsic biocompatibility, they have been utilised in various drug delivery systems (DDSs) to date.
