Environment-sensitive behavior of fluorescent molecular rotors

Table 1 Overview of the most important groups of molecular rotors with the key spectral properties of one representative example.

Group	Representative example	Peak excitation (approximate)	Peak emission (LE, TICT)	Reference
Benzonitrile-based fluorophores	DMABN	290 nm	342 nm, 460 nm	[6]
Benzylidene malononitriles	DCVJ	489 nm	505 nm¹	[7]
Stilbenes	p-DASPMI	470 nm	560 nm¹	[8]
Arylmethine dyes	Crystal violet	590 nm	630 nm¹	[9]

¹indicates single-band emission from the LE conformation with nonradiative relaxation from the TICT conformation.
