Spiropyrans have played a pivotal role in the emergence of the field of chromism following
their discovery in the early 20th century, with almost ubiquitous use in materials applications …

Photochromic compounds of the spiropyran family have two main isomers capable of inter-
switching with UV or visible light. In the current review, we discuss recent advances in the …

The development of an easily synthesized, modular, and tunable organic photoswitch that
responds to visible light has been a long-standing pursuit. Herein we provide a detailed …

Self-assembly of a cis-blocked Pd (II) 90° ditopic acceptor [cis-(tmeda) Pd (NO3) 2](M) with a
tetradentate donor L 1 [benzene-1, 4-di (4-terpyridine)] in 2: 1 molar ratio yielded two …

In the past few decades monitoring the concentration of anions has received much interest
due to their role in driving biological processes at low concentrations and toxicity at elevated …

The last few years have seen an explosion of interest in traditional photochromic systems
not only for their applications in variable transmission devices, which continues to attract …

Key approaches to the synthesis of merocyanine dyes are summarised. The dependence of
the dye properties on their chemical structure, the solvent nature and the aggregation type is …

Certain molecular switches respond to input stimulations producing detectable outputs. The
interplay of these signals can be exploited to reproduce basic logic operations at the …

We report on bidirectional photochemical switching of 6, 8-dinitro-1′, 3′, 3′-
trimethylspiro [2 H-1-benzopyran-2, 2′-indoline](6, 8-dinitro-BIPS) between the ring-closed …

Novel photochromic spiropyrans (SPPs) of the indoline series with fluorine substituents and
cationic fragments or formyl groups at positions 6′ and 8′ of the 2 H-chromene moiety …
