Incoherent nonlinear photophysical and photochemical processes based on stepwise two-
photon absorption (2PA) processes have been recently used in materials science owing to …

Photoswitchable molecules that undergo nanoscopic changes upon photoisomerisation can
be harnessed to control macroscopic properties such as colour, solubility, shape, and …

This feature article surveys the various ways by which a structurally simple hydrazone can
be used in accessing different functional materials, mainly photo/chemically activated …

The development of fluorescence switchable molecules in several polar and apolar
environments has been required for fluorescence imaging of nanostructures. Photochromic …

We report photochromic donor–acceptor Stenhouse adducts (DASAs) capable of fully
reversible photoisomerization with visible light in organic solvents including chloroform …

Donor–acceptor Stenhouse adducts (DASA) are new-generation photochromic compounds
discovered recently. DASA exist normally in open form (blue/violet) and readily convert to …
