Multiluminescent nanostructures: The correlation between the
crystallographic structures and the morphologies of a family of
nanostructured lanthanide–phosphono–carboxylates has been investigated.
The luminescence spectra and lifetime distribution of the excited states of
these multiluminescent materials was also studied.

Switchable coloration:
Spirooxazine (SO) and naphthopyran (NP) dyes transform into colored
merocyanine forms under thermal and light stimulation, (see picture
showing a NP dye). They act as effective thermochromic compounds at
high temperature and efficient photochromic compounds at low
temperature.

Supramolecular interaction of a spirooxazine
with amino acids.
Chem. Phys. Lett., 444 (2007) 135-139.
Upon UV irradiation, a spirooxazine converts into a photomerocyanine
which can interact with zwitterionic amino acids. The strength of this
interaction, which is governed by a steric factor, results in a negative
catalysis of the thermal back conversion of the merocyanine to
spirooxazine.

Unexpected chromogenic properties of the 1,3,3trimethylspiro[indoline-2,3’-[3H]naphtho
[2,1-
b][1,4]oxazine] in solid phase: photochromism,
piezochromism and acidichromism
New J. Chem., 28 (2004) 379-386.
The 1,3,3-trimethylspiro(indoline-2,3′)-[3H]naphtho [2,1-b][1,4]oxazine)
in solid phase is sensitive to different external stimulations: it can be
coloured by UV irradiation, increasing pressure and lowering the
environmental pH. Thus it can be defined as a “multi-way” optically
switchable material.
