than the reversion to the colorless form. In contrast to, e.g., azobenzenes, the
photoconversion of DTE between its open and closed form is exclusively triggered
by light, making these molecules highly stable towards temperature changes. Also,
when embedded in DMOF-1, DTE exhibits excellent thermal stability, when kept in
the dark for 1 month. To summarize, Benedict and co-workers presented the first
example of an advanced composite with clearly separated absorption bands and a
Fig. 20 (Top) polarized light images of DTE@DMOF-1 single crystals before (a and c) and after
irradiation with UV light (365 nm, b and d). The plane of polarization for a and b ([001]) and c and
d ([100]) is marked with a double arrow; (bottom) polarized absorption spectra of a DTE@DMOF1 crystal after UV light irradiation. Reprinted (adapted) with permission from Ref. [149]. Copyright
