Solar-thermochromism of a hybrid film of VO2 nanoparticles and CoII–Br–TMP complexes†
Abstract
A hybrid film consisting of VO2 nanoparticles and CoII–Br–TMP complexes was prepared. The CoII–Br–TMP complexes containing cobalt(II), trimethylolpropane (CH3CH2C(CH2OH)3, TMP) and bromine were selected to be combined with VO2 nanoparticles for the first time. Evident colour-change behaviour in response to temperature change and enhanced optical performance of this composite were reported.
