Highly enhanced UV-vis-NIR light harvesting and photoelectric conversion of a pyrene MOF by encapsulation of the D–π–A cyanine dye

Through a facile ion exchange process, cyanine dye can be encapsulated into MOF nanochannels, largely extends the light-harvesting range to visible-light and NIR region, promotes photoelectric conversion performance 15 times higher than that of the pristine MOF.
