Layer-by-Layer Assembled Films of Perylene Diimide- and Squaraine-Containing MetalâOrganic Framework-like Materials: Solar Energy Capture and Directional Energy Transfer
We
demonstrate that thin films of metalâorganic framework (MOF)-like
materials, containing two perylenediimides (<b>PDICl</b><sub><b>4</b></sub>, <b>PDIOPh</b><sub><b>2</b></sub>) and a squaraine dye (<b>S1</b>), can be fabricated by layer-by-layer
assembly (LbL). Interestingly, these LbL films absorb across the visible
light region (400â750 nm) and facilitate directional energy
transfer. Due to the high spectral overlap and oriented transition
dipole moments of the donor (<b>PDICl</b><sub><b>4</b></sub> and <b>PDIOPh</b><sub><b>2</b></sub>) and acceptor
(<b>S1</b>) components, directional long-range energy transfer
from the bluest to reddest absorber was successfully demonstrated
in the multicomponent MOF-like films. These findings have significant
implications for the development of solar energy conversion devices
based on MOFs
