Abstract: Provided herein are photochemical separations. The methods herein can include exposing a first metal complex and a second metal complex to light to facilitate an irreversible chemical reaction to form a modified first metal complex. The modified first metal complex then may be separated from the second metal complex. Compositions also are provided.

Abstract: Forward and back electron transfer at molecule oxide interfaces are pivotal events in dye-sensitized solar cells, dye-sensitized photoelectrosynthesis cells and other applications. Disclosed herein are self-assembled multilayers as a strategy for manipulating electron transfer dynamics at these interfaces. The multilayer films are achieved by stepwise layering of bridging molecules, linking ions, and active molecule on an oxide surface. The formation of the proposed architecture is supported by ATR-IR and UV-Vis spectroscopy. Time-resolved emission and transient absorption establishes that the films exhibit an exponential decrease in electron transfer rate with increasing bridge length. The findings indicate that self-assembled multilayers offer a simple, straight forward and modular method for manipulating electron transfer dynamics at dye-oxide interfaces.

Abstract: Transmission of low energy light is one of the primary loss mechanisms of a single junction solar cell. Molecular photon upconversion via triplet-triplet annihilation (TTA-UC)—combining two or more low energy photons to generate a higher energy excited state—is an intriguing strategy to surpass this limit. The present disclosure is directed to self-assembled multilayers, e.g., bi- or trilayers, on metal oxide surfaces as a strategy to facilitate TTA-UC emission and demonstrate direct charge separation of the upconverted state. A three-fold enhancement in transient photocurrent is achieved at light intensities as low as two equivalent suns. The multilayer structure comprises a substrate comprising a metal oxide surface and a bulk region, and a self-assembled bilayer film, the bilayer film comprising: (a) an acceptor molecule covalently bonded to the metal oxide surface; (b) a linking metal ion bonded to the acceptor molecule; and (c) one or more sensitizer molecule(s) bonded to the linking co-ordinating metal ion.

Abstract: Photopolymers, monomers, compositions including photopolymers and a dopant, and methods, including methods for eliciting a photomechanical response. The dopant may be a triplet sensitizing dopant. The exposing of compositions to the one or more wavelengths of electromagnetic radiation may elicit a photomechanical response via a triplet excited state mechanism.
