Photoswitches operating upon ns pulsed laser irradiation
Applied Surface Science, 2005
We present a potential photoswitch, which undergoes reversible mechanical actuation induced exclusively by photons. The photoswitch is a polymer-based film doped with spiropyran photochromic molecules. It undergoes repeatable mechanical cycles controlled by ns laser pulses of specific wavelengths. The polymer matrix is mechanically activated due to particular photoisomerization processes of the incorporated photochromic molecules, resulting in its contraction and lengthening in a highly controllable manner. We present herein the way that the switching time of this novel photoswitch depends on different laser parameters such as the energy and the repetition rate.
Laser control of reactions of photoswitching functional molecules
The Journal of Chemical Physics, 2006
Laser control schemes of reactions of photoswitching functional molecules are proposed based on the quantum mechanical wave-packet dynamics and the design of laser parameters. The appropriately designed quadratically chirped laser pulses can achieve nearly complete transitions of wave packet among electronic states. The laser parameters can be optimized by using the Zhu-Nakamura theory of nonadiabatic transition. This method is effective not only for the initial photoexcitation process but also for the pump and dump scheme in the middle of the overall photoswitching process. The effects of momentum of the wave packet crossing a conical intersection on the branching ratio of products have also been clarified. These control schemes mentioned above are successfully applied to the cyclohexadiene/hexatriene photoisomerization ͑ring-opening͒ process which is the reaction center of practical photoswitching molecules such as diarylethenes. The overall efficiency of the ring opening can be appreciably increased by using the appropriately designed laser pulses compared to that of the natural photoisomerization without any control schemes.
Only one type of lanthanide-doped upconverting nanoparticle (UCNP) is needed to reversibly toggle photoresponsive organic compounds between their two unique optical, electronic, and structural states by modulating merely the intensity of the 980 nm excitation light. This reversible "remote-control" photoswitching employs an excitation wavelength not directly absorbed by the organic chromophores and takes advantage of the fact that designer core-shell-shell NaYF 4 nanoparticles containing Er 3+ /Yb 3+ and Tm 3+ /Yb 3+ ions doped into separate layers change the type of light they emit when the power density of the near-infrared light is increased or decreased. At high power densities, the dominant emissions are ultraviolet and are appropriate to drive the ring-closing, forward reactions of dithienylethene (DTE) photoswitches. The visible light generated from the same core-shell-shell UCNPs at low power densities triggers the reverse, ring-opening reactions and regenerates the original photoisomers. The "remote-control" photoswitching using NIR light is as equally effective as the direct switching with UV and visible light, albeit the reaction rates are slower. This technology offers a highly convenient and versatile method to spatially and temporally regulate photochemical reactions using a single light source and changing either its power or its focal point.
Photochemical characterization of biomimetic molecular switches
Tetrahedron, 2011
The performance of fluorenylideneepyrroline (FPs) and N-alkylated fluorenylideneepyrroline (NAFPs) derivatives for their use as light-driven molecular switches has been studied. Both types of compounds share fast and controllable photoisomerization. Other competitive reaction pathways that could lead to low efficiency have been considered. Only weak fluorescence was measured and high photostability was found when irradiating these compounds for long times, together with high photoisomerization quantum yields. NAFPs are capable of using visible light, which could be useful for practical applications.
A Reversible Photoacid Switched by Different Wavelengths of Light
ChemPhotoChem, 2021
Reversible photoacids have been widely used in different areas for control of proton-driven processes with light. Previously reported reversible photoacids rely on thermal relaxation to return to the low-acidity ground state. Herein we report a photoacid that can be switched between lowacidity and high-acidity states by different wavelengths of light. The photoacid can be converted to a high-acidity metastable state by 470 nm irradiation. The thermal relaxation of the metastable state is very slow and its half-life in DMSO is 55 h. Irradiation with 365 nm light quickly induced the reverse reaction and reached a photostationary state. UV-Vis spectra of the forward and reverse processes induced by 470 nm and 365 nm irradiation respectively have well-matched isosbestic points. No decomposition was observed after the photoacid was switched by the two wavelengths of light for many cycles. Reversible patterning with both writing and erasing steps performed with light was demonstrated using a polymer thin film containing the photoacid and chlorophenol red as the proton acceptor.
