Designing non-conjugated donor-acceptor compounds capable of performing energy and charge transfer processes utilized in natural systems for the energy conversation is an important research challenge that received much attention in the last decades.K. R. Justin Thomas...
4) Electron and energy transfer 能量转移与电子传递 5) energy transfer and conversion 能量传递和转换 1. Multiplying the balance equation of a basic extensive quantity by the conjugate basic intensive quantity,a generalized dynamic equation ofenergy transfer and conversionis derived,which indicates the ...
This gives rise to a remarkably stronger contribution of red emission in electroluminescence than in photoluminescence where energy is exchanged exclusively via Förster transfer. The pronounced color change from red to blue with higher degrees of dendronization and larger driving voltages is explained ...
Doping semiconductor nanocrystals with transition metal ions introduces new optical, electronic, and magnetic properties to the host semiconductor nanocrystals. The energy transfer and charge transfer between exciton and dopant ions are the key photophysical processes responsible for the unique properties of ...
the total energy decreases and the luminescence intensity increases.Therefore,we deduce that the energy transfer from guest to host may be derived from the charge transfer.For a given organic electroluminescent device,the maximum value of the conductivity can be observed in a specific dopant ...
Molecular organization of donor–acceptor pairs within a metal–organic framework (MOF) offers a new approach to improving energy and charge transfer at donor–acceptor interfaces. Here, the photo-physical effects of infiltrating MOF-177 (ZnO4(BTB)2; BTB = 1,3,5-benzenetribenzoate) with α,ω...
Femtosecond transient absorption spectroscopy has been used to investigate the excitation wavelength dependence of energy transfer and initial charge separation processes in reaction centers of the purple nonsulfur photosynthetic bacterium Rhodobacter sphaeroides (R-26) at room temperature. The QY transition ...

An energy transfer unit constructed such that a plurality of series-connected circuits which are formed by series-connecting at least windings to and switching means Sa to Sd are provided and that the plurality of series-connected circuits are parallel-connected to a plurality of energy storage mea...
Tuning the role of charge-transfer states in intramolecular singlet exciton fission through side-group engineering The challenge of controlling molecular packing and energy levels in the solid state precludes clear determination of the singlet fission pathway. Here, we circumvent this difficulty by utilizi...
