On-off switch of charge-separated states of pyridine-vinylene-linked porphyrin-C60 conjugates detected by EPR.
The design, synthesis, and electronic properties of a new series of D-π-A conjugates consisting of free base (H2P) and zinc porphyrins (ZnP) as electron donors and a fullerene (C60) as electron acceptor, in which the two electroactive entities are covalently linked through pyridine-vinylene spacers of different lengths, are described. Electronic interactions in the ground state were characteriz...

متن کاملSpin dynamics and EPR spectra of charge separated states in photosystem 1 reaction center
A novel strategy is discussed using site-directed spin labeling to study the electron transfer process in photosynthetic reaction centers. An algorithm is presented for numerical simulations of the time-resolved EPR spectra of radical pair states in the presence of an observer spin label. The transient EPR spectra for the radical pair in Photosystem I were simulated for various distances and po...
متن کاملSynthesis of polyvinyl pyridine/C60 conjugates in supercritical carbon dioxide*
In the present investigation efforts have been made to synthesis polyvinyl pyridine (PvPy) /C60 conjugates through 2, 2-azobisisobutyronitrile (AIBN) initiated insitu polymerization of PvPy in scCO2.The process of synthesis was monitored under different reaction conditions ranging 1200-1800psi, 60-90 oC over 6 hours. The progress of polymerization was monitored rheoviscometrically. The concentr...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
