Highly photoluminescent poly(norbornene)s carrying platinum–acetylide complex moieties in their side chains: evaluation of oxygen sensing and TTA–UC

Autor: Fumio Sanda, Hiromitsu Sogawa, Tatsuo Yajima, Toshiko Mizokuro, Taichi Sotani

Publikováno v: Polymer Chemistry. 12:4829-4837

Ring-opening metathesis polymerization (ROMP) of norbornene derivatives is useful for preparing thermally stable and transparent polymeric materials with good moldability. This study deals with the ROMP of the norbornene monomer 1 bearing a platinum(

Triplet-triplet annihilation photon upconversion from diphenylhexatriene and ring-substituted derivatives in solution

Autor: Toshiko Mizokuro, Yoriko Sonoda, Kenji Kamada

Publikováno v: Physical chemistry chemical physics : PCCP. 24(19)

Diphenylhexatriene and its ring-substituted derivatives act as emitters and show blue-green to green upconverted emission under photoexcitation of 640 nm when mixed with a sensitiser molecule (a palladium complex) in solution in a nitrogen atmosphere

Triplet-triplet annihilation upconversion through triplet energy transfer at a nanoporous solid-liquid interface

Autor: Aizitiaili Abulikemu, Yusuke Sakagami, Ritsuki Nishii, Tetsuro Jin, Kengo Suzuki, Kenji Kamada, Toshiko Mizokuro

Publikováno v: Physical chemistry chemical physics : PCCP. 22(32)

We report the triplet–triplet annihilation (TTA) upconversion (UC) through triplet energy transfer (TET) from a sensitiser fixed on a solid surface to free emitters dissolved in solution. A carboxylic-acid derivative of Pt–porphyrin was used as t

Photosynergetic Effects on Triplet–Triplet Annihilation Upconversion Processes in Solid Studied by Theory and Experiments

Autor: Ryuma Sato, Yasuteru Shigeta, Hirotaka Kito-Nishioka, Kenji Kamada, Toshiko Mizokuro

Publikováno v: Photosynergetic Responses in Molecules and Molecular Aggregates ISBN: 9789811554506

Utilization of high density of triplets is important to overcome the dissipation of excitation energy. Triplet–triplet annihilation (TTA) has attracted attention to overcome the conventional limitation for the application of photon upconversion (UC

Organic Photovoltaic Devices Based on Oriented n-Type Molecular Films Deposited on Oriented Polythiophene Films

Autor: Tomoyuki Koganezawa, Toshiko Mizokuro, Tetsuhiko Miyadera, Nobutaka Tanigaki, Yousei Shibata

Publikováno v: Journal of Nanoscience and Nanotechnology. 18:2702-2710

The molecular orientation of π-conjugated molecules has been reported to significantly affect the performance of organic photovoltaic devices (OPVs) based on molecular films. Hence, the control of molecular orientation is a key issue toward the impr

Does Inactive Alkyl Chain Enhance Triplet–Triplet Annihilation of 9,10-Diphenylanthracene Derivatives?

Autor: Kenji Kobayashi, Yasuteru Shigeta, Hirotaka Kitoh-Nishioka, Toshiko Mizokuro, Kenji Kamada, Ryuma Sato

Publikováno v: The Journal of Physical Chemistry C. 122:5334-5340

It has been hypothesized that alkyl chains are inactive for electron transport processes through the chains. However, our theoretical study unveiled that loop-like alkyl chains can accelerate the e...
