Enhancing light energy harvesting and storage properties of cellulose acetate/azobenzene films through perylene photosensitization

Carbohydrate Polymer Technologies and Applications
This study presents a straightforward approach to enhancing the light energy capture and storage properties of cellulose acetate/azobenzene (CA/Azb) films through photosensitization with a perylene derivative (Py). The films' photoisomerization (trans-to-

Dehydrogenated polycyclic aromatic hydrocarbons and UV bump

, 2008
Recent calculations have shown that the UV bump at about 217.5 nm in the extinction curve can be explained by a complex mixture of PAHs in several charge states.

Re-entrant magnetic field induced charge and spin gaps in the coupled dual-chain quasi-one dimensional organic conductor Perylene$_2$[Pt(mnt)$_2$]

, 2013
An inductive method is used to follow the magnetic field-dependent susceptibility of the coupled charge density wave (CDW) and spin-Peierls (SP) ordered state behavior in the dual chain organic conductor Perylene$_2$[Pt(mnt)$_2$].

Influences of Linker and Nucleoside for the Helical Self-Assembly of Perylene Along DNA Templates

Frontiers in Chemistry, 2019
Six different conjugates of perylene with 2′-deoxyuridine and with 2-amino-2′-deoxyadenosine were synthesized and applied for DNA-templated assembly in aqueous buffer solutions.

Photoinduced Electron Transfer (PET) as Key to Accelerate the Cycloreversion Reaction of Arylquadricyclanes

Chemistry – A European Journal, EarlyView.
It is demonstrated that the photoinduced cycloreversion of a methoxynaphthylquadricyclane in the presence of suitable photocatalysts gives quantitatively the corresponding norbornadiene. As this photochromic norbornadiene‐quadricyclane cycle has favorable properties for light energy conversion, this method provides a useful tool for the targeted ...

Dynamics and Conformational Stability of Chiral Bay‐Phenolate‐Substituted Twisted Octaazaperopyrenedioxides (OAPPDOs)

Chemistry – A European Journal, EarlyView.
Chiral octaazaperopyrenedioxide (OAPPDO) fluorophores were obtained by functionalizing with BINOL and related fragments bridging the bay position. They possess conformational flexibility but remarkable thermal stability with respect to racemization of the central chromophore, which allowed the study of their chiroptical properties, including circular ...
