- Hybrid cyclic dimers of divacant heteropolyanions: Synthesis, mass spectrometry (MALDI-TOF and ESI-MS) and NMR multinuclear characterisation
-
In the field of organic-inorganic hybrid composites, functionalized polyoxometalates constitute a special class of inorganic nanobuilding blocks (NBBs). This study represents a first approach related to the formation of new oligomeric hybrid species based on the reaction of bis(electrophilic) groups with a divacant heteropolyanion as the NBB. Bis(phosphonates) such as para-H2O3PCH2(C6H4) nCH2PO3H2 (n = 1 or 2) have been treated with the divacant heteropolyanion [γ-SiW10O 36]8- to form the hybrid cyclic dimer [H 2((SiW10O36) (O=PCH2(C 6H4)nCH2P=O)]2] 6-. MALDI-TOF and ESI mass spectrometry have been used as essential analytical techniques for the characterization of such composite systems. Wiley-VCH Verlag GmbH & Co.

- Substituent effect on the photochemical and photophysical properties of 4,4′-distyrylbiphenyl derivatives
-
Photochemical properties of 4,4′-distyrylbiphenyl (DSBP) derivatives have been studied. While the introduction of methoxy groups at meta-positions does not influence the photoisomerization of DSBP, the introduction of methyl substituents at the biphenyl moiety (MDSBP) changed the photoisomerization from one-way cis-to-trans photoisomerization for DSBP to cistrans mutual photoisomerization for MDSBP.

- Novel hole transporting materials with a linear π-conjugated structure for highly efficient perovskite solar cells
-
Novel small-molecule hole transporting materials (HTMs) with a linear π-conjugated structure have been synthesized. The perovskite solar cell based on 2TPA-2-DP as the HTM exhibits an encouraging power conversion efficiency of 9.1% under AM 1.5 G (100 mW cm-2) illumination, which is the first demonstration of an effective perovskite solar cell using a linear structured HTM.

- STILBENE DERIVATIVE, METHOD FOR PRODUCING THE SAME, AND ELECTROPHOTOGRAPHIC PHOTORECEPTOR
-
PROBLEM TO BE SOLVED: To provide a stilbene derivative having predetermined substituents in the intramolecular triphenylamine structure, thus improved in compatibility with binder resin and yielding predetermined drum sensitivity properties, to provide a method for producing the stilbene derivative, and to provide an electrophotographic photoreceptor containing the stilbene derivative. SOLUTION: The stilbene derivative is represented by general formula(1) ( wherein, A is a bivalent organic group containing a substituted or nonsubstituted aromatic ring; and R1 to R18 are each H, a substituted or nonsubstituted 1-6C alkyl or the like, wherein at least two of R1 to R18 may be bound to or condensed with each other to form a carbocyclic group or heterocyclic group ). The method for producing the stilbene derivative comprises carrying out a reaction between a specific formylated triphenylamine derivative and a specific diphosphoric ester derivative in the presence of a base. The electrophotographic photoreceptor containing the stilbene derivative is also provided.
