Synthesis of conjugated polymers containing biphenyl group and their electro-optical properties

Two types of conjugated polymer, poly(MEHPV-co-BPV)s and poly(MEHPV-alt-BPV), were synthesized by dehydrohalogenation and Honer-Emmons condensation, respectively. Single layer type light-emitting diodes were fabricated utilizing synthesized polymers and t

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.

Dendritic effect on the photoisomerization of 4,4′-distyrylbiphenyl in aqueous solution

Newly synthesized 4,4′-distyrylbiphenyl-cored water-soluble dendrimers underwent trans-to-cis photoisomerization, while the core 4,4′-distyrylbiphenyl underwent cis-to-trans one-way photoisomerization.
