Published in 2021 at "Macromolecules"

DOI: 10.1021/acs.macromol.1c00080

Abstract: Thiazole has been less focused, compared to thiophene, as the building unit for π-conjugated polymers that are used in organic electronic devices despite its electron deficiency and ability to copl... read more here.

Published in 2017 at "CrystEngComm"

DOI: 10.1039/c7ce00956a

Abstract: When Ni(NO3)2·6H2O and N,N′-di(4-pyridyl)-1,4,5,8-naphthalenetetracarboxydiimide (DPNDI) are reacted, a one-dimensional coordination polymer (1) is formed. However, analogous reactions with either terephthalic acid (2) or 2,6-naphthalenedicarboxylic acid (3) and DPNDI affords two-dimensional, pillared metal–organic frameworks. 2 and… read more here.

Published in 2017 at "Dalton transactions"

DOI: 10.1039/c7dt01635b

Abstract: The NiII complex of 5-hydroxy-10,15,20-tris(pentafluorophenyl)-porphyrin was synthesized as the precursor of a negatively charged π-electronic system. Deprotonation, which was examined through UV/vis and 1H NMR spectra, provided an anionic species as the building unit of… read more here.

Published in 2017 at "Chemistry Letters"

DOI: 10.1246/cl.170445

Abstract: Naphthobispyrazine (NPz), a family of naphthalene-based electron-deficient fused heteroaromatic rings, and its derivatives including a polymer are efficiently synthesized via the ring-opening reaction of corresponding naphthobisthiadiazole derivatives. The electrochemical and optical measurements of the NPz-based… read more here.
