Synthesis and optical characterisation of platinum(II) poly-yne polymers incorporating substituted 1,4-diethynylbenzene derivatives and an investigation of the intermolecular interactions in the diethynylbenzene molecular precursors

Abstract:

A series of 1,4-diethynylbenzene (1) derivatives, H-C≡C-R-C≡C-H with R = C6H3NH2 (2), C6H3F (3), C6H2F2-2,5 (4), C6F4 (5), C6H2(OCH3)2-2,5 (6) and C6H2(OnC8H17) 2-2,5 (7) has been synthesised and their crystal structures determined by single crystal (2-5) or powder (6, 7) X-ray diffraction. The C≡CH⋯πC≡=C hydrogen bonds dominating structure 1 are gradually replaced by C≡C-H⋯F ones with the increase of fluorination (3 → 5), or completely replaced by C≡CH⋯N and NH⋯πC≡C bonds in 2, and C≡CH⋯O in...
