A series of 1,4-diethynylbenzene (1) derivatives, H–CC–R–CC–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 CCH⋯πCC hydrogen bonds dominating structure 1 are gradually replaced by CC–H⋯F ones with the increase of fluorination
一系列1,4-二乙炔基苯(1)衍生物,H–C C–R–C C–H,R = C 6 H 3 NH 2 (2),C 6 H 3 F(3),C 6 H 2 F 2 -2,5(4),C 6 F 4 (5),C 6 H 2(OCH 3)2 -2,5(6)和C 6 H 2(O n C 8 H 17)2 -2,5(7)已被合成,并且其晶体结构确定由单晶(2 - 5)或粉末(6,7)的X射线衍射。与c CH⋯π Ç Ç氢键支配结构1被逐渐被C代替CH⋯˚F那些与氟化的增加(3 → 5),或完全被C代替CH⋯N和NH⋯π Ç Ç键在2和C CH⋯O在6和7中。相关的铂基聚合物,反式-[– Pt(P n Bu 3)2 –C C–R–C C–] n (R =如上,C 6 H 4)已制备并通过光谱法和热重分析表征,表明氨基-和甲氧基衍生物具有最低的热稳定性,而氟化衍生物显示出随着氟化作用的增加而增加的热稳定性。光
