4′-bis(2-(4-methoxyphenyl)styryl)-2,2′-bipyridine, (L-OCH3, donor moiety) and substituted polypyridinic ligands with electron acceptor character (NN-A). The NN-A studied ligands were pyrazino[2,3-f][1,10]phenanthroline (ppl), 11-R-dipyrido[2,3-a:2′,3′-c]phenazine (dppz-R; R is H, NO2, or CN) and 10,11-[1,4-naphtalenedione]dipyrido[3,2-a:2′,3′-c]phenazine (Aqphen). The complexes were characterized by IR, NMR, UV–Vis
摘要在这项工作中,我们报告了六种新的钌(II)供体-金属-受体(DMA)型配合物的制备,该配合物具有高吸收性“发色”配体4,4'-bis(2-(4-甲氧基苯基)苯乙烯基)-2,2'-联吡啶(L-OCH3,供体部分)和具有电子受体特征的取代的多吡啶配体(NN-A)。NN-A研究的配体为吡嗪并[2,3-f] [1,10]菲咯啉(ppl),11-R-二吡啶并[2,3-a:2',3'-c]吩嗪(dppz-R ; R为H,NO2或CN)和10,11- [1,4-萘二酮]双吡啶并[3,2-a:2',3'-c]吩嗪(Aqphen)。通过IR,NMR,UV-Vis光谱和循环伏安法对复合物进行表征。通过溶剂变色研究评估了复合物的潜在NLO反应。尽管存在D和A之间的通信,受体部分的变化对配合物性质的影响很小,并且配合物的行为主要由供体配体控制。在可见光区所有配合物所表现出的金属至配体电荷转移带(MLCT)具有
