hexamethine merocyaninyes, the derivatives of fluorene, diphenyl 9H-fluorene-2,7-disulfonate, and bis(2,2,3,3,4,4,5,5-octafluoropentyl) 9H-fluorene-2,7-disulfonate, as well as the derivatives of the heterocycles of moderate (indolylidene and benzotiazolylidene), weak (benzo[c,d]indolylidene and 2,6-diphenylpyrane) and strong (2,6-diphenylpyridine) electron-donor properties were synthesized and their absorption
二,四和六甲亚甲基花青素,芴,二苯基9 H-芴-2,7-二磺酸盐和双(2,2,3,3,4,4,5,5-八氟戊基)9 H的衍生物-芴-2,7-二磺酸盐,以及中度(吲哚基和苯并噻唑基亚烷基),弱度(苯并[ c,d ]吲哚基和2,6-二苯基吡喃)和强度(2,6-二苯基吡啶)杂环的衍生物合成了电子给体性质,研究了它们在不同极性溶剂中的吸收光谱。进行了合成花色素的电子结构的量子化学分析,并以B3LYP / 6-31G(d,p)为基础,通过DFT和TDDFT方法发现了其中的电子跃迁类型。
