我们研究了室温下,外加盐反离子在一种阴离子菁J-聚集体中所起的作用。认识到在J-聚集态,反离子按电价关系束缚于染料离子堆叠体邻近。结合人们对聚电解质引起带相反电荷离子菁生成J-聚集体的效应的认识,我们想到:离子菁J-聚集体中,染料离子堆叠体可以起类似于聚电解质的作用,引起带相反电荷的另一离子菁生成J-聚集体。两种J-聚集体以电性相互作用相束缚而形成一种“总体”结构。这样一种“总体”的形成,结合对光谱增感能 We investigated the role played by the addition of salt counterions in an anionic cyanine J-aggregate at room temperature. It is recognized that in the J-aggregation state, the counterion is bound to the dye ion stack in a power-price relationship. In conjunction with our understanding of the effect that polyelectrolytes cause J-aggregates to produce ions with oppositely charged ions, we have come to the conclusion that in ionic cyanine J-aggregates, the dye ion stack can function like a polyelectrolyte to cause oppositely charged Another ionocyanine generates J-aggregates. The two J-aggregates are bound by electrical interactions to form a “total” structure. The formation of such an “overall”, combined with the energy of spectral sensitization
