Rylene NIR absorption dyes APMI-N (λmax = 796 nm) and (APMI-K, λmax = 787 nm) with compact conjugation, and excellent solubility, were designed and synthesized. Acid/base sensitive dyes 3, 4, 6, and 7 were obtained as well. Their maximum absorption could be adjusted conveniently from 532 nm to 715 nm by adding acid or base in the solvent. Theoretical simulations indicate both protonation of carbonyl
萘嵌苯NIR吸收色素APMI-N(λ最大 = 796纳米)和(APMI-K,λ最大 = 787纳米)与紧凑共轭,并具有优异的溶解性,设计并合成。酸/碱敏感性染料3,4,6,和7以及获得。通过在溶剂中添加酸或碱,可以方便地将其最大吸收值从532 nm调节至715 nm。理论模拟表明的羰基O和电子给予Ø两个质子-在苝酰亚胺起到关键在吸收这些染料的角色转变。
